Create a flexible volume that is a clone of a "backing" or "parent" flexible volume. A clone is a volume that is a writable snapshot of another volume. Initially, the clone and its parent share the same storage; more storage space is consumed only as one volume or the other changes. If a specific snapshot name within the parent volume is provided, it is chosen as the parent snapshot. Otherwise, the filer will create a new, distinctively- named snapshot in the parent volume for that purpose. The parent snapshot is locked in the parent volume, preventing its deletion until the clone is either destroyed or split from the parent using the 'volume-clone-split-start' command (see below). This command fails if the chosen parent volume is currently involved in a split operation. This command also fails if the chosen parent volume is a traditional volume. Cloning is a new capability that applies exclusively to flexible volumes.

Input Name	Range	Type	Description
junction-active		boolean optional	This field indicates whether the mounted volume is accessible. The default is true. If the mounted junction path is not accessible, the volume does not appear in the owning virtual server's namespace. This field applies only to Cluster-Mode volumes.
junction-path		string optional	The Junction Path at which this volume is to be mounted. The fully-qualified pathname in the owning vserver's namespace at which a volume is mounted. Note that this pathname may itself contain junctions, one for each volume (other than the namespace root volume) that provides storage along the pathname's length. As with all fully-qualified pathnames , this string must begin with '/'. In addition, it must not end with '/'. An example of a valid junction path is: '/user/my_volume'. Only one volume can be mounted at any given junction path. If an incorrect junction path is specified, EINVALIDINPUTERROR is returned. If another volume is mounted at the specified junction path, EVOLALREADYMOUNTED is returned.
parent-snapshot		string optional	Name of the snapshot within 'parent-volume' that is to serve as the parent snapshot for the clone. If not provided, the filer will create a new snapshot named 'clone_parent_' (using a freshy-generated UUID) in 'parent-volume' for this purpose.
parent-volume		string	Name of the parent flexible volume for the clone.
space-reserve		string optional	Specifies the type of volume guarantee for the clone. Possible values: none, file, volume. If this argument is not provided, then guarantee type is inherited from parent volume.

Begin the process by which the given clone is split off from its underlying parent volume and snapshot. New storage is allocated for the clone that is distinct from its parent. This process may take some time and proceeds in the background. Use the 'volume-clone-split-status' command to view the operation's progress. Both clone and parent volumes remain available during the process of splitting them apart. Upon completion, the snapshot on which the clone was based will be unlocked in the parent volume. Any snapshots in the clone are removed at the end of processing. Use the 'volume-clone-split-stop' command to stop this process. This command fails if applied to a traditional volume. Cloning is a new capability that applies exclusively to flexible volumes. In Data ONTAP Cluster-Mode, a job is created to perform the split operation.

Create a volume. The maximum number of volumes (traditional or flexible in any combination) on a filer is determined by the amount of main memory. All filers with less than 8GB of memory can support a maximum of 200 volumes, and all others can support a maximum of 500 volumes. The detailed behavior of this API depends on where it is received: 1. In Data ONTAP Cluster-Mode, create a new flexible volume. 2. In Data ONTAP 7-Mode, create a new flexible, traditional, or sparse volume with the given name and characteristics. Freshly-created traditional volumes may not be operational immediately after the API returns. Use 'volume-list-info' to obtain information about volumes, including the status of the newly-created traditional volume in order to determine when it is fully operational.

Input Name	Range	Type	Description
antivirus-on-access-policy		string optional	The name of the Anti-Virus On-Access policy. The default policy name is 'default'. If not specified when creating a volume, the Anti-Virus On-Access Policy is inherited from the owning vserver. Currently, this policy can only be managed using the 'antivirus' command line interfaces.
containing-aggr-name		string optional	Flexible volumes only. The name of the aggregate in which to create the new flexible volume. If provided, this argument must be accompanied by the "size" parameter described below. This input is required for creating a Cluster-Mode volume.
export-policy		string optional	The name of the Export Policy to be used by NFS/CIFS protocols. The default policy name is 'default'.
flexcache-cache-policy		string optional	The name of the FlexCache cache policy. The default policy name is 'default'. This policy applies only to FlexCache volumes and can be created using the 'flexcache-cache-policy-create' API.
flexcache-fill-policy		string optional	The name of the FlexCache prefill policy. The default policy name is 'default'. This policy applies only to FlexCache volumes and can be created using the 'flexcache-fill-policy-create' API.
flexcache-origin-volume-name		string optional	The name of the origin volume that contains the authoritative data. This field is valid only for a FlexCache volume. The origin volume must belong to the same vserver that owns this volume.
group-id	[0..2^32-1]	integer optional	The UNIX group ID for the volume. The default value is 0 ('root').
index-dir-enabled		boolean optional	If true, index directory format is enabled. Default: false.
is-junction-active		boolean optional	This field indicates whether the mounted volume is accessible. The default is true. If the mounted junction path is not accessible, the volume does not appear in the owning virtual server's namespace. This field applies only to Cluster-Mode volumes.
is-nvfail-enabled		string optional	If true, the controller performs additional work at boot and takeover times if it finds that there has been any potential data loss in this volume due to an NVRAM failure. For 7-Mode volumes, it causes the invalidation of all NFS file handles on all volumes affected by the problem so that client-side users are forced to remount the affected file system (and thus not continue to use potentially incorrect data). It is also possible to specify a set of files per volume that are to be renamed out of the way in these cases. The controller sends error messages to the console whenever such problems are found. For Cluster-Mode volumes, the volume would be put in a special state called 'in-nvfailed-state' such that protocol access is blocked. This will cause the client applications to crash and thus prevent access to stale data on the volume. To get out of this situation, the admin needs to manually clear the 'in-nvfailed-state' on the volume. By default, this value is false.
is-vserver-root		boolean optional	If true, this volume is the namespace root volume of the vserver which owns this volume. The default value is false. When creating a volume, if this field is set to true, the new volume is to become the new namespace root volume of the vserver. This field can be used in a recovery scenario in which the namespace root volume of the vserver becomes unrecoverable.
junction-path		string optional	The Junction Path at which this volume is to be mounted. The fully-qualified pathname in the owning vserver's namespace at which a volume is mounted. The pathname is case insensitive and must be unique within a Vserver's namespace. Note that this pathname may itself contain junctions, one for each volume (other than the namespace root volume) that provides storage along the pathname's length. As with all fully-qualified pathnames , this string must begin with '/'. In addition, it must not end with '/'. An example of a valid junction path is: '/user/my_volume'. Only one volume can be mounted at any given junction path. If an incorrect junction path is specified, EINVALIDINPUTERROR is returned. If another volume is mounted at the specified junction path, EVOLALREADYMOUNTED is returned.
max-dir-size	[0..2^63-1]	integer optional	The maximum size (in bytes) to which any directory in this volume can grow. For 7-Mode volumes, the default setting of 10240 limits directory size to 10 MBytes and allows it to hold up to approximately 300,000 files. For Cluster-Mode volumes, the default setting is 100 MBytes and it allows the directory to hold up to approximately 3,000,000 files. The number of files that the directory actually can hold varies depending on such things as the length of the names and whether it needs to use double-byte UNICODE characters. Most users should not need to change this field's default setting. It is useful for environments where system users may grow a directory to a size that starts impacting system performance. When a user tries to create a file in a directory that is at the limit, the system returns a ENOSPC error and fails the create.
max-write-alloc-blocks	[0..2048]	integer optional	The maximum number of blocks used for write allocation. This feature is deprecated.
size		string optional	Flexible volumes only. The initial size of the new flexible volume. The format to use is: < number > k|m|g|t where "k" means kilobytes, "m" means megabytes, "g" means gigabytes, and "t" means terabytes. If provided, this argument must be accompanied by the "containing-aggr-name" parameter described above.
snapshot-policy		string optional	The name of the snapshot policy. The default policy name is 'default'. This policy can be created using the 'snapshot-policy-create' API. It can be managed using the 'snapshot-policy-*' APIs.
space-reserve		string optional	Specifies the type of volume guarantee the new volume will use. Possible values: none, file, volume. If this argument is not provided, the default volume guarantee type is volume.
unix-permissions		string optional	Unix permission bits in octal string format. It's similar to Unix style permission bits: In Data ONTAP 7-mode, the default setting of '0755' gives read/write/execute permissions to owner and read/execute to group and other users. In Data ONTAP Cluster-Mode, for security style "mixed" or "unix", the default setting of '0700' gives read/write/execute permissions to owner and no permissions to group and other users. For security style "ntfs", the default setting of '0000' gives no permissions to owner, group and other users. It consists of 4 octal digits derived by adding up bits 4, 2 and 1. Omitted digits are assumed to be zeros. First digit selects the set user ID(4), set group ID (2) and sticky (1) attributes. The second digit selects permission for the owner of the file: read (4), write (2) and execute (1); the third selects permissions for other users in the same group; the fourth for other users not in the group.
user-id	[0..2^32-1]	integer optional	The UNIX user ID for the volume. The default value is 0 ('root').
volume		string	Name of the volume to create. The volume name can contain letters, numbers, and the underscore character (_), but the first character must be a letter or an underscore. In Data ONTAP Cluster-Mode, the volume names must be unique within a Vserver. In Data ONTAP 7-mode, the volume names must be unique on a controller.
volume-comment		string optional	A description for the volume being created.
volume-security-style		string optional	The security style associated with this volume. Possible values: 'mixed' ... Mixed-style security, 'ntfs' ... NTFS/Windows-style security, 'unix' ... Unix-style security (default setting) Security styles don't apply to GX-striped data volumes.
volume-state		string optional	Desired state of the volume after it is created. Possible values: 'online', 'restricted', 'offline'
volume-type		string optional	The type of the volume to be created. Possible values: "rw" - read-write volume (default setting), "ls" - load-sharing volume, "dp" - data-protection volume, "dc" - data-cache volume (FlexCache)

Take the specified volume or plex offline, making it unavailable for both user-level data access and RAID-level access (unless it's a flexible volume, at which time its containing aggregate is not affected in any way, and will remain fully online). The operation takes effect before the API returns except in maintenance mode, when the current root volume may not be taken offline. A volume marked to become the root cannot be taken offline. Taking a flexible volume offline does not affect its containing aggregate in any way. A number of operations being performed on the given volume (or its containing aggregate) can prevent this operation from succeeding, either at all or for various lengths of time. If such operations are found, the system waits up to one second for them to finish. If they don't, the command is aborted. A check is also made for files on the volume opened by internal ONTAP processes. The command is aborted if any are found. Plexes are not supported for Cluster-Mode volumes.

Input Name	Range	Type	Description
name		string	Name of an existing volume or plex. If a volume contains CIFS shares, users should be warned before taking the volume offline. Use "cifs-delay" to specify number of seconds to wait. If a plex is specified, the plex must be part of a mirrored volume, and both plexes must be online. Prior to offlining a plex, the system will flush all internally-buffered data associated with the plex and create a snapshot that is written out to both plexes. The snapshot allows for efficient resynchronization when the plex is subsequently brought back online.

Bring the specified volume or the plex online. This command takes effect immediately. If there are CIFS shares associated with the volume, they are enabled. Plexes are not supported for Cluster-Mode volumes.

Input Name	Range	Type	Description
name		string	Name of an existing volume or plex. If a volume is specified, it must be currently offline, restricted, or foreign. If the volume is foreign, it will be made native before being brought online. A ``foreign'' volume is a traditional volume that consists of disks moved from another filer and that has never been brought online on the current filer. Traditional volumes that are not foreign are considered ``native.'' If the volume is inconsistent, but has not lost data, it is advisable to run WAFL_check or wafliron (or do a 'snapmirror initialize' in case of a replica volume) prior to bringing an inconsistent volume online. Bringing an inconsistent volume online increases the risk of further file system corruption. If the volume is inconsistent and has experienced possible loss of data, it cannot be brought online unless WAFL_check or wafliron (or 'snapmirror initialize') has been run on the volume. If a plex is specified, the plex must be part of an online mirrored traditional volume or aggregate. The system will initiate resynchronization of the plex as part of online processing.

Set the option named 'option-name' to the value specified by 'option-value' in the specified volume. The change remains effective even after the filer is rebooted. Some options have values that are numbers or strings, and others have values that are 'on' (also expressible as 'yes', 'true', or '1' ) or "off" (also expressible as 'no', 'false', or '0'). A mixture of uppercase and lowercase characters may be used for an option's value. Note that the 'root' option is special in that it does not have an associated value. Also, note that some of these options can NOT be set for a flexible volume, as they relate only to aggregates (either free-standing ones or those embedded in traditional volumes). Other options may only apply for flexible volumes.

Input Name	Range	Type	Description
option-name		string	Name of the option to be set. Possible values: "convert_ucode" (value: "on" | "off") Setting this option to "on" forces conversion of all directories to UNICODE format when accessed from both NFS and CIFS. By default, it is set to "off", in which case access from CIFS causes conversion of pre-4.0 and 4.0- format directories. Access from NFS causes conversion of 4.0 format directories. This option cannot be set on a Cluster-Mode volume unless it was transitioned from 7-Mode. "snapshot_clone_dependency" (value: "on" | "off") Setting this option "on" will unlock all initial and intermediate backing snapshots for all inactive LUN clones. For active LUN clones, only the backing snapshot will be locked. If the option is "off" the backing snapshot will remain locked until all intermediate backing snapshots are deleted. This option is not valid for a Cluster-Mode volume. "create_reserved" This option is no longer supported. "create_ucode" (value: "on" | "off") Setting this option to "on" forces UNICODE format directories to be created by default, both from NFS and CIFS. The default value is "off", in which case all directories are created in pre-4.0 format and only converted to UNICODE format upon the first CIFS access. This option cannot be set on a Cluster-Mode volume. "extent" (value: "on" | "space_optimized" | "off") Setting this option to "on" enables extents in the volume. This causes application writes to be written in the volume as a write of a larger group of related data blocks called an extent. Using extents may help workloads that perform many small random writes followed by large sequential reads. However, using extents may increase the amount of disk operations performed on the filer, so this option should only be used where applicable. The default value is "off", in which case extents are not used. The value "space_optimized" indicates extent updates will not duplicate snapshot blocks into the active file system, thereby using space conservatively. The "space_optimized" value may result in degraded snapshot read performance; and may only be used for flexible volumes. "fractional_reserve" (value: < number >) This option decreases the amount of space reserved for overwrites of reserved objects (LUNs, files) in a volume. The option is set to 100 by default and indicates that 100% of the required reserved space will actually be reserved so the objects are fully protected for overwrites. The value can vary from 0 to 100. Using a value of less than 100 indicates what percentage of the required reserved space should actually be reserved. This returns the extra space to the available space for the volume, decreasing the total amount of space used. However, this does leave the protected objects in the volume vulnerable to out of space errors since less than 100% of the required reserved space is actually reserved. If reserved space becomes exhausted this will cause disruptions on the hosts using the objects. If the percentage is decreased below 100%, it is highly recommended that the administrator actively monitor the space usage on the volume and take corrective action if the reserved space nears exhaustion. "fs_size_fixed" (value: "on" | "off") Setting this option to "on" causes the file system to remain the same size (and not grow) when a SnapMirror relationship is broken, or when a "vol/aggr add" is performed on it. This option is automatically set to be "on" when a volume becomes a SnapMirrored. It remains "on" after the "snapmirror break" command is issued for the volume. This option allows a volume to be SnapMirrored back to the source without needing grow the source volume. If the volume size is larger than the file system size, turning off this option forces the file system to grow to the size of the volume. "guarantee" (value: "none" | "file" | "volume") Flexible volumes only. Setting this option controls the type of space reservation for the named flexible volume. There are three possible settings. The first, "none", provides no guarantee that there will be enough blocks in the containing aggregate to meet the flexible volume's needs. The second, "file", guarantees there will be enough blocks in the containing aggregate to meet the needs of the specified files in the flexible volume. The third, "volume", is the default setting and guarantees there will be enough blocks available in the containing aggregate to meet the entire flexible volume's needs. An error will be returned if an attempt is made to set this option on a traditional volume. "ignore_inconsistent" (value: "on" | "off") This option can only be set in maintenance mode. If set to "on", then the root volume may be brought online when booting even if it is marked as inconsistent. The user is cautioned that bringing it online prior to running WAFL_check or wafliron may result in further file system inconsistency. "maxdirsize" (value: < number >) Set the maximum size (in KBytes) to which any directory can grow. The default setting of 10240 limits directory size to 10 MBytes and allows it to hold up to approximately 300,000 files. The number of files that the directory actually can hold varies depending on such things as the length of the names and whether it needs to use double-byte UNICODE characters. Most users should not need to change this option's setting. This option is useful for environments where system users may grow a directory to a size that starts impacting system performance. When a user tries to create a file in a directory that is at the limit, the system returns a ENOSPC error and fails the create. "max_write_alloc_blocks" (value: < number >) Set the maximum number of blocks used for write allocation. The default setting, 0, uses the system-wide default number of blocks, which should be optimal for most users. Some sequential read workloads may benefit from increasing this value. On rare occasions, some multi-stream sequential write workloads may benefit from decreasing this value. Range: [0..2048]. "minra" (value: "on" | "off") Setting this option to "on" causes the filer to perform minimal read-ahead on this volume. By default, this option is "off", causing the filer to perform very aggressive read-ahead on the volume. "no_atime_update" (value: "on" | "off") Setting this option to "on" prevents the update of inode access times when a file is read. This option is useful for volumes with extremely high read traffic, since it prevents writes to the inode file for the volume from contending with reads from other files. It should be used carefully. That is, use this option when you know in advance that the correct access time for inodes will not be needed for files on that volume. "no_i2p" (value: "on" | "off") Setting this option to "on" disables inode to parent pathname translations on the volume. The default setting is off. "nosnap" (value: "on" | "off") Setting this option to "on" disables automatic snapshots on the volume. This option is not supported for Cluster-Mode volumes. "nosnapdir" (value: "on" | "off") Setting this option to "on" disables the visible .snapshot directory that is normally present at system internal mount points. It also turns off access to all other .snapshot directories in the volume. "nvfail" (value : "on" | "off") If this option is on, the filer performs additional work at boot time if it finds that there has been any potential data loss due to an NVRAM failure. In such situations, it causes the invalidation of all NFS file handles on all volumes affected by the problem so that client-side users are forced to remount the affected file system (and thus not continue to use potentially incorrect data). It is also possible to specify a set of files per volume that are to be renamed out of the way in these cases. The filer sends error messages to the console whenever such problems are found. "raid_cv" (value: "on" | "off") Traditional volumes only. Setting the option to "off" disables block checksum protection on the volume. The default is "on". The user is cautioned that turning off the option exposes the filesystem to inconsistency that could be caused by a misbehaving hardware component in the system. "raid_zoned" (value: "on" | "off") Traditional volumes only. Setting the option to "off" disables zoned checksum protection on the volume. The default is "on". The user is cautioned that turning off the option exposes the filesystem to inconsistency that could be caused by a misbehaving hardware component in the system. "raidsize" (value: < number >) Traditional volumes only. The maximum size of a RAID group within the traditional volume. Changing this option doesn't cause existing RAID groups to grow or shrink. Rather, it only affects whether more disks will be added to the last existing RAID group in the future, and how large new RAID groups will be. "raidtype" (value: "raid4" | "raid_dp") Traditional volumes only. The type of RAID group used for this traditional volume. The "raid4" setting provides one parity disk per RAID group, while "raid_dp" provides two. Changing this option immediately changes the RAID group type for all RAID groups in the traditional volume. When upgrading RAID groups from "raid4" to "raid_dp", each RAID group begins reconstruction onto a spare disk allocated for the second "dparity" parity disk. "read_realloc" (value: "on" | "space_optimized" | "off") Setting this option to "on" enables read-reallocation in the volume. This causes application reads to optimize the layout of parts of a file or LUN after the data has been read from disk and is in the appliance memory. The default value is "off", in which case read-reallocate is not used. The value "space_optimized" indicates read-reallocate updates will not duplicate blocks into the active file system, thereby using space conservatively. The "space_optimized" value may result in degraded snapshot read performance; and may only be used for flexible volumes. "resyncsnaptime" (value: < number >) Traditional volumes only. Sets the RAID mirror resynchronization snapshot frequency to be the given number of minutes. The default value is '60' (minutes). "root" (value: < none >) The specified volume is to become the root volume for the filer on the next reboot. This option can be used on only one volume at any given time. The existing root volume will become a non-root volume after the reboot. Until the system is rebooted, the current root volume will continue to show 'root' as one of its options, and the new root volume will show 'diskroot' as an option. In general, the volume that has the 'diskroot' option value is the one that becomes the root volume following the next reboot. The only way to remove the root status of a volume is to set it on another one. "schedsnapname" (value: "create_time" | "ordinal") Setting the option to "ordinal" causes scheduled snapshots to be named in the hourly.n name format. Setting the value to "create_time" causes snapshots to use a hourly.yyyy-mm-dd_hhmm name format instead. The default is "ordinal". "snapmirrored" (value : "off") If SnapMirror is enabled, the filer automatically sets this option to "on". Set this option to "off" if SnapMirror should no longer be used to update the mirror. After setting this option to "off", the mirror becomes a regular writable volume. This option can only be set to "off" with this interface. Only the filer can change this option's value from "off" to "on". This option is not settable in Data ONTAP Cluster-Mode. Use "snapmirror-break" API instead. "try_first" (value : "volume_grow" | "snap_delete") If the flexible volume is configured to automatically reclaim space if the volume is running out of space, then setting this option to "volume_grow" will cause the volume to increase in size before deleting snapshots. If the option was set to "snap_delete", snapshots will be deleted before the volume size is increased. "svo_enable" (value: "on" | "off") Setting this option to "on" enables SnapValidator functionality on this volume. This option only applies to non-root volumes. This option is unsupported in Data ONTAP Cluster-Mode. "svo_allow_rman" (value: "on" | "off") Setting this option to "on" enables SnapValidator functionality on this volume to allow this volume to contain Oracle RMAN backup data. This option only applies to non-root volumes. This option is unsupported in Data ONTAP Cluster-Mode. "svo_checksum" (value: "on" | "off") Setting this option to "on" enables SnapValidator checksumming of all writes to this volume. This option only applies to non-root volumes. This option is unsupported in Data ONTAP Cluster-Mode. "svo_reject_errors" (value: "on" | "off") Setting this option to "on" enables SnapValidator functionality to reject any write to the volume which fails the SnapValidator checks. This option only applies to non-root volumes. This option is unsupported in Data ONTAP Cluster-Mode. "thorough_scrub" (value: "on" | "off") Traditional volumes only. Setting the option to "on" enables thorough scrub on a block checksum volume. That means that a scrub will initialize any zeroed checksum entries that it finds. If there are any checksum entries to be initialized, scrub will run slower than normal. "snaplock_autocommit_period" (value: "none" | h|d|m|y) SnapLock volumes only. This option defines the criteria for committing files to WORM on a SnapLock volume by the autocommit scanner. h, d, m, y denote hours, days, months and years respectively. The default value of this option is "none" that corresponds to autocommit being disabled in the SnapLock volume. The minimum autocommit period on a SnapLock volume is 2h. Any valid value other than "none", specified in hours (h), days (d), months (m) or years (y) would trigger the autocommit scanner on the Snaplock volume. "snaplock_default_period" (value : min | max | infinite | s|h|d|m|y) This option can be set only for SnapLock volumes and specifies the default retention period that will be applied to files committed to WORM state without an associated retention period. If this option value is min then snaplock_minimum_period is used as the default retention period. If this option value is max then snaplock_maximum_period is used as the default retention period. If this option value is infinite then infinite retention period will be used as the default retention period. WORM files with infinite retention period are retained forever. The retention period can also be explicitly specified as a number followed by a suffix. The valid suffixes are s for seconds, h for hours, d for days, m for months and y for years. For example, a value of 6m represents a retention period of 6 months. The maximum valid retention period is 70 years. This option is not applicable while extending retention period of an already committed WORM file "snaplock_maximum_period" (value: infinite | s|h|d|m|y) This option can be set only for SnapLock volumes and specifies the maximum allowed retention period for files committed to WORM state on the volume. Any file committed with a retention period longer than snaplock_maximum_period will be assigned a retention period equal to snaplock_maximum_period. If this option value is infinite then files can be committed for infinite retention period in the volume. WORM files with infinite retention period are retained forever. The retention period can also be explicitly specified as a number followed by a suffix. The valid suffixes are s for seconds, h for hours, d for days, m for months and y for years. For example, a value of 6m represents a retention period of 6 months. The maximum valid retention period is 70 years. This option is not applicable while extending retention period of an already committed WORM file "snaplock_minimum_period" (value: infinite | s|h|d|m|y) This option can only be set for SnapLock volumes and specifies the minimum allowed retention period for files committed to WORM state on the volume. Any file committed with a retention period shorter than snaplock_minimum_period will be assigned a retention period equal to snaplock_minimum_period. If this option value is infinite then every file committed to the volume will have a infinite retention period. WORM files with infinite retention period are retained forever. The retention period can also be explicitly specified as a number followed by a suffix. The valid suffixes are s for seconds, h for hours, d for days, m for months and y for years. For example, a value of 6m represents a retention period of 6 months. The maximum valid retention period is 70 years. This option is not applicable while extending retention period of an already committed WORM file

Given the name of a flexible volume, either return its current size or set the volume's size to the stated amount.

Input Name	Range	Type	Description
new-size		string optional	Specify the flexible volume's new size using the following format: [+|-]< number > k|m|g|t] If a leading '+' or '-' appears, it indicates that the given flexible volume's size is to be increased or decreased (respectively) by the indicated amount, else the amount is the absolute size to set. The optional trailing 'k', 'm', 'g', and 't' indicates the desired units, namely 'kilobytes', 'megabytes', 'gigabytes', and 'terabytes' (respectively). If the trailing unit character doesn't appear, then < number > is interpreted as the number of kilobytes desired. The file system size of a readonly replica flexible volume, such as a snapmirror destination, is determined from the replica source. In such cases, the value set using "volume-size" is interpreted as an upper limit on the size. A flexible volume that's not a readonly replica which has the "fs_size_fixed" option set may have its size displayed, but not changed. Attempting to set the volume size in this case will result in failure and a EINTERNALERROR error code. Users must be able to adjust readonly replica flexible volume size in order to maintain enough capacity to accommodate transfers from the replica source. Attempting to set a readonly replica destination size to be less than that of its source will result in a failure indicated by the EONTAPI_ENOSPC error code.

Compatible target aggregate information When returned as part of the output, all elements of this typedef are reported, unless limited by a set of desired attributes specified by the caller. When used as input to specify desired attributes to return, omitting a given element indicates that it shall not be returned in the output. In contrast, by providing an element (even with no value) the caller ensures that a value for that element will be returned, given that the value can be retrieved. When used as input to specify queries, any element can be omitted in which case the resulting set of objects is not constrained by any specific value of that attribute.

fsid		string optional	The File System Identifier (FSID) value that serves as one of this volume's internal indicies. This value serves as an internal index for a volume. All volumes on a given controller must have unique FSIDs, except for the two special values described below: A value of 0 indicates that this volume does not currently have a legal FSID for some unexpected reason. Such volumes are forcibly kept offline until this attribute is assigned a legal value. A value of 1 indicates that this volume has recently appeared on its current controller due to having its aggregate be copied from a different controller. All volumes in this newly-created aggregate must be assigned legal, controller-unique IDs when they are onlined. That will be handled automatically by WAFL upon mount. If modifiable, this field may be set only when the volume is restricted. It may be set to any value that is not currently being used by any other volume on the same controller. If a request to set this value to '0' is received, the system will select a new value that is currently unused. Note that setting a volume's FSID sometimes has external effects. In particular, a 7-Mode volume's FSID is part of the NFS file handles constructed for its files. Attributes: non-creatable, non-modifiable
instance-uuid		uuid optional	Universal unique identifier (UUID) for the volume that remains unchanged when the volume is moved to a new location. This differs from the volume's regular UUID which changes after a move. The instance UUID can be used to identify a volume even after it is moved. This field is valid for flexible volumes only. UUIDs are formatted as 36-character strings. These strings are composed of 32 hexadecimal characters broken up into five groupings separated by '-'s. The first grouping has 8 hex characters, the second through fourth groupings have four hex characters each, and the fifth and final grouping has 12 hex characters.

A value of zero indicates that the base volume name is unique on a controller. A value greater than zero indicates that the volume's base name is used by two or more volumes on the same controller, and that appending '(n)' to this volume's name uniquely identifies it on that controller. A value of -1 indicates that the name ordinal has not yet been determined. Attributes: non-creatable, non-modifiable
owning-vserver-name		string optional	The name of the Vserver that owns this volume. Attributes: key, non-creatable, non-modifiable
owning-vserver-uuid		uuid optional	The 128-bit universally-unique identifier for the vserver that currently owns this volume. Attributes: non-creatable, non-modifiable
provenance-uuid		uuid optional	Universal unique identifier (UUID) for the volume that is used to identify the source volume in a mirroring relationship. When the mirroring relationship is broken, a volume's Instance UUID and Provenance UUID are made identical. An unmirrored volume's Provenance UUID is the same as its Instance UUID. This field is valid for flexible volumes only. UUIDs are formatted as 36-character strings. These strings are composed of 32 hexadecimal characters broken up into five groupings separated by '-'s. The first grouping has 8 hex characters, the second through fourth groupings have four hex characters each, and the fifth and final grouping has 12 hex characters.

As a result, snapshot create operation is temporary disabled on this mirror until the current transfer session finishes. This field is set to true at the start of a SnapMirror transfer session and set to false at the end of that session. Attributes: non-creatable, non-modifiable
redirect-snapshot-id	[0..255]	integer optional	If the volume is a logical mirror destination or is in the process of being made one, this field indicates the logical-id of the snapshot to which clients are to be redirected. If modifiable, when setting this attribute, invalid snapshot id or a non-existent snapshot id specified will be rejected with error ESNAPSHOTDOESNOTEXIST. Failure to set ('stamp') the attribute in the volume will cause error ESTAMPREDIRECTSNAPIDERROR to be returned. This field can be set only for online volumes. This option is valid only in Cluster-Mode. The volume can be set to have no redirection snapshot by using a value of 0. This option can be set only for Cluster-Mode volumes participating in a logical-mirror relationship. Setting this field on a Cluster-Mode volume which is not a logical mirror destination (yet) will not have any impact on client access or the volume's behavior. The client access will be impacted with regard to this value only when the volume is converted to a logical-mirror destination. When reading this attribute, the value of 0 indicates volume has no redirection snapshot. The field cannot be interpreted authoritatively if the volume is offline or restricted. Attributes: non-creatable, non-modifiable

Information about performance settings on a volume.

Name	Range	Type	Description
extent-enabled		string optional	If turned on, this field enables extents in the volume. This causes application writes to be written in the volume as a write of a larger group of related data blocks called an extent. The following values are recognized: 'on' ... Perform this optimization on this volume. This option may duplicate blocks from snapshots into the active file system, thereby using additional disk space. Read performance from snapshots will not be changed. 'space_optimized' ... Perform this optimization on this volume, but do not duplicate blocks from snapshots into the active file system, thereby using space conservatively. Read performance from snapshots may be degraded. 'off' ... Don't perform this optimization on this volume. By default, it is set to 'off'. Using extents may help workloads that perform many small random writes followed by a large sequential read. However, using extents may increase the number of disk operations performed on the controller, so this field should only be turned on when applicable. Attributes: non-creatable, modifiable
is-atime-update-enabled		boolean optional	If false, prevent the update of inode access times when a file is read. This value is useful for volumes with extremely high read traffic, since it prevents writes to the inode file for the volume from contending with reads from other files. By default, this value is true. This field should be used carefully.

read-realloc		string optional	Controls whether application reads cause optimization of the layout of parts of a file or LUN after the data has been read from disk and is in the controller's memory. This optimization is only supported for flexible volumes. The following values are recognized: 'on' ... Perform this optimization on this volume. This option may duplicate blocks from snapshots into the active file system, thereby using additional disk space. Read performance from snapshots will not be changed. 'space_optimized' ... Perform this optimization on this volume, but do not duplicated blocks from snapshots into the active file system, thereby using space conservatively. Read performance from snapshots may be degraded. 'off' ... Don't perform this optimization on this volume. By default, it is set to 'off'. Using read reallocation may help workloads that perform a mixture of random writes and large sequential reads. Attributes: non-creatable, modifiable
