## NAME

> nhcrfsd - Reliable NFS supervisor daemon

## SYNOPSIS

> `/opt/SUNWcgha/sbin/nhcrfsd` [-h] [-v] [-u URL]

## DESCRIPTION

> The `nhcrfsd` daemon manages the Reliable NFS feature of the Foundation Services. The `nhcrfsd` daemon is started when the system comes up (at init level 2). By default, the `nhcrfsd` daemon is monitored by the Daemon Monitor, `nhpmd`(1M).

## OPTIONS

> The following options are supported:

> -h

>   Display help on options and exit.

> -u URL

>   You must specify the URL of the `nhfs.conf` file.

> -v

>   Display the version and the build date of the daemon and exit.

## EXTENDED DESCRIPTION

> You must be logged on as superuser to run the `nhcrfsd` daemon.

> The `nhcrfsd` daemon uses the `nhfs.conf` file and the `/etc/vfstab` file.

> ### The nhfs.conf File

> > The following parameters must be set in the `nhfs.conf` file:

> > - `RNFS.Slice`

> > - `RNFS.StatdAlternatePath`

> > - `RNFS.Share`

> > For more information about these parameters, see the `nhfs.conf`(4) man page.

> ### The /etc/vfstab File

> > Entries in `vfstab` use the syntax described in `vfstab`(4). For each master-eligible node, the `vfstab` entry must contain the following:

> > - Information for mounting Reliable NFS replicated slices so that they can be exported by the NFS server.

> > - Information for mounting the file systems to be replicated by NFS.

> > The following paths are used by applications:

> > - Mount Reliable NFS replicated slices locally (on the master-eligible nodes).

> >   >     /dev/dsk/c0t0d0s3 /dev/rdsk/c0t0d0s3 /export ufs - no logging
> >   >     /dev/dsk/c0t0d0s4 /dev/rdsk/c0t0d0s4 /SUNWcgha/local ufs - no logging

> >   This example mounts the Reliable NFS replicated slice `/dev/rdsk/c0t0d0s3` on `/export` and `/dev/rdsk/c0t0d0s4` on `/SUNWcgha/local/`.

> >   The `RNFS.Share` property allows `/export` to be exported by NFS from the master node.

> > - Mount the Reliable NFS replicated slices by NFS (on the master-eligible nodes).

> >   >     10.28.3.1:/SUNWcgha/local/export - /SUNWcgha/remote nfs - no fg,hard,intr,noac

> >   This example mounts `/SUNWcgha/local/export` of the master node on the `/SUNWcgha/remote` mount point of the master and vice-master nodes.

> > The specified mount options must be selected according to the type of mount entry.

> > You can use the `noac` option if the impact on performance is acceptable. For information about how to enable and disable the `noac` option, see the Netra High Availability Suite Foundation Services 2.1 6/03 Cluster Administration Guide.

## EXIT STATUS

> The exit status for `nhcrfsd` is one of the following:

> 0

>   Daemon started successfully

> 1

>   Daemon failed to start

## ENVIRONMENT VARIABLES

> The `nhcrfsd` daemon uses a catalog of messages in compliance with International Language Environments (I18N) standards. The `NLSPATH` variable must contain the pattern: `/opt/SUNWcgha/lib/locale/%L/LC_MESSAGES/%N`

## FILES

> `/etc/opt/SUNWcgha/nhfs.conf`

>   Configuration and addressing information for the different Foundation Services. The URL for this file could be `file:///etc/opt/SUNWcgha/nhfs.conf`.

> `/opt/SUNWcgha/lib/locale/C/LC_MESSAGES/CRFS.cat`

>   Default catalog of messages

## NOTES

> All `nhcrfsd` daemon messages are logged with the Solaris(TM) `syslog` facility. This facility uses message priorities of the `facility.level` form. The `nhcrfsd` daemon uses the `local0` facility and a level that can be `alert`, `err`, or `info`.

## ATTRIBUTES

> See `attributes`(5) for descriptions of the following attributes:

> ATTRIBUTE TYPE | ATTRIBUTE VALUE
> --- | ---
> Interface Stability | Evolving
> Availability | SUNWnhfsa, SUNWnhfsb

## SEE ALSO

> `nhfs.conf`(4), `nhcrfsadm`(1M), `nhpmd`(1M), and `syslog.conf`(4).
