Veritas Storage Foundation 5.1 SP1 Cluster File System Administrator"s Guide (5900-1738, April 2011)

Actions
■ On each node, a /opt/VRTSvcs/bin/IP/actions/nfscfs file is installed. This
file is used to start and stop the NFS locking daemons on a specified node. The
action script is used instead of using rsh, ssh or hacli for remote command
execution from the triggers.
■ On each node, a /opt/VRTSvcs/bin/ApplicationNone/actions/nfscfsapp
file is installed. This file is used while configuring and unconfiguring the
Clustered NFS solution using cfsshare config and cfsshare unconfig
commands.
cfsshare manual page
This Clustered NFS feature adds a new configuration utility called cfsshare to
the VRTScavf package and several scripts that are added into the VCS
configuration to manage parallel NFS server resources. The cfsshare command
modifies VCS resources that were created by other utilities such as cfsmntadm.
See the cfsshare(1M) manual page.
Configure and unconfigure Clustered NFS
This section describes how to configure and unconfigure Clustered NFS.
Configure Clustered NFS
cfsshare config -p nfs [-n] shared_disk_group shared_volume mount_point
Note: The cfsshare config command fails if the shared_volume specified is
already registered with VCS. Verify that the shared_volume is not registered with
VCS by examining the output from the following command:
# /opt/VRTS/bin/cfsmntadm display
The CNFS solution requires a shared file system such as /locks that is mounted
on all cluster nodes. This file system is not a data file system; it contains the lock
state files corresponding to NFS clients holding locks on the CNFS servers.
Note: If CIFS is already configured on the cluster, then specify the same
shared_volume and mount_point for configuration of Clustered NFS.
