The Mount agent has the following notes:
The high availability fire drill detects discrepancies between the VCS configuration and the underlying infrastructure on a node; discrepancies that might prevent a service group from going online on a specific node. For Mount resources, the high availability drill performs the following, it:
For more information about using the high availability fire drill see the Veritas Cluster Server User's Guide.
If the mount option in the mount table output has the option mntlock="key", then it is locked with the key key. To verify if this option has a value of "key", run the mount command and review its output.
If the VxFS file system has "mntlock=key" in its mount options, then unmounting the file system fails.
You can unlock the file system with the fsadm command and then unmount it.
To unlock a lock, you can run the following command where key is the key's name and mount_point_name is the name of the mount point.
# /opt/VRTS/bin/fsadm -o mntunlock="key" mount_point_name
You can run the vxumount command with the option "mntunlock=key", for example:
# /opt/VRTS/bin/vxumount -o mntunlock=key mount_point_name
If you want to use the Mount resource to monitor the ZFS file system, perform the following steps.
Create the tank storage pool and file system on the disk device c1t0d0 for example.
Create the home file system in tank.
Set the value of the MountPoint attribute to legacy.
# zfs set mountpoint=legacy tank/home
Set the Mount agent's attributes. The following is an example of this configuration's main.cf file.
