CAUTION: Once you create the disk group and mount point packages, it is critical that you
administer the cluster with the cfs commands, including cfsdgadm, cfsmntadm, cfsmount,
and cfsumount. If you use the general commands such as mount and umount, it could cause
serious problems, such as writing to the local file system instead of the cluster file system.Any
form of the mount command (for example, mount -o cluster, dbed_chkptmount, or
sfrac_chkptmount) other than cfsmount or cfsumount in a HP Serviceguard Storage
Management Suite environment with CFS should be done with caution. These non-cfs commands
could cause conflicts with subsequent command operations on the file system or Serviceguard
packages. Use of these other forms of mount will not create an appropriate multi-node package
which means that the cluster packages are not aware of the file system changes.
Deleting CFS from the Cluster
Halt the applications that are using CFS file systems.
1. Unmount CFS Mount Points
# cfsumount /cfs/mnt1
# cfsumount /cfs/mnt2
# cfsumount /cfs/mnt3
2. Delete Mount Point Multi-node Package
# cfsmntadm delete /cfs/mnt1
The following output will be generated:
Mount point “/cfs/mnt1” was disassociated from the cluster
# cfsmntadm delete /cfs/mnt2
The following output will be generated:
Mount point “/cfs/mnt2” was disassociated from the cluster
# cfsmntadm delete /cfs/mnt3
The following output will be generated:
Mount point “/cfs/mnt3” was disassociated from the cluster Cleaning
up resource controlling shared disk group “cfsdg1” Shared disk group
“cfsdg1” was disassociated from the cluster.
NOTE: The disk group package is deleted if there is no dependency.
3. Delete Disk Group Multi-node Package
# cfsdgadm delete cfsdg1
The following output will be generated:
Shared disk group “cfsdg1” was disassociated from the cluster.
NOTE: “cfsmntadm delete” also deletes the disk group if there is no dependent package.
To ensure the disk group deletion is complete, use the above command to delete the disk
group package.
4. De-configure CVM
# cfscluster stop
The following output will be generated:
