Because the LUN-to-device mapping can be different on each system, clvm logical volume
names are globally unique. You cannot create duplicates.
Repeat these steps for each GFS file system.
15. If GFS was previously installed, you may need to rediscover the previous GFS volume by
running these commands:
pvscan
lvscan
vgscan
16. Complete the following steps on each cluster node to verify that all cluster nodes can
access the GFS volumes, mount them, and access files written by other nodes. In the
following steps, VAULT10 is used as the name of the vault.
a. Configure the /etc/fstab file to automatically mount the file system when VTS
restarts. Add a line to the file that is similar to the following:
/dev/gfsvg1/lv1 /VAULT10 gfs defaults 0 0
