Great . I will test and let you guys know how it goes. Meanwhile you guys can answer me a question.
a) I have a lun (gfs2) mounted to /test
b) I replicate it
c) I undefine my original lun from this cluster node
d) I now assign the replicated lun to the same cluster node
e) I issue a lip
Since the luns are same in all aspects, will it automatically configure itself the new one and mount it to /test?
Thanks!
Paras.

ordinarily need to change the file system name in the gfs2 superblock.
One way you can do this is something like this:
gfs2_tool sb /dev/device table "your_cluster_name:fs_copy"
If you mean to mount the copy outside the cluster, you could just change
the locking protocol to lock_nolock:
gfs2_tool sb /dev/device proto "lock_nolock"
However, digimer is correct that the commands you did would have wiped out
any existing data.
