[Linux-cluster] question about backup/restore of GFS2

[Paras pradhan]

We had a whole cluster lockdown when we forgot to exclude one of the
GFS partitions in netbackup when it was trying to lock the fs when it
the backup started. Then I had to restart one of the nodes. I am still
not sure why the lock was not released.
