Thank you so much for your reply. Do you happen to have a link on how to configure manual fencing?
Thanx!!

GNBD is like iscsi. A regular node with local storage can use gnbd_serv to
act like an iscsi target, exporting the local storage to the network. The
GFS nodes access the storage via the GNBD driver, much like they would using
the iSCSI driver. If you are using GNBD to create shared storage, you use
fence_gnbd to disable access to that shared storage. Since you are using iSCSI
for your shared storeage, you cannot use fence_gnbd to disable access to that
storage. Sorry. You need to use another fencing method.
