<tt>Before ocfs2. Can both nodes see the same volume? Does the command
"mounted.ocfs2 -d" on both nodes show the same volume?<br>
<br>
I believe you are using a local disk on rashida1 that rashida2 can't
see.<br>
<br>
For ocfs2 to work, all nodes in the cluster must be able to have full
access to the physical shared disk.<br>

<div>Verified that the two nodes are able to communicate on port 7777.</div>
<div>I formatted a volume /dev/sdb on node rashida1 as ocfs2 with
module type as cluster.</div>
<div>After mounting the volume on local node (rashida1), it is
available on local node, but not visible on the remote node (rashida2).</div>
<div><br>

<div>Node: rashida1</div>

<div>Why is the volume /dev/sdb of rashida1 not visible on node
rashida2?</div>

<div>Request help to resolve this issue.</div>
