[Linux-cluster] Cluster service restarting Locally

We didn't mount multiple nodes to that file system and also the iSCSI
channel is in a separate subnet.

No, but if you mount the file system on more than one node, say "good
bye" to your data.

1.2.28-1 is U6.  U7 will be out soon.  You can contact Red Hat Support
if you want an earlier version.

Another way to make things work a little better for you is to separate
the cluster communication path from the iSCSI path so they're not
contending for the same network.
