NFS mounts query
We have 2 servers in cluster. Node1 has an ext3 mount for backups and the other connects using NFS to this node1.
I believe the reason it is configured in this manner is to not duplicate backups since this is a Database server. Not sure this was the reason though. Right now if node1 goes down all backups fail and they are not accessible.
I believe we can share this backup folder if it is presented from the SAN side to both nodes. But this will cause duplication of information. Any idea how to proceed.

NAME
mounted.ocfs2 - Detects all OCFS2 volumes on a system.
SYNOPSIS
mounted.ocfs2 [-d] [-f] [device]
DESCRIPTION
mounted.ocfs2 is used to detect OCFS2 volume(s) on a system. This tool assumes that the nodes detected on the system are part of the same
cluster as the one specified in /etc/ocfs2/cluster.conf.
OPTIONS
-d Lists the OCFS2 volumes along with their labels and uuids. If a device is not specified, it scans all the devices in /proc/parti-
tions.
-f Lists the OCFS2 volumes along with the list of nodes that have mounted the volume. The node names are listed if the O2CB cluster is
online. Note: As this information is gathered using dirty-read, the information may be stale.
EXAMPLES
[root@node1 ~]# mounted.ocfs2 -d
Device FS UUID Label
/dev/sdb1 ocfs2 26d5dcdf-6d87-45a7-b01a-b98a7791bd61 logs_0405
[root@node1 ~]# mounted.ocfs2 -f
Device FS Nodes
/dev/sdb1 ocfs2 node15, node1
