[Ocfs2-users] Problems mounting shared filesystem

We are testing clustering and I am having issues getting all of my nodes to
mount. I have 4 nodes. I am using iSCSI to share 1 target with 2 luns.
All 4 nodes can are accessing the target; I can run fdisk -l against the
block devices. Initially I had all 4 nodes mounting the share but brought
the cluster down to add an additional NIC. Presently nodes 2 and 3 can
mount the shares, 1 and 4 can not. Previously I had node 1 mounted and
nodes 2, 3 and 4 could not.
Any help is appreciated!
Nodes 2 & 3:
# service o2cb status

Filesystem "configfs": Mounted
Driver for "ocfs2_dlmfs": Loaded
Filesystem "ocfs2_dlmfs": Mounted
