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.<br>
