Hi ,
I have setup a two node cluster in lab, with Vmware Server, and
hence used manual fencing. It includes a iSCSI GFS2 partition and
it service Apache in Active/Passive mode.
Cluster works and I am able to relocate service between nodes with
no issues. However, the problem comes when I shutdown the node,
for testing, which is presently holding the service. When the node
becomes unavailable, service gets relocated and GFS partition gets
mounted on the other node, however it is not accessible. If I try
to do a "ls/du" on GFS partition, the command hangs. On the other
hand the node which was shutdown gets stuck at "unmounting file
system".
I tried using fence_manual -n nodename and then fence_ack_manual
-n nodename, however it still remains the same.
Can someone please help me is what I am doing wrong?
Thanks,

It would be good to see /etc/fstab configuration used on
cluster nodes. If /gfs partition is mounted manually it will not
be unmounted correctly in case you restart node ( and not
executing umount prior restart ), and will hang during
shutdown/reboot process.
