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?
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
