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.
