Hi,

I’m setting up a 2 node cluster using GFS on a SAN and
everything is ok until one node is forcibly shutdown.  The shutdown is done
for testing the failover process. Initially it the service and resources fails
over on the other node but once node 1 shutdowns and tries to umount the FS the
active node 2 FS suddenly hangs. here’s the output using the group_tool
command.
