I've been trying to setup a 3 server cluster with GFS mounted over iSCSI on
Qemu Virtual Machines. A 4th server acts as a iSCSI Target.
I found and article that explains my issue, but I can't seem to figure out what
the solution is.
QUOTED from : http://kbase.redhat.com/faq/FAQ_51_10923.shtm
After successfully setting up a cluster, cman_tool shows the cluster is
healthy. Mounting the gfs mount on the first node works successfully. However,
when mounting gfs on the second node, the mount command hangs. Writing to a
file on the first node also hangs.
On the second node, the following error is seen in /var/log/messages:
Jul 18 14:49:27 blade3 kernel: Lock_Harness 2.6.9-72.2 (built Apr 24
2007 12:45:55) installed

END QUOTE
My Virtual Machines only have one interface so I still can't figure out why
this is happening. I can successfully mount the GFS partition on any one node
but as soon as I try to start the clvmd on a 2nd node it hangs the whole
cluster. I'm wondering if its a Qemu VM network issue? Each host can ping each
other by name and ip. The cluster works fine but I cant get GFS to work on th
VMs. Is it possible to debug the clvmd to see what IP Address it is sending?
Thanks,
Tracey Flanders
