I've been trying to configure my gfs cluster to use the fence_sanbox2, and
don't quite have it right. my configuration is pasted below. To test it,
I reboot one of the machines in the cluster, but instead of getting fenced
and the journal replayed, the rest of the cluster just hangs (errors
below). In addition, when I telnet to the fibre switch, the port is not
disabled as I thought it would be. I'm able to use fence_sanbox2 directly
to disable and enable the port. So...does anybody see what I'm doing
wrong? How can I debug this further? Does anything special need to be
done to the init scripts to disable/reenable the port, or does the fenced
take care of that?
I'm using the RHEL4 branch, which I cvs updated a couple weeks back.
