Re: [Linux-cluster] openais issue



There's a problem with the script that is called by rgmanager to start
the VM, I don't know what causes it

May be you should try something like :

1) stop the VM on all nodes with xm commands
2) edit the /usr/share/cluster/vm.sh script and add the following
lines (after the #!/bin/bash ):
   exec >/tmp/DEBUG 2>&1
   set -x
3) start the VM with clusvcadm -e vm:guest1

It should fail as it did before.

edit the the /tmp/DEBUG file and you will be able to see where it
fails (it may generate a lot of debug)

4) remove the debug lines from /usr/share/cluster/vm.sh

Post the DEBUG file if you're not able to see where it fails.
