Thanks,

I think I will go with GlusterFS.   MooseFS looks interesting, but
maintaining a package outside the repo/cloud archive is not something I
want to deal with.

Along the same lines...   is it possible to mount a GlusterFS volume in
pacemaker?  I have tried both ocf:heartbeat:Filesystem and
ocf:redhat:netfs.sh without much luck.   I have managed to get the service
started with upstart though.

Thanks,
Sam
