[ovirt-users] ovirt+gluster+NFS : storage hicups

[Tim Macy]

Nicolas,  I have the same setup dedicated physical system running engine on
CentOS 6.6 three hosts running CentOS 7.1 with Gluster and KVM, and
firewall is disabled on all hosts.  I also followed the same documents to
build my environment so I assume they are very similar.  I have on occasion
had the same errors and have also found that "ctdb rebalanceip <floating
ip>" is the only way to resolve the problem.  I intend to remove ctdb since
it is not needed with the configuration we are running.  CTDB is only
needed for hosted engine on a floating NFS mount, so you should be able
change the gluster storage domain mount paths to "localhost:<name>".  The
only thing that has prevented me from making this change is that my
environment is live with running VM's.  Please let me know if you go this
route.

Thank you,
Tim Macy
