Hi Tim,
Nice to read that someone else is fighting with a similar setup :)

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.
Indeed, when I'm stopping/continuing my ctdb services, the main action
is a move of the vIP.
So we agree there is definitively something to dig there!
Either directly, either as a side effect.
I must admit I'd be glad to search further before following the second
part of your answer.
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,
And in a less obvious manner, it also allows to gently remove a host
from the vIP managers pool, before removing it on the gluster layer.
Not a great advantage, but worth mentionning.
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.
I'm more than interested to choose this way, if :
- I find no time to investigate the floating vIP issue
- I can simplify this setup
- This can lead to increased perf
About the master storage domain path, should I use only pure gluster and
completely forget about NFS?
