Hi all,

As most of you have got hints from previous messages, hosted engine won't work on gluster . A quote from BZ1097639

"Using hosted engine with Gluster backed storage is currently something we really warn against.

I think this bug should be closed or re-targeted at documentation, because there is nothing we can do here. Hosted engine assumes that all writes are atomic and (immediately) available for all hosts in the cluster. Gluster violates those assumptions.

​Until the documentation gets updated, I hope this serves as a useful notice at least to save people some of the headaches I hit like hosted-engine starting up multiple VMs because of above issue.

​

Now my question, does this theory prevent a scenario of perhaps something like a gluster replicated volume being mounted as a glusterfs filesystem and then re-exported as the native kernel NFS share for the hosted-engine to consume? It could then be possible to chuck ctdb in there to provide a last resort failover solution. I have tried myself and suggested it to two people who are running a similar setup. Now using the native kernel NFS server for hosted-engine and they haven't reported as many issues. Curious, could anyone validate my theory on this?
