I mean the Gluster volume is working fine, but it's really disturbing that I get an error message every 5 minutes. Just to let you know you're not the only one with this problem. I have had it too a couple of times and still don't know the right incantation to get rid of it. I have the same setup: 2 clusters, storage and virt, 2 nodes each, one datacenter.

It might as well be related to a complete shutdown/restart of all machines ( this test setup is not behind a ups which gives some rare opportunities to troubleshoot problems :-) ) Yes, this is a bug I would think. For a gluster only cluster, the storage domain is not relevant. Could you log a bug with the error attached, and we will try to fix this. If it's a simple enough fix, we could backport it to 3.4 Done: https://bugzilla.redhat.com/show_bug.cgi?id=1105513 I used component vdsm, but maybe it should belong to webadmin - I'm a bit unsure which component is responsible for this.

[ovirt-users] Issue / strange behavior with GlusterFS nodes
