Thank you for your help. After more troubleshooting and host reboots, I accidentally discovered that the backing disk on ovirt2 (host) had suffered a failure. On reboot, the raid card refused to see it at all. It said it had cache waiting to be written to disk, and in the end, as it couldn't (wo

I encountered this after upgrading clients to 3.12.9 as well. It’s not present in 3.12.8 or 3.12.6. I’ve added some data I had to that bug, can produce more if needed. Forgot to mention my server cluster is at 3.12.9, and is not showing any problems, it’s just the clients. A test cluster on 3.1
