6:15 a.m.
We had a drive in our NAS fail, but afterwards one of our VM's will not
start.
The boot drive on the VM is (so near as I can tell) the only drive affected.
I confirmed that the disk images (active and snapshot) are both valid with
qemu.
I followed the instructions at
https://www.canarytek.com/2017/07/02/Recover_oVirt_Illegal_Snapshots.html to
identify the snapshot images that were marked "invalid" and marked them as
valid.
update images set imagestatus=1 where imagestatus=4;
