[ovirt-users] Re: Cannot restart ovirt after massive failure.
Hello,
Many thanks again for taking the time to try and help me recover this
machine (even though it would have been far easier to simply redeploy it...)

Did you try to search the net/list archives?
Yes. All of them seem to repeat the same clean-metadata command (which
fails).

Yes, see e.g.:
https://lists.ovirt.org/pipermail/users/2016-April/072676.html
As an alternative to the 'find' command there, you can also find the IDs
with:
$ grep metadata /etc/ovirt-hosted-engine/hosted-engine.conf

Yippie! Success (At least it seems that way...)
Following https://lists.ovirt.org/pipermail/users/2016-April/072676.html,
I stopped the broker and agent services, archived the existing hosted
metadata files, created an empty 1GB metadata file using dd, (dd
if=/dev/zero of=/run/vdsm/storage/<uuid>/<uuid> bs=1M count=1024), making
double sure permissions (0660 / 0644), owner (vdsm:kvm) and SELinux labels
(restorecon, just incase) stay the same.
Let everything settle down.
Restarted the services....
... and everything is up again :)
I plan to let the engine run overnight with zero VMs (making sure all
backups are fully up-to-date).
Once done, I'll return to normal (until I replace this setup with a normal
multi-node setup).
Many thanks again!
