[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...) > > > > > > Sadly enough, it seems that --clean-metadata requires an active agent. > > E.g. > > $ hosted-engine --clean-metadata > > The hosted engine configuration has not been retrieved from shared storage.

All of them seem to repeat the same clean-metadata command (which fails).

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!
