> Volume DB is there per volume keeping all containers metadata in that volume.
> If the DB cannot be opened or read at all, we should fail the volume in the
> volume scan. This means none of the containers can be read. If only part of
> the DB is corrupted and some/most keys can be read, the container scanner
> will mark the corresponding containers as unhealthy. We should not drop the
> whole volume in this case because we may unnecessarily remove healthy copies.
