Also, ensure that we don't try to mount them without root - it appears that it can somehow not error and report that mount was successful when it clearly did not succeed, which can induce this case. We reuse the `--force` flag to indicate that a volume should be removed even after unmount errors. It seems fairly natural to expect that --force will remove a volume that is otherwise presenting problems. Finally, ignore EINVAL on unmount - if the mount point no longer exists our job is done.

at line 174 we do RemoveVolume. Should we return with an error there only if the --force option isn't in play too?

I think we're safe to error there - if removing the volume from the DB fails it's always an error
