Unfortunately, no, other than after the last fsck resulted in the /vz partition no longer mounted.
We are trying to figure out how to get /vz mounted because the system is refusing to allow this mount for some reason.
If it continues we may need to try another device all together but in the current state no data is recoverable, including backups. This is basically the same state as starting over on a fresh VPS with no data.
We know the data exists so we are trying to preserve it instead of starting from scratch.
