I'm not sure if this is what he means, but I've assumed that you can not prevent data inconsistencies in databases mirrored by drbd. For instance, You have an atomic transaction that completes on the primary node that writes to multiple blocks While replicating the changes on the secondary, the primary fails The database on the secondary, which may become the primary, will have inconsistent data, right?
