This type of issue is why relying on /dev/sdX is bad. Mounting based on uuid or label when available is best. Unfortunately, there are controller cards that present all disks as the same uuid. It makes using mdadm that can only see /dev/sdX a pain to use.

When I build, our PXEboot ks partitions and labels the partitions. When I add or replace, I make the partition, the fs, and e2label them. I've gotten to really appreciate labeling. I hate the UUIDs - they're ludicrously too long, and bear no relationship to what device they are, or where they go.
What happens when you move the disks around among machines? Or don't you ever do that after they contain data?
Other than offline backups, we don't move disks, other than to replace.
