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.
So how do you propose getting a uuid or label on a disk in the first place if you can't identify which is which physically? And how do you know which to move when you want the content in some other box?
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.
