During a disaster "test" (randomly removing drives), I pulled one osd and one drive that had the journals for 4 other OSDs. So I assumed this would down/out 4 possibly 5 OSDs. Upon re-inserting the drives they were given different /dev/sd[a-z] labels, now the journal disk has the SD[a-z] label that the OSD had and the OSD has the journal. I'm not sure how to prevent this nor fix it. I've searched through the proxmox docs to no avail.
 
Changing /dev/sd[a-z] should not be a problem. If you want to do something with a specific disks it might be better to use their IDs instead.
