Partition ID's and labels should be unique to the node hosting the disk

[khers]

We are attempting to recover files from a dead node by placing its disk in a new node. Unfortunately, the disk controller enumerates it hardware in random order so we cannot guarantee that the disk for this node is the first one present and is booted. This is because the boot partition for both of these disks share a label and a UUID. It won't solve the disk enumeration problem, but having unique UUIDs and labels would at least allow us to easily identify what disk is being used.

@hakasapl what's the right way to handle this?

Not sure it's possible to handle this, if the RAID controller had an HBA mode it would probably work better but I'm not sure there do

You likely can't fix the disk enumeration problem. However, if you can assign a unique ID or label to the disk and partition then you don't need to.
