The newly inserted disks will have a different UUID, and, should we use UUIDs, the operation will require reconfiguring the host to mount the new drives, which is a hassle.You can use filesystem labels, they are easiser to configure on the drives than uuids
I would agree with this. Since the disk being swapped in is defined as a replacement, and so assuming that it will have a new FS built on it, you would add the FS specific option to create a label. For example, if you're creating an ext3 FS, add '-L new-volume-label' to the command line, where the label name is the same as the name used for the original disk.
Your fstab entry would be: LABEL=new-volume-label <mnt pnt> .....usual fstab stuff..... Edit fstab once for all the disks, then every time mkfs is run, with the relevant '-L value', the new disk will mount where the original one did. -- Bob McGowan
