Hi Duncan,
Thanks for the info! I've seen that done in the fstab, but it didn't work for me the last time I tried it on the command line. Worth a shot!

Well yeah, if I was mounting all the disks to different mount points, I
would definitely use UUIDs to get them mounted.  But I haven't seen any
way to set up a "mkfs.btrfs" command to use UUID or anything else for
individual drives.  Am I missing something?  I've been doing a lot of
googling.
FWIW, you can use the /dev/disk/by-*/* symlinks (as normally setup by
udev) to reference various devices.

Of course because the identifiers behind by-uuid and by-label are per-
filesystem, those will normally only identify the one device of a multi-
device filesystem, but the by-id links ID on device serials and partition
number, and if you are using GPT partitioning, you have by-partuuid and
(if you set them when setting up the partitions) by-partlabel as well.
