Oh, I always do. After creating the array as md0 I opened it in Gparted
(GUI) to create and format the partition. If you right-click on the
partition you can get its UUID, which I saved in my text file where I
keep all the junk I had to go through to create the array and mount it.

It's nice to know that you can get the UUID from /dev/disk, but there
is also a command (that I have forgotten) to get the UUID. For a long
time I used LABEL= for mounting, where I had give the partition a
label. Labels are great, but you have to be careful not to label more
than one partition with the same label. I like labels, because they are
human readable, unlike UUIDs.
