Here's part of /etc/mdadm.conf
ARRAY /dev/md/root metadata=1.2 name=<server>:root
UUID=7dea42fa:c9ef035d:0a6bada5:3ba5c21f
ARRAY /dev/md/export_1 metadata=1.2 name=<server>:export_1
UUID=637ef224:91b445d8:69d48980:adc8bc70

and, from /etc/fstab, the same drives
/dev/mapper/luks-5e007234-cd4c-47c6-b305-734f353a4405 /                   
   xfs     defaults,x-systemd.device-timeout=0 0 0
/dev/mapper/luks-3da4ae38-b78a-4fb4-9c2d-b029a9b16378 /export/1 xfs
defaults 0 0

excerpt the last luks doesn't exist. They *both* say UUID, so it's *so*
simple to understand (NOT). I got the mdraid UUID from mdadm --examine
--scan.
