/btrfs is mirrored on both /dev/sdb1 and /dev/sdc1

falidae#  btrfs filesystem show /btrfs 
Label: none  uuid: f77d6ce8-12bf-476a-8276-2031ce3e3c42
        Total devices 2 FS bytes used 978.25GiB
        devid    1 size 1.82TiB used 981.03GiB path /dev/sdb1
        devid    2 size 1.82TiB used 981.03GiB path /dev/sdc1

Thought there was a way to show it was mirrored, can't remember it right
now.

Yes.

Have a vague feeling I may have tried systemd.log_level=debug and it
didn't show anything useful. Not sure  now.

In any case, presumably you want these when it isn't working, so will
try to get it to fail again with the debug option and let you know.
