Screenshot showing palimpsest after system is shutdown and restarted.
1) Array auto started at reboot from /etc/mdadm/mdadm.conf using:
ARRAY /dev/md0 level=raid10 num-devices=4 metadata=01.02 name=ubuntu-
server:0 UUID=c60eb2ea:6a911abf:75743422:12ffb49d
2) Array auto mounted at reboot from /etc/fstab entry:
UUID=23559D7F45CD5191 /media/bliss ntfs rw,utf8 0 0
Note that palimpsest unaware that array is mounted and has read the
/dev/md0 partition table incorrectly (there isn't one, but palimpsest
assumes there is one)
