==== remove the degraded raid ====
when you install the smeserver with one drive with a degraded raid, you will see a 'U_' state but without warnings. If you want to leave just one 'U' in the /proc/mdstat and stop all future questions about your degraded raid state, then :
mdadm --grow /dev/md0 --force --raid-devices=1
mdadm --grow /dev/md1 --force --raid-devices=1
after that you will see this
# cat /proc/mdstat
Personalities : [raid1]
md0 : active raid1 sda1[0]

md1 : active raid1 sda2[0]
