Good day,

After upgrading to 9.1 my swap partition on my raid array is not detected anymore. So i get dropped in maintenance mode..
I booted with as live CD, and was able to mount md0, but md1 is no where to be found.

when i run mdadm --assemble --scan i get this message:


ubuntu@ubuntu:~$ sudo mdadm --assemble --scan
mdadm: /dev/md0 has been started with 2 drives.
mdadm: no devices found for /dev/md1


/proc/mdstat says this:
ubuntu@ubuntu:~$ sudo cat /proc/mdstat
Personalities : [raid1]
md0 : active raid1 sda1[0] sdb1[1]
234372160 blocks [2/2] [UU]

unused devices: <none>

My /etcmdadm/mdadm.conf says this:
