I have a fakeraid created using mdadm on disks /dev/sda and /dev/sdb. After updating to 9.10 I can no longer assemble and mount the raid.

When I try to assemble the raid, this is what happens:

mdadm -A --scan
mdadm: no devices found for /dev/md0

When I try to recreate the array, this is what happens:

mdadm --create /dev/md0 --level 0 --raid-devices=2 /dev/sda /dev/sdb
mdadm: Cannot open /dev/sda: Device or resource busy
mdadm: Cannot open /dev/sdb: Device or resource busy
mdadm: create aborted

I also noticed that ubuntu seems to have detected my raid because it now shows up in computer:/// as a Raid-0 drive. However, when I try to start it up with the gui I get this message:

Failed activating drive: One or more block devices are holding /dev/sda

Thanks for any help
Rex
