Failed to stop array: device or resource busy RAID/DMCrypt


Hi,

I've set up encryption using dmcrypt/luks on my /dev/md0 which is a RAID0 array.

It seems I'm running into issues when I do a reboot or halt in that it doesn't stop the array properly. I never had this issue until I encrypted the disks.

/dev/md0 is just three disks which are used as a backup store - no root, boot or swap on these.

/var/log/rc.log:

Code:
1340  [ ok ]
1341  * Shutting down RAID devices (mdadm) ...
1342 mdadm: stopped /dev/md1
1343 mdadm: failed to stop array /dev/md0: Device or resource busy
1344 Perhaps a running process, mounted filesystem or active volume group?
1345  [ !! ]
1346  * ERROR: mdraid failed to stop
1347  * Removing dm-crypt mappings
1348  *   crypt_backup ...
1349  [ ok ]
1350  *   crypt_md0 ...
1351  [ ok ]
Note: I'm not using dmraid here.

Should the RAID devices not be stopped after the dm-crypt mappings are removed? If so, how do you change that order?
