LinuxQuestions.org - 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?
