As AES-256 partitions using either a block file device or a physical partition cannot be mounted automatically at boot, they will not be automatically checked.
To manually run a fsck:
- Unmount the partition
- Setup loop device:
losetup -e aes-256 /dev/loop0 /dev/sdaX
(use loop1, loop2 etc if the others are being used)
- Enter encryption password
The losetup will not give an error if the password was incorrect. Therefore a test is needed to confirm that the password was entered correctly – mount then umount the loop device:
mount /dev/loop0 /tmp/test
If the device could not be mounted, run:
losetup -d /dev/loop0 and try again.
Execute the fsck:
fsck.ext3 -f /dev/loop0
After running the fsck, delete the loop device:
losetup -d /dev/loop0 and mount the partition like usual.
