I want to store private documents on a dvd so I followed this prescription

umount mnt1
cryptsetup luksClose loop
losetup -d /dev/loop0
growisofs -dvd-compat -Z /dev/dvd=/video_1/loop
This all completed without errors
So then I
cryptsetup luksOpen /dev/dvd dvd
mount -t ext3 -o rw,defaults /dev/mapper/dvd ~/dvd
An "rw" mount for a DVD? No wonder you get problems.
The journal and other data updated (e.g. last-access time
stamp updates) must have piled up in the filesystem buffer.
Umounting requires them to be flushed to disk, which cannto be
done due to non-writability.
Just use the following for mounting the mapped DVD:
mount -t ext3 -o ro /dev/mapper/dvd ~/dvd
That should fix things.

Cut and paste strikes again
