resizing knoppix-data.img

[kl522]

But if the persistent image is encrypted I think the only way to get a larger persistent image is to create a new persistent image and copy the data from the old filesystem to the new one.

This is a very old thread, I thought I just want to post a follow up to this :-

To increase the size of an encrypted image, the following can be done :-

# dd if=/dev/zero bs=1M count=100 >> knoppix-data.aes
( same as the non-encrypted one )
# echo 'password' | losetup -e aes -p 0 /dev/loop6 knoppix-data.aes
( Now you can use /dev/loop6 for your resizing purposes )
# e2fsck -fy /dev/loop6
# resize2fs /dev/loop6
Once you are done, destroy the loop device association of knoppix-data.aes :-
# losetup -d /dev/loop6

Cheers
