>hm, /me fails to see the relation to loop-aes here. If I 'dd' to a file that is NOT set up with losetup I do not get the error. >at what stage did the error occur? dd if=/dev/zero of=/dev/loop1 bs=4k conv=notrunc 2>/dev/null >is this reproducible in any way? Every time I try the above. But if I do _not_ perform the below command, it does not happen. head -c 15 /dev/urandom | uuencode -m - | head -n 2 | tail -n 1 | losetup -p 0 -e AES256 /dev/loop3 /dev/md4 If this means the problem is still unrelated to loop-aes, ill take my inquiries elsewhere :) - Linux-crypto: cryptography in and on the Linux system Archive: http://mail.nl.linux.org/linux-crypto/
