Dazed and Confused
I obviously don't get it.
I have two 5GB files, /data/data0 and /data/data1. I would like to be
able to mount either, or both
(at the same time) using a cipher. First my problem, then my configuration.
$ /usr/local/sbin/losetup -e aes -k 192 /dev/loop1 /data/data1
$ /usr/local/sbin/mount /mnt/crypt/data1
$ /usr/local/sbin/mount /mnt/crypt/data0
I don't know how it is that I can even mount /data0, because the fstab
file uses loop0 for data0. Anyway,
$ ls /mnt/crypt/data0
data lost+found
Notice, the data directory.
$ /usr/local/sbin/umount /mnt/crypt/data0
$ /usr/local/sbin/umount /mnt/crypt/data1
$ /usr/local/sbin/losetup -d /dev/loop1
$ /usr/local/sbin/losetup -e aes -k 192 /dev/loop0 /data/data0
$ /usr/local/sbin/mount /mnt/crypt/data0
$ ls /mnt/crypt/data0
lost+found
Notice, the data directory is nolonger there!
What the heck is going on? What is the proper way to mount multiple
encrypted files via a loop back?
Here is my configuration.
$ lsmod
