Do You have any experience with using > this configuration? I have configured a 6 disk loop-AES root encrypted server. I made two 3-disk raid5 and one raid0 on top of that and the loop-AES on top of the raid0. Works fine. One problem you did not realize: You will have to enter your password 6 times or modify some script to read it only one time and pass it 6 times to losetup. Therefor it makes more sence to have only as many loop devices as CPUs. If you have dualcore then create two raid5, put loop-AES on top of each and create a raid0 on the two. - Linux-crypto: cryptography in and on the Linux system Archive: http://mail.nl.linux.org/linux-crypto/
