Hello all,
Following an advice found in an Internet forum, I am sending this list my request for help in hope someone will be able to answer it.
I am installing Debian in a new computer (so I am pretty flexible about what I can do).
I started following a tutorial for RAID5 + DM-CRYPT + LVM2 and I now face a weird issue.
I launch the computer with the latest Debian live distribution and work on the hard drives from there.
The first steps that concern this issue are:
I partition the 4 hard drives using fsdisk, one partition with 10GB for /boot, one with 130GB for swap, and two big partitions for the operating system and for additional data. /boot is set as bootable, all
as Linux Raid devices (code fd).
I create a RAID5 array with the four hard drives:
# mdadm --create /dev/md3 --level=5 --raid-devices=4 /dev/sda4 /dev/sdb4 /dev/sdc4 /dev/sdd4
Then I format it to ext4:
# mke2fs -t ext4 /dev/md3
Then I encrypt the partition:
# KEYFILE="/media/PENDRIVE/picture.jpg"
# cryptsetup --hash sha512 --key-size 256 --cipher aes-cbc-essiv:sha256 luksFormat /dev/md3 $KEYFILE
WARNING!
========
This will overwrite data on /dev/md3 irrevocably.
Are you sure? (Type uppercase yes): YES

And then I try to open the RAID5 array:
# cryptsetup --key-file $KEYFILE luksOpen /dev/md3 md3encrypted
And I get:
Device /dev/md3 is not a valid LUKS
device.
Can anyone let me know what is happening or what I did wrong?
Thank you in advance,
Lucy
