After reinstallation of my OS, I decide to manually assemble a
# mdadm --assemble --auto=yes --scan=auto /dev/md0
I don't exactly remember a message but program
mdadm return a resizing raid array.
$ more /proc/mdstat
Personalities : [raid6] [raid5] [raid4]
md0 : active raid6 sdc1 sdf1(S) sdh1 sdd1 sdg1 sda1 sdi1 sdb1
4883799680 blocks level 6, 64k chunk, algorithm 2 [7/7] [UUUUUUU]
After I try to run an encryption and:
# cryptsetup luksOpen /dev/md0 md0_crypt
Device /dev/md0 is not a valid LUKS device
I searched but I can't find in Internet how to solve this problem.
This is really bad, because they are a life's fotos/videos... :(
