hi guys.
yesterday my raid5 of 4 disk is broken and i dont find a better way as
to re-create it new.
mdadm --create /dev/md2 --assume-clean --verbose --level=5
--raid-devices=4 /dev/sdc1 /dev/sdd1 missing /dev/sdf1
my problem is now that i cannot open die LUKS on the device md2
cryptsetup luksOpen /dev/md2 md2_nas
Device /dev/md2 is not a valid LUKS device.
i found with an hexdump on the disk sdc1 and sdf1 the LUKS header
hexdump -C /dev/sdc1 | head -40
.....
00100000 4c 55 4b 53 ba be 00 01 61 65 73 00 00 00 00 00
|LUKS....aes.....|
....
so i think the header must be also on the md2 device but not on the
beginning.
is my raid constrct false? must i reconstruct my array new?
who can i bring my raid so up that i can open the LUKS and save all my data?
thank you.
