Very good.

now i boot my server with a live cd and recreate my raid.
if this was successfully i open the LUKS and check it.
here my commands for this step:
mdadm --create /dev/md2 --assume-clean --verbose --level=5
--raid-devices=4 /dev/sdc1 /dev/sdd1 missing /dev/sdf1
cryptsetup luksOpen /dev/md2 md2_nas
fsck -n /dev/md2

Looks good.
