[dm-crypt] can't open luks device after raid 5 rebuild

[artificial11000 <artificial11000@googlemail.com>]

Hi guys,

after my encrypted RAID 5 was degraded and rebuilt, I can't open it anymore.

cryptsetup luksOpen /dev/md127 archiv
Geben Sie den Passsatz für /dev/md127 ein:
Kein Schlüssel mit diesem Passsatz verfügbar.

It says that the provided password doesn't match any of the stored keys.

Here's the output of luksDump:
