I have a fresh full encrypted installation. Works fine.
I set up an alternate encryption password with
sudo cryptsetup luksAddKey /dev/sda2 -S 2 -i=10 # new passphrase... sudo mkinitcpio -p linux
After a reboot the old passphrase still works, but the new one results in a grub rescue shell with “no such cryptodisk found” error. Did I miss to change sth. else?
Thanks for any hint!
