I'm trying to achieve full disk encryption using LUKS on both internal hard drivers but during boot system asks for passphrase multiple times. I also tried key file method but initramfs cant find this key file. I also noticed that every time i update grub there are two cryptomount lines in grub.cfg` (for both hard drives) How do i configure that system will ask for passphrase only once for /dev/nvme0n1p2 and then automatically opens second hard drive.

setup

Would you recommend me better setup?

/etc/fstab

/dev/mapper/vg-swap none            swap    sw              0       0

/etc/crypttab

nvmecrypt UUID=c73094a5-8fd0-42c8-86a2-59d05696a94e none luks,discard
hddcrypt  UUID=a0013d72-5a3f-4c17-b072-2feb0bb4ad3f none luks

/etc/crypttab (using key file)

nvmecrypt UUID=c73094a5-8fd0-42c8-86a2-59d05696a94e /root/.keyfile luks,discard,keyscript=/bin/cat
