Dotaz: dm-crypt/LUKS failed code 22

[martin knocik]

Mam archlinux. Chcel som si na staršom 200 GB sata disku( /dev/sdb ) vytvoriť 1 sifrovanú partíciu. Zmazal som povodné partície na disku a vytvoril 1 ext4 partíciu. Ked som zadal

cryptsetup -v -c aes-xts-plaintext -y -s 512 -h sha512 luksFormat /dev/sdb1

WARNING!

========

This will overwrite data on /dev/sdb1 irrevocably.

Are you sure? (Type uppercase yes): yes

Command failed with code 22: Neprípustný argument

Neviete mi poradiť čo som spravil zle ? ďakujem za pomoc.

Failed to setup dm-crypt key mapping for device /dev/sdb1.

Check that kernel supports aes-xts-plaintext cipher (check syslog for more info).

Command failed with code 5: Failed to setup dm-crypt key mapping for device /dev/sdb1.

Check that kernel supports aes-xts-plaintext cipher (check syslog for more info).

Neviete čo s tým ? Kde a ako mam skontrolovať syslog ?

Ahoj, vypada to, ze nemas posporu pro aes-xts-plaintext sifru. Zkus to takhle:

cryptsetup —verbose —verify-passphrase luksFormat /dev/sdb1

[martin knocik]

cryptsetup --verbose --verify-passphrase luksFormat /dev/sdb1

cyptsetup luksOpen /dev/sdb1 crypto
(mkfs.ext3 /dev/mapper/crypto)
mount /dev/mapper/crypto /mnt/crypto

...

umount /dev/mapper/crypto
cryptsetup luksClose /dev/mapper/crypto
