A troca não funciona mesmo depois de seguir o conselho anterior

Question

Eu já postei uma pergunta qual solsTiCe me mostrou como configurar uma troca em uma partição GPT. Funcionou por um tempo, mas agora estou tendo problemas novamente. A troca não foi detectada novamente. Eu segui exatamente o mesmo conselho, mas não funciona desta vez. Após a reinicialização, aparece uma mensagem cryptswap perguntando se eu quero pular a montagem, etc. Após o login, free não mostra nenhuma troca, sudo fdisk -l mostra a seguinte saída:

WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.

blkid tem exatamente a mesma saída da pergunta anterior, e o mesmo ocorre com sudo gdisk /dev/sda .

A saída de /etc/fstab/ é:

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).

/dev/mapper/cryptswap        none            swap    defaults        0       0

e /etc/crypttab são:

#cryptswap1 UUID=cfa1562c-1530-4bf6-85c0-babe65ae4e05 /dev/urandom swap,cipher=aes-cbc-essiv:sha256
cryptswap   /dev/sda9    /dev/urandom     swap,cipher=aes-cbc-essiv:sha256,size=256

Encontrou a resposta aqui :

/etc/crypttab alterado para incluir:

cryptswap   /dev/sda9    /dev/urandom     swap,cipher=aes-cbc-essiv:sha256,size=256

e /etc/fstab para incluir:

cryptswap   /dev/sda9    /dev/urandom     swap,cipher=aes-cbc-essiv:sha256,size=256

Agora, free -m mostra:
