나는 이전에 포스팅한 적이 있다.질문solsTiCe는 GPT 파티션에서 스왑을 설정하는 방법을 보여주었습니다. 한동안 효과가 있었지만 지금은 다시 문제가 발생합니다. 스왑이 다시 감지되지 않았습니다. 나는 똑같은 조언을 따랐지만 이번에는 작동하지 않습니다. 재부팅 후 마운트를 건너뛸 것인지 묻는 cryptswap 메시지가 나타납니다. 로그인한 후 free스왑이 표시되지 않고 sudo fdisk -l다음 출력이 표시됩니다.

blkid이전 질문과 정확히 동일한 결과가 나오므로 sudo gdisk /dev/sda.
출력은 다음과 /etc/fstab/같습니다:
# /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).

답변1
답을 찾았습니다여기:
/etc/crypttab다음을 포함하도록 변경되었습니다 .
cryptswap /dev/sda9 /dev/urandom swap,cipher=aes-cbc-essiv:sha256,size=256
다음 /etc/fstab을 포함합니다:
cryptswap /dev/sda9 /dev/urandom swap,cipher=aes-cbc-essiv:sha256,size=256
이제 다음 free -m을 보여줍니다:
