我的交换分区既未挂载也未处于活动状态。我的系统确实找到/识别了交换分区，但仅此而已
我的fstab参赛作品：
# /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).
#
# <file system> <mount point> <type> <options> <dump> <pass>
# / was on /dev/sda2 during installation
UUID=13d93751-743e-49f4-9cd4-681aeaa2ba30 / ext4 errors=remount-ro 0 1
# /boot/efi was on /dev/sda1 during installation
UUID=8CB4-46F0 /boot/efi vfat umask=0077 0 1
# /home was on /dev/sda4 during installation
# swap was on /dev/sda3 during installation

我已将最后一个 UUID 手动插入到 fstab 中以访问外部 NTFS 磁盘。这可能是问题所在吗？
根据要求这是我的crypttab：
cryptswap1 UUID=5b41eeb7-0447-491e-b0ce-8f3d35280ea2 /dev/urandom swap,offset=1024,cipher=aes-xts-plain64
这是我的lsblk -f

该命令sudo swapon -a根本没有给我任何输出！
命令ls -lA /dev/mapper显示
