想要将交换文件链接到 LUKS 加密驱动器上的 RESUME 变量吗？| 乌班图21.10

Question

我想在 LUKS 加密文件系统上拥有 32GB 的 SWAP 并启用休眠功能。我的基本交换分区是 1GB，我已将 \xc2\xb4/swapfile\' 设为 31GB。我首先尝试使用此处fallocate解释的命令。我将我的和编辑为：/etc/initramfs-tools/conf.d/resume/etc/default/grub

\n

> cat /etc/initramfs-tools/conf.d/resume \nRESUME=UUID=<uuid> resume_offset=<offset>\n

\n

其中 和 是命令的结果：

\n

> sudo findmnt -no UUID -T /swapfile\n> sudo filefrag -v /swapfile | awk \'{ if($1=="0:"){print substr($4, 1, length($4)-2)} }\'\n

\n

我打电话sudo update-grub并sudo update-initramfs -u。它不起作用。

\n

比我尝试使用命令删除旧的/swapfile并创建新的。dd

\n

> sudo dd if=/dev/zero of=/swapfile bs=1024 count=32768k\n33554432+0 records in\n33554432+0 records out\n34359738368 bytes (34 GB, 32 GiB) copied, 69,0213 s, 498 MB/s\n> sudo mkswap /swapfile \nmkswap: /swapfile: insecure permissions 0644, 0600 suggested.\nSetting up swapspace version 1, size = 32 GiB (34359734272 bytes)\nno label, UUID=b86d678c-9717-44a0-876d-6ee9e26f3685\n> sudo chmod 0600 /swapfile \n> sudo swapon -a\n

\n

比我使用上面的 UUID 并再次编辑/etc/initramfs-tools/conf.d/resume，/etc/default/grub然后调用\nsudo update-grub和sudo update-initramfs -u。以下是一些输出：

\n

> cat /etc/initramfs-tools/conf.d/resume \nRESUME=UUID=b86d678c-9717-44a0-876d-6ee9e26f3685\n> sudo update-initramfs -u\nupdate-initramfs: Generating /boot/initrd.img-5.13.0-22-generic\ncryptsetup: ERROR: Couldn\'t resolve device \n    UUID=b86d678c-9717-44a0-876d-6ee9e26f3685\nW: initramfs-tools configuration sets RESUME=UUID=ea58698b-f7ec-425a-950f-f5e5bae157ce\nW: but no matching swap device is available.\nI: The initramfs will attempt to resume from /dev/dm-2\nI: (/dev/mapper/vgubuntu-swap_1)\nI: Set the RESUME variable to override this.\n

\n

我也尝试/etc/fstab过从/swapfileto更改条目UUID，但没有成功

我在 grub 和 initramfs-tools 中尝试了文件偏移量和驱动器 UUID 的各种组合。我什至尝试简单地重新启动并希望它能起作用。我不知道下一步该做什么。有人有解决方案吗？
