ecryptfs-setup-swap 冻结

ecryptfs-setup-swap 冻结

我的电脑开始死机，并显示 cryptswap 尚未准备好的消息，因此我尝试按照本教程操作

http://punygeek.blogspot.de/2012/10/ubuntu-1204-how-to-solve-disk-drive-for.html

一切正常，除了当我运行最后一个命令（加密我的交换）时，它会冻结

ubuntu-gnome@ubuntu-gnome:~$ sudo ecryptfs-setup-swap
WARNING:
An encrypted swap is required to help ensure that encrypted files are not leaked to disk in an unencrypted format.

HOWEVER, THE SWAP ENCRYPTION CONFIGURATION PRODUCED BY THIS PROGRAM WILL BREAK HIBERNATE/RESUME ON THIS SYSTEM!

NOTE: Your suspend/resume capabilities will not be affected.

Do you want to proceed with encrypting your swap? [y/N]: y

INFO: Setting up swap: [/dev/sda5]
WARNING: Commented out your unencrypted swap from /etc/fstab

我尝试在实时 CD 中并通过启动到控制台来运行它，但我仍然得到相同的结果。

我的 crypttab 是空的

我遗漏了什么？为什么 ecryptfs 会冻结？

答案1

当守护程序停止时，会发出消息“cryptdisks stop/waiting”，/etc/init.d/cryptdisks 当尝试重新启动服务时，守护程序就会挂起。

我遇到了同样的问题（在全新安装 Ubuntu 14.10 并运行之后ecryptfs-setup-swap），只不过对我来说，我做过有一个新的条目添加到/etc/crypttab，我做过已将新条目添加至/etc/fstab。

该问题似乎是由于与 UUID 相关的“已知错误”引起的，具体描述如下 使用加密主目录的全新 14.04 安装中交换不起作用

我建议您尝试以下操作：（警告：这些说明假设您的交换分区是/dev/sda5- 如有必要，请进行调整。如果输入错误，您可能会丢失数据。）

  1. 取消注释/etc/fstabfor中的行/dev/mapper/cryptswap1。它应为：

    /dev/mapper/cryptswap1 none swap sw 0 0

  2. 添加以下行到/etc/crypttab：

    cryptswap1 /dev/sda5 /dev/urandom swap,cipher=aes-cbc-essiv:sha256

  3. 然后创建交换空间

    $ sudo mkswap /dev/sda5

  4. 重新启动 cryptdisks 守护进程：

    $ sudo /etc/init.d/cryptdisks stop
cryptdisks stop/waiting # or you may get: Job is not running: cryptdisks
$ sudo /etc/init.d/cryptdisks force-start
 * Starting remaining crypto disks...
 * cryptswap1 (running)...

  5. 检查 crypt 是否正在运行：

    $ sudo cryptsetup status cryptswap1
/dev/mapper/cryptswap1 is active and is in use.

  6. 检查您是否有一些交换空间：

    $ swapon -s

我发现此时交换文件名是 /dev/dm-0。

现在进行全面测试。重新启动，再次检查 cryptswap1 是否仍然处于活动状态，并检查交换空间。这一次，您应该会发现交换空间文件名是 /dev/mapper/cryptswap1。祝你好运！

请注意，该gparted分区将显示为“未知”。
