我在 Ubuntu 上安装了一个 LUKS 分区,其中包含来自 Qubes OS 的这些 lvm 容器:

ubuntu@ubuntu:~$ sudo lvs

出了点问题,我只想恢复 vm-orwell4-* 容器。至少从中复制一些文件。我对 lvm thinpool 一无所知。

我试过

sudo lvchange -ay -v qubes_dom0/vm-orwell4-private
  Activating logical volume qubes_dom0/vm-orwell4-private.
  activation/volume_list configuration setting not defined: Checking only host tags for qubes_dom0/vm-orwell4-private.

  Removing qubes_dom0-pool00_tdata (253:3)

也尝试过

Output file does not exist.
 
The output file should either be a block device,
or an existing file.  The file needs to be large
enough to hold the metadata.
ubuntu@ubuntu:~$ # what? /dev/qubes_dom0 does not even exist
ubuntu@ubuntu:~$ sudo thin_check /dev/qubes_dom0/pool00R

答案1

当你执行命令时

sudo lvcreate -L 256M -n pool00R qubes_dom0

您创建了一个名为的逻辑卷pool00R

使用此命令

sudo lvchange -ay qubes_dom0/poool00R

你试图激活一个名为pool00R(请注意多余的“o”),它不存在。


作为Unix StackExchange 答案首先,我只能向你致以最深切的歉意:那个多余的“o”对我来说也看不见。我很抱歉这么晚才发现。
