有些地方不对劲，我只想恢复vm-或者4-*容器。至少复制一些文件。我对lvm的事一无所知。

我试过了

sudo lvchange -ay -v qubes_dom0/vm-orwell4-private

The output file should either be a block device,
or an existing file.  The file needs to be large
enough to hold the metadata.

Answer 1

当您执行命令时

sudo lvcreate -L 256M -n pool00R qubes_dom0

您创建了一个名为pool00R 00R的逻辑卷。

用这个命令

sudo lvchange -ay qubes_dom0/poool00R

您正在尝试激活一个名为pool00R的逻辑卷(请注意额外的"o")，它并不存在。

作为“答案”的作者，我只能对您表示最深切的歉意:这个额外的"o“对我来说也是看不见的。很抱歉这么晚才发现。
