我有一个带有 3 个驱动器池的家庭服务器，并且操作系统安装在拇指驱动器中，该拇指驱动器出现物理错误，我不得不重新安装操作系统，拇指驱动器崩溃后 LVM 池运行良好，但我意外地选择了其中一个驱动器来手动安装 grub，然后就出错了。
我不知道这个驱动器是如何/为何脱离池的，LV 停止工作。我尝试了几个月，并遵循了不同的指南和说明，我部分恢复了池，但它仍然无法工作。
我现在所知道的有关错误原因的唯一线索是：

答案1
您似乎破坏了 sdb 上的分区表。根据 lvm 的说法，它最初有一个分区占据了整个磁盘，现在 sdb1 太小了，而且现在很多空间都未分配，或者分配给了另一个分区，该分区显示它被 lvm 使用，但 lvm 说它没有使用。您应该能够使用parted删除磁盘上的所有分区，然后重新创建单个完整的磁盘分区来修复此问题。
sudo parted /dev/sdb
rm 5
rm 2
rm 1
mkpart primary ext2 2048s 100%
quit
