root@server097 [~]# mount /dev/sda2 /backup
mount: unknown filesystem type 'LVM2_member'

我只想挂载 /dev/sda2（这是辅助驱动器），但出现上述错误。我想将其挂载到 /backup

root@server097 [~]# pvscan
  PV /dev/sda2   VG vg_server097   lvm2 [148.56 GiB / 0    free]
  Total: 1 [148.56 GiB] / in use: 1 [148.56 GiB] / in no VG: 0 [0   ]

root@server097 [~]# vgscan
  Reading all physical volumes.  This may take a while...
  Found volume group "vg_server097" using metadata type lvm2

答案1

/dev/sda2是 LVM 组的一部分，您无法挂载它。

您提供的其他证据表明没有其他磁盘存在。根据/proc/mounts
