試圖安裝輔助驅動器

美分 6 64 位

嘗試在最近的主驅動器硬碟驅動器故障之前在另一台伺服器上安裝以前使用的備份驅動器。

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

我只想掛載 /dev/sda2 （這是輔助驅動器），但出現上述錯誤。我想把它掛載到 /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

root@server097 [~]# lvscan 
 ACTIVE            '/dev/vg_server097/lv_root' [50.00 GiB] inherit

/dev/sda2是 LVM 組的一部分，您無法掛載它。

您提供的任何其他證據都沒有表明存在另一個磁碟。根據 sda 的所有 LVM 卷/部分已安裝並正在使用/proc/mounts
