探索LV卷丢失的恢复方法

实验的时候想拓展一下LVM空间,重启后用pvdisplay一看pv全部挂掉了,当然就更不用说lv了。最底下的pv是我新加的所以正常。

— NEW Physical volume —

PV Name /dev/sdc6

VG Name

PV Size 23.50 MB

Allocatable NO

PE Size (KByte) 0

Total PE 0

Free PE 0

Allocated PE 0

PV UUID 7vG1NF-QzPj-1JZG-J9xb-tm2M-0gOA-NRIShI

解决:

1.pvcreate –uuid “dsO4dY-tYuc-iFrC-XYi2-WijG-0jZx-vrPUCO” –restorefile /etc/lvm/archive/myvg00000.vg /dev/sdc1

Physical volume “/dev/sdc1” successfully created

2.vgcfgrestore myvg

Restored volume group failed

恢复失败,不知道是什么原因,不知道有人解决过没有?
