無法刪除卷組
我在 vgroup lvm 中有一個失去的設備。我想刪除 lvm 組。
我做了
# vgremove lvm --force WARNING: Device for PV 6bVVia-tsco-GEyq-1zHZ-Vn8W-Eg0v-MNZMmG not found or rejected by a filter. Aborting vg_write: No metadata areas to write to!

任何想法刪除vg?
如果元數據區域像我的情況一樣為零,則不能使用
--removemissing
或強制刪除 VG。從文件製作塊設備並包含在
$VG
:dd if=/dev/zero of=/tmp/tmp.raw bs=1M count=100 losetup -f losetup /dev/loop0 /tmp/tmp.raw vgextend $VG /dev/loop0
之後我有
Metadata Areas 1
vgremove --force $VG
並刪除 pvdevice:
pvremove /dev/loop0
先跑
vgreduce --removemissing $VG
。這將刪除所有“部分”LV——即使用失去磁碟的任何 LV。男人:vgreduce(8)。
