无法删除卷组

我在 vgroup lvm 中丢失了一个设备。我想删除 lvm 组。

我做到了

# vgremove lvm --force

有什么想法可以删除 vg 吗？

答案1

--removemissing如果元数据区域等于零（就像我的情况一样），则不能使用或强制删除 VG。

从文件创建块设备并包含在$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

之后我Metadata Areas 1

vgremove --force $VG

并删除 pvdevice：

pvremove /dev/loop0

答案2

首先运行vgreduce --removemissing $VG。这将删除所有“部分”LV - 即使用丢失磁盘的任何 LV。Man：vgreduce(8)。
