5.2.5. 删除物理卷

如果 LVM 不再使用某个设备，您可以使用 pvremove 命令删除 LVM 标签。执行 pvremove 会将空白物理卷的 LVM 元数据归零。

If the physical volume you want to remove is currently part of a volume group, you must remove it from the volume group with the vgreduce command, as described in 第 5.3.7 节 “从卷组中删除物理卷”.

pvremove /dev/ram15

# pvremove /dev/ram15
  Labels on physical volume "/dev/ram15" successfully wiped
