问题背景

国产操作系统Euler 21.10，安装Oracle数据库前做磁盘规划发现重名卷组rootvg,无法将空闲物理卷剔除，无空闲空间扩容软件安装目录，ASM磁盘组无空间磁盘可用。

问题现象

执行逻辑卷相关操作全部报错。

经检查发现同名VG、LV ，尝试操作vgreduce报错VG重名，创建新的LV都报错存在重名rootvg。

PV名称为unknown,LV状态为not avaliable。

处理过程

通过vgdisplay、lvdisplay、pvdiskplay发现同名的vg中连系统划分的lv名称也一样，删除相关逻辑卷可能导致操作系统直接hang死。

单独查看异常VG、PV：

尝试通过vguuid重命名报错，需要先删除卷组中的LV：

检查所有LV，有两套系统逻辑分区(最后核查正常的欧拉系统发现是正常分区...)。

尝试格式化多余的逻辑卷分区，因为挂载到home分区无法格式化(该系统当前无应用，可以直接操作，生产慎用)。

lvdisplay 找出转态异常LV的UUID，通过lvuuid删除不可用逻辑卷可行。
