用lvreduce命令移除vg00镜像盘时报错： Physical extents on remaining physical volumes are stale...

用lvreduce命令移除vg00镜像盘时报错：

#lvreduce -m 0 /dev/vg00/lvol1

Physical extents on remaining physical volumes are stale or
Remaining physical volumes are not responding.
lvreduce: The LVM device driver failed to reduce mirrors on
the logical volume "/dev/vg00/lvol1".

 

解决办法：

nm_rdb01#[/]lvdisplay -v /dev/vg00/lvol1

 如果PV1 状态为stale, 移除镜像时需要执行：

 

nm_rdb01#[/]lvreduce -m 0 -k /dev/vg00/lvol1 0
Logical volume "/dev/vg00/lvol3" has been successfully reduced.
vgcfgbackup: /etc/lvmtab is out of date with the running kernel:Kernel indicates 3 disks for "/dev/vg00"; /etc/lvmtab has 2 disks.
Cannot proceed with backup.

 

因为"-k" 参数指定出现故障的是0号盘，默认情况下，lvreduce -m 0 /dev/vg00/lvol1移除的镜像逻辑卷位于1号盘。
