服务器逻辑卷 /dev/vg0/lv1: read failed after 0 of 4096 at 0: Input/output error

前提:
因云服务器之前使用1000G冗余过大，调整为200G空间

　卸载/dev/vdb1后pvs原先/dev/vg0/lv1错误

[root@ ~]# pvs

　2.查看设备

[root@ ~]#  dmsetup status
data_vg-data_lv: 0 411033600 linear 
vg0-lv1: 0 1992286208 linear 

  3.移除设备

 dmsetup remove --force /dev/vg0/lv1
