# lvdisplay

  /dev/VolGroup1/LVdata1: read failed after 0 of 4096 at 0: Input/output error

  /dev/VolGroup1/LVdata1: read failed after 0 of 4096 at 214744104960: Input/output error

  /dev/VolGroup1/LVdata1: read failed after 0 of 4096 at 214744162304: Input/output error

  /dev/VolGroup1/LVdata1: read failed after 0 of 4096 at 4096: Input/output error

2、查看设备

# ls /dev/VolGroup1 -lh

total 0

lrwxrwxrwx 1 root root 7 Jul 20 09:58 LVdata1 -> ../dm-5

# dmsetup status

VolGroup00-LVtmp: 0 20971520 linear 

VolGroup00-LVhome: 0 1024000 linear 

VolGroup1-LVdata1: 0 419422208 linear 

VolGroup00-LVvar: 0 48685056 linear 

VolGroup00-LVswap: 0 8388608 linear 

VolGroup00-LVroot: 0 46137344 linea

3、移除设备依赖

# dmsetup remove --force VolGroup1-LVdata1

4、为设备重新进行处理
