硬盘删除后centos出错处理
一台机器centos6.4在新增加一个硬盘后，重新加载光纤卡后，可以正常显示。再将这块硬盘删除后使用命令：pvs与vgs报错：
[root@mongodb-back host2]# pvscan

google后找到处理方案
#####
Use lsscsi to determine which device is being used (you may need to install the program) then run lsscsi:

# lsscsi
[1:0:0:0] cd/dvd NECVMWar VMware IDE CDR10 1.00 /dev/sr0
[2:0:0:0] disk VMware Virtual disk 1.0 /dev/sda
[2:0:1:0] disk VMware Virtual disk 1.0 /dev/sdb <== the removed physical disk
[2:0:2:0] disk VMware Virtual disk 1.0 /dev/sdc
Now write the delete file with

# echo 1 > /sys/class/scsi_device/2:0:1:0/device/delete
The device is immediately gone.

###
处理后正常！

以下是实际做的步骤：
