sdc2就是我要挂接的
[root@localhost /]# vgscan
Reading all physical volumes. This may take a while...
Found volume group "VolGroup00" using metadata type lvm2
[root@localhost /]# lvscan
inactive '/dev/VolGroup00/LogVol00' [32.09 GB] inherit
inactive '/dev/VolGroup00/LogVol01' [1.94 GB] inherit
可以看到新修改的VolGroup00是inactive状态
[root@localhost /]# vgchange -a y
2 logical volume(s) in volume group "VolGroup00" now active
[root@localhost /]# lvscan
ACTIVE '/dev/VolGroup00/LogVol00' [32.09 GB] inherit
ACTIVE '/dev/VolGroup00/LogVol01' [1.94 GB] inherit
好了,现在可以挂载了
[root@localhost /]# mount -t ext3 /dev/VolGroup00/LogVol00 /d1
在创建LV时出现的错误
/proc/misc: No entry for device-mapper found Is device-mapper driver missing from kernel?Failure to communicate with kernel device-mapper driver.
解决:modprobe dm-mod
