Linux挂载LVM分区的方法

#fdisk -l

[root@localhost /]# fdisk -l

/dev/sdb1 lvm2 -- 68.36G 68.36G

/dev/sdc2 VolGroup00 lvm2 a- 34.06G 32.00M

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
