Linux挂载LVM分区的方法
这几天在折腾服务器 遇到需要挂载第二块硬盘的问题 第二块硬盘做了LVM
经过查找 找到了解决办法 备忘一下
[root@localhost /]# lvscan
inactive '/dev/VolGroup00/LogVol00' [32.09 GB] inherit
inactive '/dev/VolGroup00/LogVol01' [1.94 GB] inherit
发现第二个盘是inactive
无法挂载
#fdisk -l
[root@localhost /]# fdisk -l

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
