Fedora 9挂载LVM分区方法

在Fedora 9里试图挂载另外一块硬盘,其中的一个分区是LVM2格式的,不能直接:“mount /dev/sdb3 /mnt/sdb3”,查找挂载方法破费了一番周折,记录如下,以备不时之需。

1、pvs

[root@localhost yuanbor]# /sbin/pvs

WARNING: Duplicate VG name VolGroup00: Existing tWwhxK-0M8r-sqhQ-VW7m-0BYv-BPkO-pgBRM8 (created here) takes precedence over 7kU450-LaPn-afEa-iWGw-xiqD-Tmwe-ohpL3f

PV VG Fmt Attr PSize PFree

/dev/sda2 VolGroup00 lvm2 a- 33.97G 32.00M

/dev/sdb3 VolGroup00 lvm2 a- 36.78G 32.00M

这个比较惨,两个VG名字重了,下面将第二个VG修改名字。

2、vgrename

[root@localhost yuanbor]#/sbin/vgrename 7kU450-LaPn-afEa-iWGw-xiqD-Tmwe-ohpL3f /dev/VolGroup01

WARNING: Duplicate VG name VolGroup00: Existing tWwhxK-0M8r-sqhQ-VW7m-0BYv-BPkO-pgBRM8 (created here) takes precedence over 7kU450-LaPn-afEa-iWGw-xiqD-Tmwe-ohpL3f

Volume group “VolGroup00″ successfully renamed to “VolGroup01″

[root@localhost yuanbor]# /sbin/pvs

PV VG Fmt Attr PSize PFree

/dev/sda2 VolGroup00 lvm2 a- 33.97G 32.00M

/dev/sdb3 VolGroup01 lvm2 a- 36.78G 32.00M

3、lvscan

[root@localhost sdb3]# /sbin/lvscan

inactive ‘/dev/VolGroup01/LogVol00′ [34.81 GB] inherit

inactive ‘/dev/VolGroup01/LogVol01′ [1.94 GB] inherit

ACTIVE ‘/dev/VolGroup00/LogVol00′ [32.00 GB] inherit

ACTIVE ‘/dev/VolGroup00/LogVol01′ [1.94 GB] inherit

可以看到新修改的VolGroup01是inactive状态。

4、vgchange

[root@localhost sdb3]# /sbin/vgchange -ay /dev/VolGroup01

2 logical volume(s) in volume group “VolGroup01″ now active

[root@localhost mnt]# /sbin/lvscan

ACTIVE ‘/dev/VolGroup01/LogVol00′ [34.81 GB] inherit

ACTIVE ‘/dev/VolGroup01/LogVol01′ [1.94 GB] inherit

ACTIVE ‘/dev/VolGroup00/LogVol00′ [32.00 GB] inherit

ACTIVE ‘/dev/VolGroup00/LogVol01′ [1.94 GB] inherit

好了,现在可以挂载了。

5、mount

[root@localhost mnt]# mount /dev/VolGroup01/LogVol00 /mnt/sdb3
