Ubuntu 10.04挂载CentOS下的LVM

本人电脑有Windows XP和CentOS两个系统,因学习需要装了Ubuntu 10.04,不料发现不能加载lvm,故查阅资料,借鉴别人,整理如下:

1.首先使用vgscan 扫描 lvm 结果如下

zhq@zhq:/$ sudo vgscan
  Reading all physical volumes.  This may take a while...
  Found volume group "VolGroup00" using metadata type lvm2

2.通过 vgdisplay VolGroup00 查看 lvm 的 VG UUID

zhq@zhq:/$ sudo vgdisplay VolGroup00
  --- Volume group ---
  VG Name               VolGroup00
  System ID            
  Format                lvm2
  Metadata Areas        1
  Metadata Sequence No  3
  VG Access             read/write
  VG Status             resizable
  MAX LV                0
  Cur LV                2
  Open LV               0
  Max PV                0
  Cur PV                1
  Act PV                1
  VG Size               19.62 GiB
  PE Size               32.00 MiB
  Total PE              628
  Alloc PE / Size       628 / 19.62 GiB
  Free  PE / Size       0 / 0  
  VG UUID               xPw6Yb-1SYW-ayBT-TqOP-hF4i-w02x-vY0165

3.重命名(本人认为此步可省,可能是源于简洁吧,呵呵,没试,你可以试试,呵呵)

zhq@zhq:/$ sudo vgrename VolGroup00 /dev/vg0
  Volume group "VolGroup00" successfully renamed to "vg0"

这个时候通过 vgdisplay 就可以看到 VG的信息了

zhq@zhq:/$ sudo vgdisplay
  --- Volume group ---
  VG Name               vg0
  System ID           
  Format                lvm2
  Metadata Areas        1
  Metadata Sequence No  4
  VG Access             read/write
  VG Status             resizable
  MAX LV                0
  Cur LV                2
  Open LV               0
  Max PV                0
  Cur PV                1
  Act PV                1
  VG Size               19.62 GiB
  PE Size               32.00 MiB
  Total PE              628
  Alloc PE / Size       628 / 19.62 GiB
  Free  PE / Size       0 / 0 
  VG UUID               xPw6Yb-1SYW-ayBT-TqOP-hF4i-w02x-vY0165

4.激活VG

VG重命名后,默认是非ACTIVE状态,我们要通过以下方式激活VG

zhq@zhq:/$ sudo lvscan
  ACTIVE            '/dev/vg0/LogVol00' [18.16 GiB] inherit
  ACTIVE            '/dev/vg0/LogVol01' [1.47 GiB] inherit


激活 VG
zhq@zhq:/$ sudo vgchange -ay /dev/vg0
  2 logical volume(s) in volume group "vg0" now active


查看状态
zhq@zhq:/$ sudo lvscan

/LogVol00' [18.16 GiB] inherit
  ACTIVE            '/dev/vg0/LogVol01' [1.47 GiB] inherit


zhq@zhq:/$ sudo vgscan
  Reading all physical volumes.  This may take a while...
  Found volume group "vg0" using metadata type lvm2

到此为止,可以在ubuntu下看见久违的centos了,不过/home下的用户进不去,实乃遗憾,说权限不够,改了权限也不行,期待高手指点。
