linux下挂载其他硬盘上lvm分区方法

1.首先使用vgscan 扫描 lvm 结果如下

[root@server /]#  vgscan
  Reading all physical volumes.  This may take a while…
  Found volume group "VolGroup" using metadata type lvm2
  Found volume group "VolGroup" using metadata type lvm2

2.通过 vgdisplay VolGroup 查看 lvm 的 VG UUID

[root@server /]# vgdisplay  VolGroup
  — Volume group —
  VG Name               VolGroup
  System ID
  Format                lvm2
  Metadata Areas        1
  Metadata Sequence No  4
  VG Access             read/write
  VG Status             resizable
  MAX LV                0
  Cur LV                3
  Open LV               2
  Max PV                0
  Cur PV                1
  Act PV                1
  VG Size               111.10 GiB
  PE Size               4.00 MiB
  Total PE              28442
  Alloc PE / Size       28442 / 111.10 GiB
  Free  PE / Size       0 / 0
  VG UUID               utcCcc-3RY9-lIac-pfPe-3LQz-blqV-43QBhP

可以看出当前操作系统使用的VolGroup的 VG UUID 是utcCcc-3RY9-lIac-pfPe-3LQz-blqV-43QBhP

[root@server /]#  pvs
  PV         VG       Fmt  Attr PSize   PFree
  /dev/sda3  VolGroup lvm2 a–  111.10g    0
  /dev/sdb2  VolGroup lvm2 a–  111.30g    0

可以看到vg重名了

然后要改名字

[root@server /]# vgrename iMo92U-YG6l-0BSW-ouMF-yVij-9pXb-VbjZm2 VolGroup01
  Volume group "VolGroup" successfully renamed to "VolGroup01"

[root@server /]# lvscan
  inactive          ‘/dev/VolGroup01/lv_root’ [50.00 GiB] inherit
  ACTIVE            ‘/dev/VolGroup01/lv_home’ [57.53 GiB] inherit
  inactive          ‘/dev/VolGroup01/lv_swap’ [3.77 GiB] inherit
  ACTIVE            ‘/dev/VolGroup/lv_root’ [50.00 GiB] inherit
  inactive          ‘/dev/VolGroup/lv_home’ [57.34 GiB] inherit
  ACTIVE            ‘/dev/VolGroup/lv_swap’ [3.77 GiB] inherit

这样就识别出来了。

激活挂载即可

[root@server /]# vgchange -ay /dev/VolGroup01
  3 logical volume(s) in volume group "VolGroup01" now active
最后mount即可

[root@localhost ~]# mount /dev/VolGroup01/LogVol00 /data/www
