Linux XenServer virtual machine expansion LVM disk partition

Description: XenServer installed in the virtual machine, the partition is using the LVM disk partition

requirements: now need to expand the virtual machine root partition/

Specific actions:

First, use Xencenter to increase the disk capacity of the virtual machine, as shown in the following figure

Increase Current disk to 50GB

Note: Must be in the virtual organization machine state

Second, look at the hard disk capacity

Df-h #可以看到此时根分区还是12G, no change.

Fdisk-l #已经可以看到整个磁盘容量变为53 6GB.

Third, create a new disk partition

Fdisk/dev/xvda #对磁盘/dev/xvda to operate

P #查看当前分区

N #创建新分区

4 #创建第四个主分区

T #修改分区类型

8e #输入 8e, using LVM type on behalf of partitions

P #查看当前分区状态

W #保存以上操作, otherwise you cannot create a new partition

After restarting the system, do the following

Iv. Add the newly created partition/dev/xvda4 to the root partition/same LVM

MKFS.EXT3/DEV/XVDA4 #格式化分区, you need to wait a while.

PVCREATE/DEV/XVDA4 #创建一个新的LVM分区

Pvdisplay #查看已经存在的pv (physical volume)

Vgdisplay #查看当前已经存在的vg (Logical Volume Group)

Lvdisplay #查看已经存在的lv (Logical volume)

Vgextend volgroup00/dev/xvda4 #把/dev/xvda4 Join the same VG AS/directory (Logical Volume Group)

Lvextend-l +30.01gb-n/dev/volgroup00/logvol00 #扩容lv (logical volume) LogVol00

E2fsck-f/dev/volgroup00/logvol00 #检查

Resize2fs/dev/volgroup00/logvol00 #生效

Df-h #查看挂载状态, display/partition has been enlarged

at this point, the xenserver virtual machine expands the LVM disk partition complete.
