Introduction of hard disk mounting method in Linux Vps/xen system

Xen architecture of the VPS typically not less than 10G (there are also special examples), generally based on the Xensystem panel VPS default Mount 10G hard disk (the first disk), the remaining capacity (the second disk) need to be mounted manually.
1. View the hard drive condition
We use

Fdisk-l

To view the current hard drive condition

"disk/dev/xvdb:32.2 GB" means that the second virtual hard disk has 32.2GB capacity, "/dev/xvda 10.7GB" indicates "/" is currently assigned 10.7MB (on the first virtual disk).


2. Format the disk
General/dev/xvdb (second disk) mounted to Xen system disk, first format second disk

3. New section Tutorial

The code is as follows

Copy Code

Command (M for help): N #新建分区 Command Action E Extended P primary partition (1-4) P #设置为主分区 Partition number (1-4): 1 #主分区号 The cylinder (1-2610, default 1): 1 #开始扇区 (direct return) Using Default value 1 Last cylinder, +cylinders or +size{k,m,g} (1-3916, default 3916): 3916 Using Default value 3916 #结束扇区 (direct default carriage return) Command (M for help): T #指定分区类型 Selected partition 1 #选择1号分区 Hex code (type L to list codes): 8e #8e为LVM Changed system type of partition 1 to 8e (Linux LVM) Command (M for help): W #保存 The partition table has been altered! Calling IOCTL () to re-read partition table. Syncing disks.

4. Reread the partition table

Partprobe
5. View Volume Group

Vgdisplay

The above code shows the current VG details, where you need to record the following: VG Name
6. Create Add Volume Group
Create a new PV and add the/dev/xvdb to the "VG name" listed in the previous command, and the VPS's VG name is VolGroup0064 (check your VG name)

The code is as follows	Copy Code
Pvcreate/dev/xvdb1 Vgextend VOLGROUP0064/DEV/XVDB1

7. View Check Volume group

Lvdisplay

Vgdisplay

View the VG and record the values for free pe/size

8. Add Volume Group table

That is to add the VG of/dev/volgroup0064/logvol101 free pe/size to the/dev/volgroup0064/logvol100.

Lvresize-l +959/dev/volgroup0064/logvol00
Above +959 is the value of vgdisply result free pe/size (figure), also can fill 29.97GB

Here the entire graphics and text tutorial is complete, next will bring you some related hard disk mount tutorial.
Hang after completion you can try restarting the machine to solve other problems
