Linux VPS新硬盘分区与挂载教程

通过fdisk -l我们可以看到/dev/xvdb(此名称因系统而异)容量有23.6G，而且没有分区，接下来我们对它进行分区和挂载，(按照如下方式挂载，重装系统不丢失挂载分区硬盘的数据)

注： 挂载硬盘过程请按照下面代码“蓝色”标记复制执行既可，不同Linux系统，只需途径名称修改对应系统名称。

fdisk -l

[root@MyVPS ~]#
fdisk -l
Disk /dev/xvda: 8589 MB, 8589934592 bytes

255 heads, 63 sectors/track, 1044 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System

/dev/xvda1 * 1 13 104391 83 Linux

/dev/xvda2 14 1044 8281507+ 8e Linux LVM

Disk /dev/xvdb: 23.6 GB, 23622320128 bytes

255 heads, 63 sectors/track, 2871 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

对/dev/xvdb(此名称因系统而异)进行分区：


fdisk /dev/xvdb

[root@MyVPS ~]#
fdisk /dev/xvdb

The number of cylinders for this disk is set to 2871.

There is nothing wrong with that, but this is larger than 1024,

and could in certain setups cause problems with:

1) software that runs at boot time (e.g., old versions of LILO)

2) booting and partitioning software from other OSs

(e.g., DOS FDISK, OS/2 FDISK)

输入n新建分区

Command (m for help):
n
Command action

e extended

p primary partition (1-4)

p

/dev/xvdb中第1个分区

Partition number (1-4):
1
（输入1后请连续按回车键 Enter/2次）

First cylinder (1-2871, default 1):

Using default value 1

Last cylinder or +size or +sizeM or +sizeK (1-2871, default 2871):

Using default value 2871

输入W保存退出

Command (m for help):
w

The partition table has been altered!

Calling ioctl() to re-read partition table.

将新分区xvdb1(此名称因系统而异)格式化为ext3格式

mkfs -t ext3 /dev/xvdb1

[root@MyVPS ~]#
mkfs -t ext3 /dev/xvdb1
mke2fs 1.39 (29-May-2006)

Filesystem label=

OS type: Linux

Block size=4096 (log=2)

Fragment size=4096 (log=2)

288265 blocks (5.00%) reserved for the super user

First data block=0

Maximum filesystem blocks=4294967296

32768 blocks per group, 32768 fragments per group

Superblock backups stored on blocks:

Writing inode tables: done

Creating journal (32768 blocks): done

Writing superblocks and filesystem accounting information: done

This filesystem will be automatically checked every 24 mounts or

180 days, whichever comes first. Use tune2fs -c or -i to override.

我们示范将新分区xvdb1挂载到目录/home1
新建目录/home1，然后挂载


mkdir /home1

mount /dev/xvdb1 /home1

完成后我们通过df -hal可以看到，新分区已经挂载到目录/home1上了


[root@MyVPS ~]#
df -hal
Filesystem Size Used Avail Use% Mounted on

/dev/mapper/VolGroup00-LogVol00

proc 0 0 0 - /proc

sysfs 0 0 0 - /sys

devpts 0 0 0 - /dev/pts

tmpfs 256M 0 256M 0% /dev/shm

sunrpc 0 0 0 - /var/lib/nfs/rpc_pipefs

/dev/xvdb1 22G 173M 21G 1% /home1

最后添加开机自动挂载：

echo "/dev/xvdb1 /home1 ext3 defaults 1 2" >> /etc/fstab
