下面详细介绍Linux下的分区详细步骤，是在虚拟机下测试。

SSG连上系统后运行fdisk -l查看磁盘信息。当前测试的环境运行命令可以看到以下信息：

Disk /dev/vda: 5368 MB, 5368709120 bytes
16 heads, 63 sectors/track, 10402 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x000334aa

Device Boot      Start         End      Blocks   Id  System
/dev/vda1   *           3        1018      512000   83  Linux
Partition 1 does not end on cylinder boundary.
/dev/vda2            1018       10403     4729856   8e  Linux LVM
Partition 2 does not end on cylinder boundary.

Disk /dev/vdb: 10.7 GB, 10737418240 bytes
16 heads, 63 sectors/track, 20805 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x324df647

/dev/vdb即为新加的硬盘，在挂载前需要进行分区，运行fdisk /dev/vdb

Command (m for help):n
Command action
     e  exttended
     p  primary parrtition (1-4)
p
primary parrtition (1-4):1
First cylinder (1-20805,default 1):    "默认为空直接回车
Last cylinder or +sizeG or +sizeM or +sizeK (1-20805, default 20805):20805
Command (m for help):w

此时新加硬盘就已经分区成功了，运行fdisk -l可以查看到：

Disk /dev/vdb: 10.7 GB, 10737418240 bytes
16 heads, 63 sectors/track, 20805 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x324df647

   Device Boot      Start         End      Blocks   Id  System
/dev/vdb1               1       20805    10485688+  83  Linux

/dev/vdb1               1       20805    10485688+  83  Linux
分好区后再对其格式化：mkfs -t ext4 /dev/vdb1
格式化后就可对其挂载:mount /dev/vdb1 /www    (将vdb1分区挂载到www下)
设置开机自动挂载:编辑文件/etc/fstab，添加以下信息保存即可:

/dev/vdb1               /www                    ext4    defaults        0 0

至此就分区好了并已经设置了开机自动挂载。
