一、过程步骤
1、#kudzu //检测新硬件，这一步必须！
2、#fdisk -l //查看是否找到新的硬盘，查看硬盘代号。
3、#fdisk /dev/sdb //为新硬盘分区，例如分成sdb1
#mkfs.ext3 /dev/sdb1 //把新硬盘格式化成ext3格式
4、#mkdir /disk2 //创建新的挂载点
5、#mount /dev/sdb1 /disk2/ //手动挂载分区,把硬盘挂到/disk2目录下。
6、#vi /etc/fstab
/dev/sdb1 /disk2 ext3 auto 1 2 //设置为开机自动挂载分区。

查看硬盘代号
[root@AMD-LINUX ~]# fdisk -l
Disk /dev/sda: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders

Disk /dev/sdb doesn’t contain a valid partition table
Disk /dev/dm-0: 9395 MB, 9395240960 bytes
255 heads, 63 sectors/track, 1142 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0×00000000
Disk /dev/dm-0 doesn’t contain a valid partition table
Disk /dev/dm-1: 1073 MB, 1073741824 bytes
255 heads, 63 sectors/track, 130 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0×30307800
Disk /dev/dm-1 doesn’t contain a valid partition table
3、fdisk 分区
[root@AMD-LINUX ~]# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0×623223a1.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won’t be recoverable.
Warning: invalid flag 0×0000 of partition table 4 will be corrected by w(rite)
