[root@gyhredhat root]# fdisk
Usage: fdisk [-l] [-b SSZ] [-u] device
E.g.: fdisk /dev/hda (for the first IDE disk)
or: fdisk /dev/sdc (for the third SCSI disk)
or: fdisk /dev/eda (for the first PS/2 ESDI drive)
or: fdisk /dev/rd/c0d0 or: fdisk /dev/ida/c0d0 (for RAID devices)

Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.
The number of cylinders for this disk is set to 8322.
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)
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

以下是为收集于网络,个人觉得非常不错
1. 检查所有硬盘分区
[root@web home]# fdisk -l

2. 检查新硬盘分区
[root@web root]# fdisk /dev/hdc
The number of cylinders for this disk is set to 9964.
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)
3. 删除老硬盘分区(hdc1,hdc2,hdc5,hdc6)
Command (m for help): d
Partition number (1-6): 6
4. 保存修改信息
Command (m for help): w
The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.
5. 检查保存情况,直到所有老分区都删除
[root@web root]# fdisk -l /dev/hdc

6. 重新创建硬盘分区
[root@web root]# fdisk -l /dev/hdc
Disk /dev/hdc: 81.9 GB, 81964302336 bytes
255 heads, 63 sectors/track, 9964 cylinders

Command (m for help): d
No partition is defined yet!
Command (m for help): n
Command action
e extended
p primary partition (1-4)
7. 选择主分区(?)
p
8. 选择硬盘分区号(hdc1中的1)
Partition number (1-4): 1
9. 选择硬盘分区的第一柱面(从第2个开始,从1开始不安全(?))
First cylinder (1-9964, default 1): 2
10. 选择硬盘分区结束柱面
Last cylinder or +size or +sizeM or +sizeK (2-9964, default 9964): 5000
11. 保存修改信息
Command (m for help): w
The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.
12. 创建hdc2
[root@web root]# fdisk /dev/hdc
The number of cylinders for this disk is set to 9964.
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)
Command (m for help): n
Command action

Partition number (1-4): 2
First cylinder (1-9964, default 1): 5001
Last cylinder or +size or +sizeM or +sizeK (5001-9964, default 9964):
Using default value 9964
Command (m for help): w
The partition table has been altered!
Calling ioctl() to re-read partition table.

16. 增加新硬盘分区表信息
[root@web root]# vi /etc/fstab

/dev/hdc2 /disk2 ext3 defaults 1 1
17. 挂上硬盘
[root@web root]# mount -a
18. 检查所有硬盘mount情况
[root@web root]# df -h
