linux版本为

1、查看主机硬盘划分情况，我们需要在/dev/sdb划分一文件系统，大小在80G左右。
[root@hzmc bin]# fdisk -l
Disk /dev/sda: 154.7 GB, 154750418432 bytes
255 heads, 63 sectors/track, 18814 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/sdb: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/sdb5 3805 7452 29302528+ 83 Linux
/dev/sdb6 7453 7577 1004031 83 Linux
2、在/dev/sdb上划分文件系统
[root@hzmc bin]# fdisk /dev/sdb
The number of cylinders for this disk is set to 60801.
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
First cylinder (7578-60801, default 7578):
Using default value 7578
Last cylinder or +size or +sizeM or +sizeK (7578-60801, default 60801): +81920M
Command (m for help): w
The partition table has been altered!
Calling ioctl() to re-read partition table.
