#最后别忘了保存!如果你须要的话!
#扩展分区不能直接使用，逻辑分区只能建立在扩展分区上!
第二步：mkfs(mkfs时分区的格式最好与fdisk设定的分区格式一致，不然.......)
mkfs支持ext2 ext3 vfa msdos jfs reiserfs等文件系统。
用法1：mkfs -t
例： mkfs -t ext3 /dev/sdb2
用法2：mkfs.
例：mkfs,vfat /dev/sdb3
mke2fs支持ext2/ext3文件系统
用法：mke2fs [-j]
例:mke2fs -j /dev/sdb5
# 更多更具体的用法请参照相关命令的man手册
下面，接着实验：
例一
[root@novice ~]# mkfs -t ext3 /dev/sdb1
mke2fs 1.41.12 (17-May-2010)
Filesystem label=
OS type: Linux
Block size=1024 (log=0)
Fragment size=1024 (log=0)
Stride=0 blocks, Stripe width=0 blocks
12824 inodes, 51200 blocks
2560 blocks (5.00%) reserved for the super user
First data block=1
Maximum filesystem blocks=52428800
7 block groups
8192 blocks per group, 8192 fragments per group
1832 inodes per group
Superblock backups stored on blocks:
8193, 24577, 40961
Writing inode tables: done
Creating journal (4096 blocks): done
Writing superblocks and filesystem accounting information: done
This filesystem will be automatically checked every 34 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.

Linux如何格式化磁盘?。?/h2>磁盘虽然分好区了，但是还不能用，还需要在这每一个分区上格式化，所谓格式化，其实就是安装文件系统， Windows下的文件系统有Fat32、NTFS ， CentOS使用的文件系统为ext，之前centOS5版本使用ext3作为默认的文件系统，而CentOS6使用ext4作为默认的文件系统。
当用man查询这四个命令的帮助文档时，你会发现我们看到了同一个帮助文档，这说明四个命令是一样的。
