suse11下创建分区，并设置开机自动挂载
步骤（1）查看目前磁盘的状态和使用情况：
linux:~ # fdisk –l
Disk /dev/sda: 2000.4 GB, 2000398934016bytes
255 heads, 63 sectors/track, 243201cylinders
Units = cylinders of 16065 * 512 = 8225280bytes
Disk identifier: 0x0001fa9a
Device Boot Start End Blocks Id System
/dev/sda1 * 1 26108 209712478+ 83 Linux
/dev/sda2 26109 30285 33551752+ 82 Linux swap / Solaris
linux:~ # df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 197G 18G 170G 10% /
devtmpfs 118G 120K 118G 1% /dev
tmpfs 64G 176K 64G 1% /dev/shm
步骤（2）下面在/dev/sda上分一个100G分区出来：
linux:~ # fdisk /dev/sda
The number of cylinders for this disk isset to 243201.
There is nothing wrong with that, but thisis larger than 1024,
and could in certain setups cause problemswith:
1) software that runs at boot time (e.g.,old versions of LILO)
2) booting and partitioning software fromother OSs
(e.g., DOS FDISK, OS/2 FDISK)
Command (m for help): n ——创建新分区
Command action
e extended
p primary partition (1-4)
p ——创建分区类型，e：扩展分区，p：主分区
Partition number (1-4): 3 ——分区编号
First cylinder (30286-243201, default30286): ——‘回车’默认
Using default value 30286
Last cylinder, +cylinders or +size{K,M,G}(30286-243201, default 243201): +100GB ——指定分区大小（点‘回车’后就创建成功了）
Command (m for help): p ——打印分区表，可查看到新建的分区
Disk /dev/sda: 2000.4 GB, 2000398934016bytes
255 heads, 63 sectors/track, 243201cylinders
Units = cylinders of 16065 * 512 = 8225280bytes
Disk identifier: 0x0001fa9a
Device Boot Start End Blocks Id System
/dev/sda1 * 1 26108 209712478+ 83 Linux
/dev/sda2 26109 30285 33551752+ 82 Linux swap / Solaris
/dev/sda3 30286 42444 97667167+ 83 Linux
Command (m for help): w ——写分区表并退出
linux:~ # fdisk -l
Disk /dev/sda: 2000.4 GB, 2000398934016bytes
255 heads, 63 sectors/track, 243201cylinders
Units = cylinders of 16065 * 512 = 8225280bytes
Disk identifier: 0x0001fa9a
Device Boot Start End Blocks Id System
/dev/sda1 * 1 26108 209712478+ 83 Linux
/dev/sda2 26109 30285 33551752+ 82 Linux swap / Solaris
/dev/sda3 30286 42444 97667167+ 83 Linux ——创建成功
补充：如果已经创建了四个主分区，那么再进行分区就会有如下提示：
Command(m for help): n
Youmust delete some partition and add an extended partition first
这样必须先删除一个主分区，然后创建一个扩展分区，这是一个需要注意的地方，在分区规划时，如果要创建的主分区大于四个，那么在创建了三个主分区后，就需要创建一个扩展分区才能满足规划需求。
步骤（3）格式化分区并挂载
按照步骤（2）创建好就进行如下格式化：
linux:~ # mkfs.ext3 /dev/sda3
mke2fs 1.41.9 (22-Aug-2009)
Could not stat /dev/sda3 --- No such fileor directory
The device apparently does not exist; didyou specify it correctly?
报错了？！这个问题有两个解决办法：重启 or不重启——使用partprobe命令，当然还是partprobe命令好使哈，执行如下命令后成功将分区格式化为ext3文件系统
linux:~ # partprobe
linux:~ # mkfs.ext3 /dev/sda3
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
6111232 inodes, 24416791 blocks
1220839 blocks (5.00%) reserved for thesuper user
First data block=0
Maximum filesystem blocks=4294967296
746 block groups
32768 blocks per group, 32768 fragments pergroup
8192 inodes per group
Superblock backups stored on blocks:
32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208,
4096000, 7962624, 11239424, 20480000, 23887872
Writing inode tables: done
Creating journal (32768 blocks): done
Writing superblocks and filesystemaccounting information: done
This filesystem will be automaticallychecked every 29 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.
一切顺利，下面就可以挂载了：
linux:/ # mkdir mynewpt
linux:/ # mount /dev/sda3/mynewpt
linux:/ # df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 197G 18G 170G 10% /
devtmpfs 118G 124K 118G 1% /dev
tmpfs 64G 176K 64G 1% /dev/shm
/dev/sda3 92G 188M 87G 1% /mynewpt ——成功，分区完成
步骤（4）很简单吧，呵呵，不要着急，还有最后一个需要完善的地方。按照上面操作后，盘是分出来了，但是要是重启了系统后，你会发现/dev/sda3没有自动挂载上，这样很麻烦，每次需要自己手动执行mount命令来挂载。需要启动自动挂载的话，只需要修改配置文件：
linux:/ # vi /etc/fstab ——添加如下一行即可：
/dev/sda3 /mynewpt ext3 defaults 0 0
