1：查看磁盘使用情况
[root@ds ~]# df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sda3             36460452  13764944  20813496  40% /
/dev/sda1               101086     21906     73961  23% /boot
tmpfs                  1017952         0   1017952   0% /dev/shm
/dev/sdb              10321208   2760072   7036848  29% /soft
[root@ds ~]#
2：查看已分区的磁盘
[root@ds ~]# fdisk -l

Disk /dev/sda: 42.9 GB, 42949672960 bytes
255 heads, 63 sectors/track, 5221 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          13      104391   83  Linux
/dev/sda2              14         535     4192965   82  Linux swap / Solaris
/dev/sda3             536        5221    37640295   83  Linux

Disk /dev/sdb: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/sdb doesn't contain a valid partition table

Disk /dev/sdc: 2147 MB, 2147483648 bytes
255 heads, 63 sectors/track, 261 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/sdc doesn't contain a valid partition table
[root@ds ~]#
3：格式化要分区的磁盘 ** sdc
[root@ds ~]# mkfs -t ext3 /dev/sdc
mke2fs 1.39 (29-May-2006)
/dev/sdc is entire device, not just one partition!
Proceed anyway? (y,n) y
Filesystem label=
OS type: Linux
Block size=4096 (log=2)

16 block groups
32768 blocks per group, 32768 fragments per group
16384 inodes per group
Superblock backups stored on blocks:

Writing inode tables: done                            
Creating journal (16384 blocks): done
Writing superblocks and filesystem accounting information: done

This filesystem will be automatically checked every 32 mounts or
180 days, whichever comes first.  Use tune2fs -c or -i to override.
[root@ds ~]#
4：创建挂载点
[root@ds ~]# mkdir /data
[root@ds ~]# ls -l | grep data
drwxr-xr-x 3 root root       4096 Nov 14 13:30 database
5：挂载磁盘
[root@ds ~]# mount /dev/sdc /data
[root@ds ~]# cd /data
[root@ds data]# ls
lost+found
[root@ds data]#
6：设置磁盘自动挂载
[root@ds data]# vi /etc/fstab
LABEL=/                 /                       ext3    defaults        1 1
LABEL=/boot             /boot                   ext3    defaults        1 2
tmpfs                   /dev/shm                tmpfs   defaults        0 0
devpts                  /dev/pts                devpts  gid=5,mode=620  0 0
sysfs                   /sys                    sysfs   defaults        0 0
proc                    /proc                   proc    defaults        0 0
LABEL=SWAP-sda2         swap                    swap    defaults        0 0
/dev/sdb                /soft                   ext3    defaults        0 0
/dev/sdc                /data                   ext3    defaults        0 0
