初学者对linux挂硬盘

1、使用root用户执行：

[root@localhost ~]# fdisk -l

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

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          38      305203+  83  Linux
/dev/sda2              39        1048     8112825   83  Linux
/dev/sda3            1049        1305     2064352+  82  Linux swap / Solaris

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

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1        1305    10482381    5  Extended
/dev/sdb5               1        1305    10482349+  82  Linux swap / Solaris

Disk /dev/sdc: 1073 MB, 1073741824 bytes
255 heads, 63 sectors/track, 130 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

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

 

其中Disk /dev/sdc: 1073 MB, 1073741824 bytes 是我们挂的硬盘。

2、

[root@localhost ~]# fdisk /dev/sdc
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.

Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

Command (m for help): n

 

输入n进行新建扩展分区

 

3、

Command action
   e   extended
   p   primary partition (1-4)
e
Partition number (1-4): 1
First cylinder (1-130, default 1):
Using default value 1
Last cylinder or +size or +sizeM or +sizeK (1-130, default 130):
Using default value 130

输入e再输入1，使用默认全部分配给一个分区

4、输入n和l建立逻辑分区

Command (m for help): n
Command action
   l   logical (5 or over)
   p   primary partition (1-4)
l
First cylinder (1-130, default 1): 1
Last cylinder or +size or +sizeM or +sizeK (1-130, default 130):
Using default value 130

 

5、输入p查看分区类型

Command (m for help): p

Disk /dev/sdc: 1073 MB, 1073741824 bytes
255 heads, 63 sectors/track, 130 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sdc1               1         130     1044193+   5  Extended
/dev/sdc5               1         130     1044162   83  Linux

6、输入t转换分区类型

转换为82类型

Command (m for help): t
Partition number (1-5): 5
Hex code (type L to list codes): 82
Changed system type of partition 5 to 82 (Linux swap / Solaris)

Command (m for help): p

Disk /dev/sdc: 1073 MB, 1073741824 bytes
255 heads, 63 sectors/track, 130 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sdc1               1         130     1044193+   5  Extended
/dev/sdc5               1         130     1044162   82  Linux swap / Solaris

7、保存退出

Command (m for help): w
The partition table has been altered!

Calling ioctl() to re-read partition table.
Syncing disks.

8、格式化

[root@localhost ~]# fdisk -l

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

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          38      305203+  83  Linux
/dev/sda2              39        1048     8112825   83  Linux
/dev/sda3            1049        1305     2064352+  82  Linux swap / Solaris

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

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1        1305    10482381    5  Extended
/dev/sdb5               1        1305    10482349+  82  Linux swap / Solaris

Disk /dev/sdc: 1073 MB, 1073741824 bytes
255 heads, 63 sectors/track, 130 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sdc1               1         130     1044193+   5  Extended
/dev/sdc5               1         130     1044162   82  Linux swap / Solaris
[root@localhost ~]# mkfs -t ext3 -c /dev/sdc5
mke2fs 1.39 (29-May-2006)

Checking for bad blocks (read-only test): done                               
Writing inode tables: done                           
Creating journal (4096 blocks): done

180 days, whichever comes first.  Use tune2fs -c or -i to override.

9、挂载到文件夹上

[root@localhost ~]# mkdir /test
[root@localhost ~]# mount /dev/sdc5 /test

 

恭喜你完成将1G的硬盘全部挂载到/test上!!!
