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)

Filesystem label=

OS type: Linux

Block size=4096 (log=2)

Fragment size=4096 (log=2)

130560 inodes, 261040 blocks

13052 blocks (5.00%) reserved for the super user

First data block=0

Maximum filesystem blocks=268435456

8 block groups

32768 blocks per group, 32768 fragments per group

16320 inodes per group

Superblock backups stored on blocks:

32768, 98304, 163840, 229376

Checking for bad blocks (read-only test): done

Writing inode tables: done

Creating journal (4096 blocks): done

Writing superblocks and filesystem accounting information: done

This filesystem will be automatically checked every 29 mounts or

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!!!
