Linux添加新硬盘、分区、格式化、自动挂载

第一步：创建分区

    root# fdisk  /dev/had        à进入到新添加的硬盘中

The number of cylinders for this disk is set to 10402.

There is nothing wrong with that, but this is larger than 1024,

and could in certain setups cause problems with:

1) software that runs at boot time (e.g., old versions of LILO)

2) booting and partitioning software from other OSs

   (e.g., DOS FDISK, OS/2 FDISK)

 

Command (m for help): n           à创建新分区

 Command action

   e   extended

   p   primary partition (1-4)

p                             à创建主分区

Partition number (1-4): 1          à新建的主分区序号

First cylinder (1-10402, default 1):

Using default value 1

Last cylinder or +size or +sizeM or +sizeK (1-10402, default 10402): +500M   à创建主分区大小

 

Command (m for help): w       à保存创建的主分区

第二步：使新创建的分区在系统中立即生效

 root#partprobe

 

第三步：格式化新创建的分区

[root@server ~]# mkfs.ext3 /dev/hda1

mke2fs 1.39 (29-May-2006)

Filesystem label=

OS type: Linux

Block size=1024 (log=0)

Fragment size=1024 (log=0)

122400 inodes, 488848 blocks

24442 blocks (5.00%) reserved for the super user

First data block=1

Maximum filesystem blocks=67633152

60 block groups

8192 blocks per group, 8192 fragments per group

2040 inodes per group

Superblock backups stored on blocks:

        8193, 24577, 40961, 57345, 73729, 204801, 221185, 401409

 

Writing inode tables: done

Creating journal (8192 blocks): done

Writing superblocks and filesystem accounting information: done

 

This filesystem will be automatically checked every 27 mounts or

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

[root@server ~]#

 

第四步：使新创建的分区挂载/mnt/rhce01 目录下

Root#mount /dev/hda1 /mnt/rhce01

 

 

第五步：让挂载在系统重启后仍然有效

root# vim /etc/fstab       à编辑这个文件，添加上下面的一行，使挂载在重启后有效；  

LABEL=/1                /                       ext3    defaults        1 1

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-sda3         swap                    swap    defaults        0 0

/dev/hda1              /mnt/rhce01              ext3    defaults        0 0
