1、查看分区

# fdisk -l  //查看现有硬盘及分区  /dev/sdb就是新的3TB硬盘 。


Disk /dev/sda: 21.4 GB, 21474836480 bytes

255 heads, 63 sectors/track, 2610 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        2610    20860402+  8e  Linux LVM


Disk /dev/sdb: 3324.3 GB, 3324304687104 bytes

255 heads, 63 sectors/track, 404157 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes


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


2、分区
# parted /dev/sdb     //为/dev/sdb硬盘分区

GNU Parted 1.8.1

使用 /dev/sdb

Welcome to GNU Parted! Type 'help' to view a list of commands.

(parted) mklabel gpt     //硬盘转换为GPT

(parted) mkpart     //创建分区

分区名称?  []?     //直接回车

文件系统类型?  [ext2]?      //直接回车,也可以输入ext3或者xfs等格式

起始点? 0   //分区开始

结束点? -1   //分区结束 -1为全部硬盘空间

(parted) p   //查看分区结果


Model: VMware, VMware Virtual S (scsi)

3、格式化
# mkfs -t ext4 /dev/sdb1 

mke2fs 1.39 (29-May-2006)

Filesystem label=

OS type: Linux

Block size=4096 (log=2)

Fragment size=4096 (log=2)

405798912 inodes, 811597575 blocks

40579878 blocks (5.00%) reserved for the super user

First data block=0

Maximum filesystem blocks=0

24768 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 (32768 blocks): done

Writing superblocks and filesystem accounting information: done


This filesystem will be automatically checked every 31 mounts or

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


4、挂载
# mkdir /test   //创建目录 /test。

# mount /dev/sdb1 /test   //把分区挂载到 /test上。

# df -h   //查看已挂载的目录。
