Fdisk-l View Current Disk usage

Fdisk/dev/sdb Partitioning

MKFS.EXT4/DEV/SDB1 formatting to a partition

Mkdir/data Creating a Mount Directory

Mount/dev/sdb1/data to mount the newly partitioned partition to the/data directory

Vi/etc/fstab mount the information in the Unload configuration file, boot up the Mount information

/dev/sdb1/data EXT4 Defaults 1 2

Mount-a

Df-h

Experiment

One or one centos6.5 machine with only one piece of 20G hard drive, now need to give new hanging on a 25G hard drive

1, disk information, the hard drive has been mounted on the machine, through the command fdisk-l can see

650) this.width=650; "src=" Http://s2.51cto.com/wyfs02/M02/8B/2C/wKioL1hGd6eBgNxOAAB2dmMoT4I032.png "title=" 1.png " alt= "Wkiol1hgd6ebgnxoaab2dmmot4i032.png"/>

2, FDISK/DEV/SDB to the disk partition 10G space out

650) this.width=650; "src=" Http://s2.51cto.com/wyfs02/M00/8B/2F/wKiom1hGeFyh9sBeAACdb6gnYzs043.png "title=" 2.png " alt= "Wkiom1hgefyh9sbeaacdb6gnyzs043.png"/>

3. Format and mount the/DEV/SDB1 to/data

650) this.width=650; "src=" Http://s2.51cto.com/wyfs02/M01/8B/2C/wKioL1hGeROQpHMyAABhRwtcZ30809.png "title=" 3.png " alt= "Wkiol1hgeroqphmyaabhrwtcz30809.png"/>

4, edit the configuration file, boot to load the hard disk information

[Email protected] ~]# Vi/etc/fstab

/dev/sdb1/data ext4 defaults 1 2

Second, when the/data is not enough, can not be divided into a new partition, and then mounted to the same directory/data, so that the original data can not see, if the new partition is attached to the/data, then we only need to umount-l/dev/sdb2 the new partition SDB2 Uninstall, The original data can be seen.
