Linux disk Create extended partition

Add a disk under Linux (CentOS6.5) to create an extended partition and mount it.

1. Check if the system recognizes the hardware and see that the/dev/sdb disk in the red box has not yet created the partition.

Note: If you do not recognize the need to restart the computer, or turn off the computer restart can be recognized.

#fdisk-L

2. Create an extended partition

#fdisk/dev/sdb

650) this.width=650; "Src=" Http://s5.51cto.com/wyfs02/M02/8A/13/wKioL1gl3GPCbd-iAABvXeCOad4039.png-wh_500x0-wm_3 -wmp_4-s_3938642513.png "title=" Extended partition 2.png "alt=" Wkiol1gl3gpcbd-iaabvxecoad4039.png-wh_50 "/>

3. The extended partition was created successfully, but the extended partition cannot be used directly, and the logical partition on the extended partition will be created if you want to use it.

#fdisk-L

650) this.width=650; "src=" Http://s3.51cto.com/wyfs02/M02/8A/13/wKioL1gl3Sej4z29AABUFpJa4F8620.png "title=" Extended partition 3.png "alt=" Wkiol1gl3sej4z29aabufpja4f8620.png "/>

4. Creating Logical partitions

#fdisk/dev/sdb

650) this.width=650; "src=" Http://s3.51cto.com/wyfs02/M01/8A/17/wKiom1gl3p-AHNrXAABKhK266HY464.png "title=" Extended partition 4.png "alt=" Wkiom1gl3p-ahnrxaabkhk266hy464.png "/>

5. Check to see if the logical partition was created successfully.

#fdisk-L

650) this.width=650; "src=" Http://s1.51cto.com/wyfs02/M01/8A/17/wKiom1gl3zqiwgXEAABXb9rsAjI910.png "title=" Extended partition 5.png "alt=" Wkiom1gl3zqiwgxeaabxb9rsaji910.png "/>

6. After the creation, format the disk, directly enter the command and wait to complete.

# MKFS.EXT4/DEV/SDB5

650) this.width=650; "src=" Http://s2.51cto.com/wyfs02/M01/8A/13/wKioL1gl39_SfdHKAABbxruKvJA219.png "title=" Extended partition 6.png "alt=" Wkiol1gl39_sfdhkaabbxrukvja219.png "/>

7. Mount, I mount to the/data directory and see the red box mounted successfully.

#mkdir/data

#mount/dev/sdb5/data

#mount

8. Permanent mount, the above mount after restarting the computer will not be, need to mount each time, here set the system boot automatically mount.

# Vi/etc/fstab

Write the following:

/dev/sdb5/data EXT4 Defaults 0 0

650) this.width=650; "src=" Http://s1.51cto.com/wyfs02/M02/8A/13/wKioL1gl4l7h2kkKAAA3ov058Ck861.png "title=" Extended partition 9.png "alt=" Wkiol1gl4l7h2kkkaaa3ov058ck861.png "/>

9. Review the results.

# df-h

All right, mount the disk and you're done.
