After you’ve installed brand new disks on your server, you have to use

tools like fdisk to partition it accordingly.

 

Following are the 5 typical actions (commands) that you can execute

inside fdisk.

 

• n – New Partition creation

• d – Delete an existing partition

• p – Print Partition Table

• w – Write the changes to the partition table. i.e save.

• q – Quit the fdisk utility

 

Create a partition

In the following example, I created a /dev/sda1 primary partition.

# fdisk /dev/sda

Command (m for help): p

 

 

Disk /dev/sda: 287.0 GB, 287005343744 bytes

255 heads, 63 sectors/track, 34893 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System

 

 

Command (m for help):  n
