Formating & mounting a disk on Linux

• On your Linux VM, to do this we need to be the root user and run the following command: fdisk -l, as we can see the new hard drive, 10GB, is assigned to the path /dev/vdb.

• After the new hard disk has been identified, the next step is partitioning, for this, we will use the following syntax:

fdisk /dev/vdb

Common fdisk parameter are:

• n: Create a new partition.

• P: Print the partition table.

• d: Remove a partition.

• q: It leaves without saving the change.

• w: Save the changes and exit the command. With this in mind we will perform the following process once the fdisk /dev/vdb command has been executed: Enter the letter n to create the new partition. - Enter the letter p to define as a primary partition - Number 1 to establish a single partition of the new disk. - Establish the value of the first sector which is 2048 by default. - Establish the value of the last sector which is 20971519. - Save the changes using the letter w.

• We can see that the process is executed correctly. If we run fdisk -l we can look at the changes in the new disk (/dev/vdb).

• Next step is to format the new hard drive with the desired file system using the command

mkfs.ext4 /dev/vdb1

mkfs is make file system

• After that we need to create a new directory, in this tutorial we create a new directory called /data:

mkdir /data

• The Next step is to mount the new disk in the desired location, in this tutorial we have created a new directory called /data. use command

mount /dev/vdb1/ /data

• If we want that partition to be mounted permanently, it will be necessary to edit the file /etc/fstab using the preferred editor and to enter the following line. We keep the change.

/dev/vdb1 /data ext4 default 0 0

• After that, use df -h command to see mounted hard drive.
