Here is how to prepare additional disk on Linux for more storages.

Find the disk drives represented by /dev/sd*

ls /dev/sd*

Result looks like:

/dev/sda /dev/sda1 /dev/sda2 /dev/sdb

Additional hard disk is: /dev/sdb

Create a new partition on the new disk.

fdisk /dev/sdb

Command (m for help): c
DOS Compatibility flag is not set

Command (m for help): u
Changing display/entry units to sectors

Command (m for help): p
Disk /dev/sdb: 980.6 GB, 1052911232614 bytes

Command (m for help): n

Enter p: p

Partition number (1-4): 1
[Press Enter]

Now, save the configuration.

Command (m for help): w

Check the disks.

ls /dev/sd*

Creating File System:

/sbin/mkfs.ext4 -L /backup /dev/sdb1

Mount the File System.

mkdir /backup
mount /dev/sdb1 /backup

Show mounted disk.


Auto mount at startup.

Add the below entry to /etc/fstab file.

LABEL=/backup /backup   ext4  defaults   1  2

Save and exit the fstab file, and reboot your machine.

The storage is ready at /backup
