Add disk on VM Virtualbox

Scenario:

• We have to add disk in our linux OS machine, So we have added 10 GB in VM disk.

Output:

Create disk on vm with extension .vdi

screenshot Image below:

• Check entry on disk by typing command fdisk -l, we have already added 10GB so we will make raw partiton on disk /dev/sde.

• Create new Partition on /dev/sde

          srv2:~ # fdisk /dev/sde

Welcome to fdisk (util-linux 2.33.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.


Device does not contain a recognized partition table.
Created a new DOS disklabel with disk identifier 0xe090b3b3.


Command (m for help): n
Partition type
   p   primary (0 primary, 0 extended, 4 free)
   e   extended (container for logical partitions)
Select (default p): p
Partition number (1-4, default 1): 1
First sector (2048-20971519, default 2048):
Last sector, +/-sectors or +/-size{K,M,G,T,P} (2048-20971519, default 20971519):


Created a new partition 1 of type 'Linux' and of size 10 GiB.


Command (m for help): w
The partition table has been altered.
