Adding a new Disk - Ubuntu

After adding a New Disk from the Storage menu to your Virtual Machine, you will need to partition, format and mount the disk before you can use it.

Step 1 - check if the disk is recognized and find the disk name:

lsblk -o NAME,SIZE,FSTYPE,MOUNTPOINT

The command will return something similar, where vda is the name of our new disk:

If FSTYPE is empty it means the disk is not formatted yet. (Command for this in step 3)

Step 2 - partition the disk using fdisk:

sudo fdisk /dev/vda

• Press n (New partition)

• Choose Primary and Partition Number (default 1)

• Press Enter to accept the full disk size.

• Press w to write changes.

Step 3 - format as ext4 type:

sudo mkfs.ext4 /dev/vda1

Step 4  - mount the disk and make it persistent:

# make a new dir mounting point
sudo mkdir /mnt/newdisk

# mount the disk to the previuosly receated mount point
sudo mount /dev/vda1 /mnt/newdisk

# verify the new mount point
df -h | grep /mnt/newdisk

Step 5 - make it persistent on reboots:

echo "/dev/vda1 /mnt/newdisk ext4 defaults 0 0" | sudo tee -a /etc/fstab
