While you are practicing Oracle on virtual box, you might need additional hard disk space.
This can be achieved by adding a hard disk to virtual box machine under settings and mounting it on a specific directory.
Add hard disk virtualbox
Shutdown the VM, go to settings, select storage and add new HDD. Give the HDD size as to how much space you want to add.
Format new hard disk
Start the VM, and now it’s time to format the newly added hard disk
# fdisk -l -- select the name of the newly added hard disk. look at the size # fdisk /dev/xvdb -- create a primary partition. enter (p) -- hit enter -- hit enter -- hit enter -- type w to save newly created partition
Create directory and mount disk
Once you have created a full partition of the hard disk, create a directory where you will mount this disk
List the exact name of the partition suing below command
# fdisk -l /dev/xvdb
Generally the partition will always be <disk_name> + 01 for first partition. Example, in our case, the partition name is /dev/xvdb01.
Mount the partition on /u03
# mount /dev/xvdb01 /u03
Verify the mount is done
df -h lsblk mount -a ldblk
Add to /etc/fstab file
Find the UUID of the hard disk
ls -lrt /dev/disk/by-uuid
Copy the UUID from above output for /dev/xvdb disk and add below entry to /etc/fstab file. Make sure to change the UUID as per your server details
vi /etc/fstab UUID=2a20cd87-f89e-4c59-945f-3700d8d1e08f /u03 ext4 defaults 0 0
