Here We are going to see how to add volumes on the instance using Elastic Block Storage(EBS)
- Create a EC2 Instance with Ubuntu OS and with instance type as t2.nano and selected the existing key pair and security group to launch the instance.
- Go to Elastic Block store select volumes
- Create a Volume and set 10 GB as additional storage
- Once volume is created attach the volume on the instance which we created
- login to the instance via ssh and view the attached volume using list block "lsblk"and formate the file system type to "ext4"

- To mount the formatted volume we need to create a directory we can mount the volume with file name or UUID
ubuntu@ip-172-31-47-222:~$ sudo mkdir /data
ubuntu@ip-172-31-47-222:~$ sudo file -s /dev/xvdf
/dev/xvdf: Linux rev 1.0 ext4 filesystem data, UUID=adc5036f-9501-4b72-951e-1cf30aa4bf72 (extents) (64bit) (large files) (huge files)
ubuntu@ip-172-31-47-222:~$ sudo mount UUID=adc5036f-9501-4b72-951e-1cf30aa4bf72 /data
ubuntu@ip-172-31-47-222:~$ df -Th

/dev/xvdf ext4 9.8G 24K 9.3G 1% /data
- If we reboot the instance the attached volume will not detected to keep detect after reboot or restart the instance we need to backup the volume file.
ubuntu@ip-172-31-47-222:~$ sudo cp /etc/fstab /etc/fstab.backup
ubuntu@ip-172-31-47-222:~$ sudo vi /etc/fstab
- make an volume file entry on the "sudo vim /etc/fstab"
on the above path we can use either path or UUID of the volume.
Mount the Volume file
ubuntu@ip-172-31-47-222:~$ sudo mount -a
ubuntu@ip-172-31-47-222:~$ df -Th
Filesystem Type Size Used Avail Use% Mounted on

Now the Volume file were mounted permanently.
