Amazon Elastic Block Store (Amazon EBS) is an easy-to-use, scalable, high-performance block-storage service designed for Amazon Elastic Compute Cloud (Amazon EC2).

Note:- My EBS block name is xvdf, so be carefull when writing block name

• To attached EBS, it should be in same Availability zone.
• Now create an EBS and provide the size.
• Now open EBS dashboard and attach it to the same availability zone instance.
• Now SSH that instance and type lsblk and hit Enter, Now you can see all the storage of that instance.
• But you can't access it now, to access it we have to format that EBS storage.
• To format it, type this in your root directory sudo mkfs.ext4 /dev/xvdf
• Now that EBS is formatted and ready to use, but not mounted.
• To mount it Go to root directory using cd/ , now type mkdir /new_volume/
• Now type mount /dev/xvdf /new_volume/ hit enter, and you are DONE!!
• To check type mountpoint /new_volume

To de-attach that EBS from EC2

• Go outside from that EBS directory and type umount /new_volume/
• Now detach this EBS from AWS EBS Dashboard. Done!!
