How to Attach AWS EBS Volume to AWS EC2 Instances

Step 1: Select correct EC2 instance

Make sure you have selected the correct EC2 instances to which we are going to add additional or new aws EBS volume.

Step 2: Identify AWS Availability Zone

Go to storage section, find how many EBS volumes have been attached to aws EC2.

So primarily you’ll be having a root EBS volume and also identify the availability zone of EC2 instance where it is running.

We can attach multiple aws EBS volumes to a single instances but the volumes we create and the instance must be in the same availability zone.

Step 3: Create new AWS EBS Volume

Go to volumes and Click on Create volume.

Specify new AWS EBS Volume details like Volume type, size, IOPS, Throughput, Availability Zone and other info as you prefered. Dont forget to select the right availability zone of our EC2 is running.

Once you entered all details, just click on create volume.

Go to volumes again to verify the state of newly created AWS EBS Volume. it should be in ‘available’ state for now.

Step 4: Attach new AWS EBS Volume

Go to actions, Click on Attach volume.

Note: Volume Status will be changed from “Available” to “In Use”.

Step 5: Create filesystem & mount AWS EBS Volume on AWS EC2

Login into EC2 instance and find the new device id that is created by OS kernel using “fdisk -l” or “lsblk” commands.

In order to mount this volume we have to create a file system. Lets create a xfs file system type on this EBS volume.

sudo mkfs.xfs /dev/xvdf

Mount volume on a target directory using mount command.

sudo mount /dev/xvdf /mnt
