Growing Amazon EBS Volume sizes [closed]

Answer 1

My steps:

1. stop the instance
2. find the ebs volume attached to the instance and create a snapshot of it

3. create a new volume with bigger disk space using the above snapshot. Unfortunately the UI on the aws console to create a snapshot is almost unusable because it's listing all the snapshots on aws. Using command line tool is a lot easier, like this:

   ec2-create-volume -s 100 --snapshot snap-a31fage -z us-east-1c
   

4. detach the existing ebs (smaller) volume from the instance

5. attach the new (bigger) volume to the instance, and make sure attach it to the same device the instance is expecting (in my case it is /dev/sda1)
6. start the instance

You are done!

Other than step 3 above, you can do everything using the aws management console.

Also NOTE as mentioned here:

the device on your ec2 instance might be /dev/xv* while aws web console tells you it's /dev/s*.
