AWS launches new EBS feature called Elastic Volumes which allows you to increase volume size, adjust performance or change the volume type while the volume is in use. The feature is available for all current-generation EBS volumes attached to current-generation EC2 instances.
Use cases :
- Change the volume type on the go.
- Increase provisioned IOPS of volume to handle the spike in traffic, and then dial it down afterward.
- Increase the size of the volume and expand the file system to match, with no downtime.
You can manage all of this from the AWS Management Console, via API calls, or from the AWS Command Line Interface (CLI).
The next step is to expand the file system so that it can take advantage of additional storage space. Here are the steps of Expanding the Storage Space of an EBS Volume on Linux or Expanding the Storage Space of an EBS Volume on Windows.
