Once I have created an EBS of IOPS type and attached to an EC2 volume, is there a way to change its settings such as storage and IOPS? I am fine detaching it and making changes. Obviously I want to retain data.
I am looking for an answer preferably on the AWS Console but even a command line approach is welcome.
I am using Windows AMI.
Yes, You can modify your EBS Volume without any downtime.
AWS recently announced Elastic Volumes, which make it possible to modify the volume type (SSD/HDD/PIOPS), volume size (GB), and provisioned IOPS of EBS volumes with no downtime or performance impact.
All EBS volumes have been converted into Elastic Volumes as of today, so this functionality is already available in your AWS account!
Simply right click the EBS volume -> Modify and enter a new IOPS value.
