All of the volumes will be SSD from now on, large or small (technically, gp2 type as defined here http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/EBSVolumeTypes.html) but no, it's not currently possibly to specify the type via user data. Regardless, to specify the *volume_type* the volume needs to exist a priori and so if it an SSD type was created, that's what it's going to be.

Great! Especially also witht he IO performance. Is it possible to define the volume type manually by putting 'volume_type' to the user data? So I can also have smaller volumes with SSD? Best, Alexander

I just fixed this here https://github.com/galaxyproject/cloudman/commit/0f6ab132958ad57a338c6638711...

This required switching to SSD-based volumes on AWS and, besides actually being able to create volumes up to 16TB now, it should give us better IO performance now.

Hi,

I get this error on cluster creation:

Error creating volume: EC2ResponseError: 400 Bad Request InvalidParameterValueVolume of 2048GiB is too large for volume type standard; maximum is 1024GiB

Is there a way to get a volume that big for galaxy?

Best, Alexander
