Hi Sonia:
Thanks, yes I understand the workaround (my Magnetic AMIs still work fine) … just wanted to use the SSDs, as they're part of 'normal' EC2 these days. I didn't see the other issue (had searched for SSD instead of gp2) … thanks!

Subject: Re: [StarCluster] InvalidParameterCombination error with General Purpose SSD AMIs
Hi,
I'm new to StarCluster but I ran into this bug before.
The AMIs in question in my case were my customized AMIs that I modified (adding tools and such) from the public StarCluster AMI. What I found is that although the customized AMIs was based on fully-StarCluster-functional AMI with volume type=Magnetic, the instance I used to modify AMIs used gp2 SSD. My workaround was 1) start an instance with the customized StarCluster-not-functional AMI and specify volume type=Magnetic for that instance. 2) create an AMI from the instance. The resulting AMI became fully-StarCluster-functional again (at least in my case).
Hope this is helpful and hope that in the near future StarCluster will support gp2 volumes as others have requested here

Cheers,
Sonia

Hi StarCluster Community:
I just submitted an 'issue' (
https://github.com/jtriley/StarCluster/issues/448), but I thought I would mention this here as well, in case someone has any thoughts.
When using an AMI with volume type = General Purpose (SSD), I get (in debug.log):

The AMIs in question are clones of fully-StarCluster-functional volume type = Magnetic.
