Re: 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
https://github.com/jtriley/StarCluster/issues/264

Cheers,
Sonia
