I just merged the new code that supports EBS-backed clusters and also
the new cluster compute types on github. Thanks to Fred Rotbart for his
contributions to the cluster compute support.
The github code now supports starting/stopping EBS clusters. The stop
command will stop any EBS-backed instances rather than terminating them.
Normal instance-store instances will be terminated by the stop command
as they've been in the past.
There's a new command called 'terminate' that will destroy an EBS
cluster given that the stop command will only 'stop' an EBS-cluster. The
'stop' and 'terminate' commands are identical in behavior in the case of
normal instance-store (S3) instances.
Right now Fred is sharing his AMI publicly for the new cluster compute
instance types. I need to migrate Fred's image to the StarCluster
account so that it will be available via "starcluster listpublic" but
for now you should be able to use his image (ami-30b84d59) with the
github code without issues. I used his image to test the new code.
I'm hoping to publish a release candidate for testing soon before
releasing the official 0.92 version. Please let me know if you test the
github code and have any issues.
