Subject Re: no other nodes seen on priam cluster
Date Thu, 28 Feb 2013 06:31:15 GMT
Off the top of my head I would check to make sure the Autoscaling Group you
created is restricted to a single Availability Zone, also Priam sets the
number of EC2 instances it expects based on the maximum instance count you
set on your scaling group (it did this last time i checked a few months
ago, it's behaviour may have changed).

So I would make your desired, min and max instances for your scaling group
are all the same, make sure your ASG is restricted to a
single availability zone (e.g. us-east-1b) and then (if you are able to and
there is no data in your cluster) delete all the SimpleDB entries Priam has
created and then also possibly clear out the cassandra data directory.

Other than that I see you've raised it as an issue on the Priam project
page , so see what they say ;)

Cheers

Ben
