Shrinking an EON cluster from 12 to 6 nodes

DieterC

Dear forum,

We're currently timing the queries for xxx on a 12-node cluster, using 12 shards.

We would like to repeat the tests with 6 and/or 4 nodes, and would like to shrink the cluster not one node at a time, but removing for example 6 in one go.

We were thinking of calling admintools, Advanced Menu -> Cluster Management -> Remove Host(s), followed by terminating 6 nodes from the AWS EON management console.

What is your take on this? is there a more efficient, safer, more elegant or better for any other reason solution?

Thanks for any hints & cheers -
Dieter and Marco

Hi Dieter,
You can add and remove nodes from the cluster using the MC as well as admintools. Unfortunately, the MC currently adds and removes one node at a time (soon to be fixed) so admintools could be faster for you.
