Currently have three-node cluster in a single data center; all nodes are both master/data eligible. I'm trying to migrate to six-node cluster across three separate DCs for increased reliably with this topology:
DC1: 1. Master-only 2. Data-only DC2: 1. Master-only 2. Data-only DC3: 1. Master-only 2. Data-only Any suggestions for how to upgrade my existing boxes to this to minimize downtime? Can I reuse existing boxes? What happens when a data-node gets transformed into master-only? Will it offload its existing indicies? Or should I just do full cluster backup, startup new boxes, and restore? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
