We are having a two node cluster of aerospike. We thought of adding two more nodes to the cluster. As soon I added them we are getting queue too deep error on new nodes and as well Device over load on client.
I tried of making migrate-max-num-incoming from 256 to 4. Still the issue persists.
What is the best way to add a new node to cluster without impacting the clients.
More info: 1) We are using SSD based installation 2) we are using mesh node architecture
Also, Did you validate your new node’s SSD before adding them in production? Aerospike recommends to do one round of ACT benchmarks for 24 hours before adding any new node in production.
