Out of memory, ejection not taking place, cluster useless

Couchbase Server

Thank you for the reply.

  1. Excellent point. I missed or didn’t realise that I don’t need the indexing service when I need the documents to be indexed only by ID. The comunity edition does not allow me to turn the indexing service off though and the minimum RAM quota is 256 MB, but it helps anyway.

  2. Well, the sizing guide tells me that I need over 60 GB just for the metadata :slight_smile: Not very useful for my usecase. I can’t use too many resources for this cluster, so I’ll have to keep 4 GB per node.

  3. I was using the Couchbase way of counting the replicas - I ment 1 master + 2 replicas. I was seriously considering using only one replica when I was designing the cluster because it runs on VMs, so I don’t have to worry about hardware failures, but I chose more safety in the end.

I reconfigured the RAM quotas, lowered the number of replicas to 1 and run the reballance again. Hopefully I will have a healthy cluster sometime tomorrow.
