I can see from https://docs.memsql.com/v7.0/guides/cluster-management/operations/taking-leaves-offline-without-cluster-downtime/ that it is easy to do leaf maintenance with HA-2.
Is it possible to do a similar process with HA-1? I mean, if I want to reduce the size of the cluster (lets say that I dont need that many memory anymore), what is the correct process? To me it is not clear if DETACH LEAF should be used on that case, as Im not sure it will force the data from that LEAF to be rebalanced in the remaining nodes.
I’ll need to upgrade the disks on a cluster with HA-1 scenario soon. That is why Im asking.
