How to restart cluster services without being affected

Configuration before horizontal expansion: heartbeat { mode mesh address 192.168.127.128 port 3002

all cluster

mesh-seed-address-port 192.168.127.128 3002 mesh-seed-address-port 192.168.127.131 3002

# aerospike_mesh.conf for alternative.
interval 150
timeout 10      
}

That is not exactly a Go client question - but by adding an additional node and letting it know about the existing nodes, it will automatically join the cluster and start data migrations. Once partitions (shards) are moved to the new node, the clients would automatically start using it without any change in the application side.

For more information about that process: https://aerospike.com/docs/operations/manage/cluster_mng/adding_node/index.html
