QUESTION: I am adding a new server in order to gain room for new writes as my cluster is almost filled with existing data, and perhaps even under-replicated. I don't want my new server and disks to be immediately overwhelmed by replicas for existing streams as I need room to write new streams.
...
We also suggest changing the hpRelocationVolumeFillRate to 1. This parameter is the percentage of available space on new volumes that may be filled for stream relocation during one cluster HP cycle.
To set these easily, you can use the snmp-castor-tool.sh swarmctl from the support tools bundle like this:
swarmctl
...
-C
...
bidding.relocationThreshold
...
-V
...
95
...
-d

[Swarm
