The balancer is running even though it's disabled:
mongos> sh.getBalancerState() false mongos> sh.isBalancerRunning() true
In config.locks there is a balancer entry:
mongos> db.locks.find({_id:"balancer"})
{ "_id" : "balancer", "state" : 2, "ts" : ObjectId("59b93d04d035a79b193cea5b"), "who" : "ConfigServer:Balancer", "process" : "ConfigServer", "when" : ISODate("2017-09-13T14:13:37.034Z"), "why" : "CSRS Balancer" }
We restarted all routers (mongos) and configservers but the balancer is still running.
Btw. the dbs is not yet in use and therefore nearly empty since it's not yet in production.
