      Starting in 3.6, when a shard mongod loads the chunk metadata for a sharded collection, it records that metadata durably. If the mongod restarts, however, the in-memory cache of that information is lost and isn't loaded until a metadata refresh is triggered via a request from a mongos. Shard mongods should load the routing information from its persistent local copy into memory at startup.
