MongoDB Error 163: Zone Still In Use
Description
This error indicates that you are attempting to drop a zone in a MongoDB sharded cluster that is still in active use. MongoDB prevents dropping zones that are currently associated with shards or ranges, or if the zone is still referenced by a sharding configuration, to maintain data consistency and cluster stability.
Error Message
Zone Still In Use
Known Causes
3 known causesZone Associated with Shard(s)
The zone you are trying to drop is currently assigned to one or more shards in the cluster, making it an active part of the sharding configuration.
Active Data Ranges
The zone is still being used to define data ranges for sharded collections, meaning data is currently directed or restricted by this zone.
Metadata Reference Exists
Even if not actively routing data, the zone might still have lingering references within the cluster's sharding metadata, preventing its removal.
