| Description |
|
During the test of resharding during defragmentation, the chunks are moved back to shard 0 after resharding finishes. Now that defragmentation disables balancing on the collection it is running on, this is not necessary and can potentially cause failures due to both migrations trying to happen simultaneously. |
