This ticket will only involve making sure donors/recipients/coordinators have removed all disk metadata after having completed the resharding operation.

This should include:

• Removing the reshardingFields parameter from the original config.collections entry on the coordinator after the coordinator has transitioned to kDone.
• Removing the config.reshardingOperations document for the current resharding operation after the coordinator has transitioned to kDone.
• Removing the config.localReshardingOperations documents on for the current resharding operation on recipients/donors after the recipients/donors have transitioned to kDone.

Note that for this ticket and Milestone 2 in general, you don't need to worry about handling any error state cleanup.
