What the nodetool repair operation is

Periodically, the StorageGRID system runs the nodetool repair operation on Storage Nodes checking for and repairing metadata replication inconsistencies that may occur over time.

Nodetool repair is run every 12 to 14 days at random times on different Storage Nodes, so that it does not run on every Storage Node at the same time. The nodetool repair operation is a seamless activity that occurs in the background of normal system operations.
