If a Storage Node has not been able to communicate with other Storage Nodes for more than 15 days, the Storage Node cannot rejoin the grid. The consistency control affects how the metadata that StorageGRID uses to track objects is distributed between nodes, and therefore the availability of objects for client requests.
