The capacity balancing service ensures that the percent of HCP storage space used on the storage nodes in the system remains roughly equivalent across the nodes when new nodes are added.
When the capacity balancing service runs, it evaluates the storage level for each node without regard to the individual logical volumes the node manages (the amounts of available storage may vary greatly among those volumes). If the storage levels for the nodes differ by a wide margin, the service moves objects around to bring the levels closer to a balanced state.
The capacity balancing service runs only when started manually. Typically, an authorized HCP service provider starts this service after adding new storage nodes to the system.

Note: The capacity balancing service does not balance the storage space across nodes for data stored through namespaces that have economy storage devices set as their ingest tier. For information on ingest tiers, see Choose the ingest tier. |
