Impact of decommissioning on system operations

Storage Node decommissioning involves the transfer of large volumes of object data over the network. Although these transfers should not affect normal system operations, they can have an impact on the total amount of network bandwidth consumed by the StorageGRID Webscale system.

Tasks associated with Storage Node decommissioning are given a lower priority than tasks associated with normal system operations. Therefore, decommissioning does not interfere with normal StorageGRID Webscale system operations, and does not need to be scheduled for a period of system inactivity. Because decommissioning is performed in the background, it is difficult to estimate how long the process will take to complete. In general, decommissioning finishes more quickly when the system is quiet, or if only one Storage Node is being decommissioned at a time.

Upon the successful decommissioning of a node, its services will be disabled and the node will be automatically shut down.
