• For automatic relocations, the system uses up a maximum of one disk worth of chunklets per system node. • When selecting a target chunklet for relocation, the system attempts to identify a local spare chunklet, a local free chunklet, a remote spare chunklet, and then finally a remote free chunklet. NOTE: Local chunklets are chunklets on disks whose primary path is connected to a node that owns the logical disk containing the chunklets being relocated. • If the system uses up its free or spare chunklets for relocation, an alert is generated. • Once the spare and free chunklets are used up, automatic relocation no longer occurs. In most cases, some data redundancy is lost. The system also generates an alert. Spare Chunklets 33

Local chunklets are chunklets on disks whose primary path is connected to a node that
