Abstract
A method of automatic load rebalancing includes determining that a new storage device was added to a storage array comprising a plurality of storage devices, wherein the new storage device is distinct from the plurality of storage devices. The method further includes, in response to the determining, identifying a first shard on a first storage device of the plurality of storage devices, wherein the first storage device has a fullness metric that is equal to or exceeds a fullness threshold. The method further includes moving, by a processing device of a storage array controller of the storage array, the first shard from the first storage device to the new storage device.
