Abstract
A storage system with redundant mass storage device arrays determines that a mass storage device is non-responsive, and individually offlines the specific mass storage device for a temporary period. Reads to the offline mass storage device may be temporarily prevented from reaching the mass storage device, and may be serviced by a redundant array. Write to the offline mass storage device may also be temporarily prevented from reaching the mass storage device, and may be serviced with a temporary storage management that tracks and/or stores write transactions. The mass storage device can be synchronized with the write transactions on the basis of the tracking.
