Abstract
Systems and methods for recovering from a fault in an array of data storage devices are provided. Fault recovery includes determining that a first data storage device of the array of data storage devices is more likely to fail that other storage devices of the array of data storage devices. A second data storage device in the array of data storage devices is selected to be used in recovering from a failure of the first data storage device. Data from the first data storage device is stored at the second storage device. In the event of a failure at the first data storage device, data storage operations are performed using the second storage device.
