A controller fault recovery system recovers from faults that cause unscheduled stops for a distributed file system operating on an array storage system having multiple controllers (312, 314, 316, 318, 320). A proxy arrangement protects data integrity in the event of an unscheduled stop on just one controller in the array storage system. An atomic data/parity update arrangement protects data integrity in the event of an unscheduled stop of more than one controller. |
