Abstract
Managing a redundant array of independent disks (RAID) storage array involves assigning first and second stripes to span respective first and second sets of disks. A subset of drives in the first set fails such that the first stripe is in a first state wherein a failure of another drive in the first set will lead to data loss in the first stripe. It is determined that the second stripe is in a fault-tolerant state such that the second stripe can have failures of two drives in the second set before the second stripe is in the first state, Part of an operational disk of the second set used by the second stripe is allocated to the first stripe to replace at least part of the subset of failed drives.
