Apparatus, system, and method for differential rebuilding of a reactivated offline RAID member disk |
摘要 |
An apparatus, system, and method are disclosed for rebuilding only changed stripes of an offline member disk in a RAID array that is configured with redundancy and no hot standby disk. A work-in-progress ("WIP") map tracks the changed stripes of the offline member disk prior to a reactivation and records the completion of the differential rebuilding ("DR") process on the stripes. The DR process shortens the duration of a degraded mode of operation entered into by a logical drive formed when the RAID array experiences a member disk failure that results in one member disk being designated as offline.
