Abstract:
1. A method for analyzing a Level 5 RAID array when a volume of the Level 5 RAID array is identified as degraded to determine whether at least some portion of the Level 5 RAID array should be rebuilt, comprising the steps of reading a section of data in the Level 5 RAID array, the section of data having a size that is a multiple of the stripe size of the data of the Level 5 RAID array; determining whether the data in the section of data has been compromised; rebuilding the data in the section of data of the degraded volume only if it is determined that the data in the section of data has been compromised, wherein the data in the section of data of the degraded volume is not rebuilt if it is determined that the data in the section of data has not been compromised; and for each additional section of data in the Level 5 RAID array, performing the steps of reading, determining, and rebuilding until all stripes of the Level 5 RAID array have been read for the purpose of determining whether the data in the sections of the Level 5 RAID array has been compromised.
