i have a 4 disk array which (due to power problems) has bad sectors on two of the disks. as far as i can tell the bad sectors are not in overlapping stripes of the raid -- so in theory every stripe has 3 components still available. but the kernel doesn't like this situation because it considers a disk to be either all good or all bad :) is there an offline tool which can reconstruct such an array? or even an offline tool which already has the parity calculation code and such which i could extend to support such reconstruction? i considered copying the two bad disks with "dd conv=noerror,sync", which would stop the kernel from marking the drives as bad, but that seems a bit less than ideal because i really would like to reconstruct the bad stripes using the 3 valid copies and not include an all-zeroes copy created by dd. -dean - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
