I just expanded our RAID5 software raid from 6 to 9 disks. Prior to the change, there were no problems. There were no errors on the console or in the logs after installing the disks, before reconfiguring the RAID. I had some data corruption problems with "raidreconf" so I reconstructed the RAID from scratch. Again, no apparent errors. When I began to restore the data to the array, /dev/sdc generated some errors (see below) and was marked faulty, then kicked from the array. The hot spare was picked up and synced properly. I have now completely restored the data but I want to fix whatever was wrong with "sdc" and add it back into the array. I could find no documentation about how to remove the "faulty" flag or check the disk for bad blocks without adding it to the array. I'm assuming that it may have had some bad spots on the disk, but it's a little suspicious that this happened after upgrading the array. This particular disk drive was not physically touched during the hardware upgrade. All other drives appear to be operating normally. I'd appreciate any feedback you folks can offer. --Cal Webster Network Manager NAWCTSD ISEO CPNC cwebster@ec.rr.com - 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
