Oops, only 5 drives, but I know data is OK on all 6 drives. I also know that there are bad blocks on more than 1 drive. So I want MD to recover from the other drives in those cases, which I won't be able to with only 5 drives. In other words, checking/repairing with only 5 drives will lead to data corruption. I'll stop and try again, listing all 6 drives by hand: # mdadm --stop /dev/md1 # mdadm --assemble /dev/md1 --force /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1 /dev/sde1 /dev/sdf1 mdadm: /dev/md1 has been started with 5 drives (out of 6). Ugh. Didn't work. Bug? How do I force MD to raise the event counter on sdb1 and accept it into the array as-is, so I can avoid bad-block induced data corruption? - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
