My impression was that a bitmap only helped on an unclean shutdown or on re-adding a disk that was previously removed, and not on failing a drive and adding a new one. Is that accurate? (Of course it would help the OP if he has another unclean shutdown.) As Neil posted last month, you can't use mdadm 3.2.3 to create the bitmap; use 3.2.2 or check out from git. (I just ran into the bug in 3.2.3 and found the message in the archive.) --keith -- kkeller@xxxxxxxxxxxxxxxxxxxxxxxxxx -- 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
