The thread I'm referring to can be found here: http://marc.info/?t=133122326800004&r=1&w=2 Subject of the thread is: "invalid bitmap file superblock: bad magic". Neil indicated that the fix in included in the following commit: http://neil.brown.name/git?p=mdadm;a=commitdiff;h=6ef89052d85b8137b8a7100f761d896ae6f61001 Bryan -- 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
