I don't know. But you could also use raid10, which is another driver, and thus it may not have the problem. raid10,n2 is equivalent in almost all aspects to raid1 raid10,f2 can be used as a replacement for raid1 (and raid10,n2) and has about double the speed for sequential read, while the other common operations are about the same. best regards keld -- 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
