For anyone who really cares (probably no one), the system has now transferred more than half the data over from the backup to the RAID system. I have not yet experienced a single halt. Performance seems good (I'll test a lot more once the data has transferred and I can take the backup array offline). With the RAID array more than 40% full, creating a file takes almost no time. Deleting a 23G file takes less than 0.9 seconds. -- 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
