Absolutely 100% for certain? If there is any chance of a problem I can --stop the array before removing the drive. The volume is used for a Bacula network backup that is often idle. The third drive will never be on site (think about the risk), but that just means that the array will grow from 2->1 and then from 1->2 instead of from 2->3 and 3->2. -- 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
