A 'cat /proc/mdstat' will show which partitions are active in each md set. Use 'mdadm --add /dev/md_device /dev/partition_device' to add back the missing partitions, being careful to match up the right device names for the raid sets and partitions. This will start a sync with the newly added and you can watch the progress with 'cat /proc/mdstat'. I'm not sure exactly what conditions trigger an automatic sync and what requires the manual one but if the system goes down cleanly they will pair up at reboot as long as the partition type is FD. -- Les Mikesell lesmikes...@gmail.com _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
