First, mdadm didn't like running an array as a seperate step to assembling it. (mdadm -R /dev/md0 was giving me "Invalid Argument"). Doing this in one step however did work. Secondly, I suspect the two devices weren't synced even though mdadm -E wasn't showing this which was casuing attempts to assemble an array containing both devices to quietly fail. The final sequence which worked was: reboot mdadm --assemble /dev/md0 --run /dev/hda2 mdadm /dev/md0 -a /dev/hde2 Easy when you know :-) Ali. --=20 http://www.fastmail.fm - Same, same, but different=85 - To unsubscribe from this list: send the line "unsubscribe linux-raid" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
