It is good I can start the raid manually but it isn't supposed to work like that. Any idea why assembling from a config file would fail? Here is the latest version of the config file line (made with mdadm --examine --scan):
Jeff, You might need to update the raid superblocks during the manual assemble. mdadm --assemble --update=summaries /dev/md3 /dev/sd[c-v]1 Also, you can simplify the below a bit to the following:
ARRAY /dev/md3 level=raid10 num-devices=20 metadata=0.90 spares=4 UUID=e17a29e8:ec6bce5c:f13d343c:cfba4dc4
ARRAY /dev/md3 UUID=e17a29e8:ec6bce5c:f13d343c:cfba4dc4

However you should be able to assemble the array by simply listing all the non-spare devices: mdadm -A /dev/md3 /dev/sd[c-v]1 NeilBrown -- ------------------------------ Jeff Johnson Manager Aeon Computing jeff.johnson "at" aeoncomputing.com <mailto:jeff.johnson@xxxxxxxxxxxxxxxxx> www.aeoncomputing.com <http://www.aeoncomputing.com/> t:858-412-3810 x101 <tel:858-412-3810%20x101> f:858-412-3845 <tel:858-412-3845> 4905 Morena Boulevard, Suite 1313 - San Diego, CA 92117 -- 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
