I appreciate the help that everyone here has been providing with this frustrating problem. It looks like there's agreement that I need to use "--force" to assemble the array with the disk devices specified. Here's my first cut at a command to try: mdadm --force --assemble /dev/md0 /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1 /dev/sde1 /dev/sdf1 /dev/sdg1 /dev/sdh1 /dev/sdi1 /dev/sdj1 /dev/sdk1 /dev/sdl1 /dev/sdm1 /dev/sdn1 /dev/sdo1 http://lairds.us/temp/ucmeng_md/suggested_recovery I'm sure I'm missing something. Corrections are welcome. (It would be comforting if mdadm had a "--dry-run" option.) Thank you, all! --kyler -- 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
