This is a long shot, but it's bitten me before.. If you log in, and then su as root while your cwd is on the raid array, that bash shell will keep the raid array busy. It backgrounds and hangs around while your su'd. Also, mount has an option to remount read-only for cases where you can't unmount. Not really sure where you could go from there, though. - 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
