This is telling you that /dev/hde - or one of it's partitions - is "Busy". This means more than just 'open'. It means mounted or included in an md or dm array, or used for swap. You need to find out what is keeping it busy. Most likely dm or md. What does cat /proc/mdstat show? I don't know much about dm - is there some 'pvlist' command or similar that will show all the phys volumes it is holding on to.. Or possibly just look in /sys/block/hde/holders NeilBrown - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
