hi. i've installed knoppix on my hd. after i've copied /usr to hda7 and i've joined the necessary line in fstab. the system work fine, but when i shutdown, umountfs fail to umount /usr, because it is busy (there are two error lines, one is "device is busy", the second is "/dev/hda7 not mounted ). i've tryed to join an "fuser -km /usr" to umountfs, but nothing happens .
can you help me?

thanks

alek
