root@hostname /# umount /tmp
umount: error unmounting /dev/hd3: Device busy
root@hostname /# df -k /tmp
Filesystem    1024-blocks      Free %Used    Iused %Iused Mounted on

Hi, If your corrupted filesystem is /tmp you shouldn't be able to umount it.  The fsck should be run in maintenance mode.  Shutdown the machine and boot it in maintenance mode before mounting filesystems. In that mode run the fsck.
