One step at a time. Show your automount tables: are you using direct
automounting, which requires "/sbin/service autofs reload" ? Or
indirect automounting, which should just work? And when you say you
"unmounted directories on client side", how exactly did you do that?
Did you do "umount /mount/dir" and get a successful unmount? Or did
you do a naughty thing and use "umount -l", which can create chaos
without careful handling?

If you have old software holding open the mount point, the
automounting changes *will not* overwrite the old mountpoint until
they are released properly. And it shouldn't!
