I've got a usb HD mounted, and it has been mounted since the weekend,

now I"m done with it an want to umount it, but neither umount nor the on-screen icon (when right-clicked) will let me do it:
it is /dev/sdd1, mounted as /media/seagateusb. when root tries to umount it we get this:
<snip> It's under control of autofs. You can open the GUI file manager, and do a safely remove/eject.
Or you can stop autofs for a minute, and then umount it.
actually, no I can't. if I right-click on seagateusb and click unmount, I get an error box saying "Unable to unmount seagateusb. Cannot unmount because file system on device is busy."
<snip> Ok, try lsof /media/seagateusb - that may tell you what's holding it.
Did you try service autofs stop?
yes, made no difference.
another responder suggests it is journalling block device daemon/ thread/whatever holding the device. looking into that as we speak
Got tired of fooling with it and did a "umount -l" which immediately released the drive. probably left some jbd2 thread hanging loose, but at this point I"m not too concerned.
thanks for the suggestions!
