I want to unmount /hypercd without rebooting system. Using "umount", it says "umount: 0506-349 Cannot unmount /dev/cd1: The requested resource is busy".

I've tried umount ("/hypercd" and "/dev/cd1" and "/dev/cd1 /hypercd" as well as using the "-f" flag with those derivations but get the same error message.

I've also tried "fuser /hypercd" (alone and with the "-k" and "-u" flags), as well as "fuser /dev/cd1" to no avail. The "fuser" command never returns anything except "/hypercd:".

The user already tried to reboot and that didn't work, but that is most likely because of entries in /etc/filesystems (which had "mount=true"). I thought that part of my issue might have been because /hyperlib had a soft link from bin to /hypercd/bin, thinking that is what might be hanging me up, I removed it and tried the above items again (obviously still a no go).

So, now I have tried what I know, searched here in the forums and commented out the appropriate entries in /etc/filesystems, my only other option that I know of is to reboot the system so that the modified /etc/filesystems will yield the result I want. I would rather not reboot.

Does anyone have any other ideas?

TIA
