file system busy ... how?

[Marc G. Fournier]

Trying to umount a file system, and I get:

umount /vm
umount: unmount of /vm failed: Device busy


using lsof, I find nothing open on the file system:

pluto# lsof | grep vm
lsof       6548    root  txt   VREG  13,131077      19308  157977 /usr/lib/libkvm.so.2
upclient  39379    root  txt   VREG  13,131077      19308  157977 /usr/lib/libkvm.so.2

I'm the only one logged into the machine, and I'm in on / ...

and process wise, the machine is silent:

So why won't it let me umount the drive? :(

Thanks ...
