shutdown fails because mdraid fails to stop device

[dirtbag]

hey folks... Im not sure at what point,but my gentoo server will not shutdown cleanly.. basically I get something like

* Bringing down interface lo
* Removing addresses
* Unmounting loop devices
* Unmounting filesystems
* Shutting down the Logical Volume Manager
* Finished Shutting down the Logical Volume Manager
* Shutting down RAID devices (mdadm) ...
mdadm: stopped /dev/md1
mdadm: failed to stop array /dev/md3: Device or resource busy
Perhaps a running process, mounted filesystem or active volume group? [ !! ]
* ERROR: mdraid failed to stop
* Stopping udevd ... [ ok ]
* Terminating remaining processes ... [ ok ]
* Killing remaining processes ... [ ok ]
* Saving dependency cache ... [ ok ]
* Remounting remaining filesystems read-only ...
* Remounting / read only ... [ ok ]
INIT: no more processes left in this runlevel

It hangs here and I have to hit the reset button to reboot my server ..
any ideas on why?

You didn't mention where md3 is mounted originally. Is it your root or home possibly? Are you maybe making this fs a network share and not mentioning that earlier on in the shutdown, that shared network still had people hanging off of it?

yeah the md3 is my / partition
but I dont have NFS sharing running on it..

maybe samba shares? I guess i need a better log of whats going on during shutdown..
