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?

beast log # cat /proc/mdstat
Personalities : [raid0] [raid1]
md1 : active raid1 sda1[0] sdb1[1]
88256 blocks [2/2] [UU]

md3 : active raid1 sdb3[1] sda3[0]
193310080 blocks [2/2] [UU]

unused devices: <none>

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?

but I dont have NFS sharing running on it..
