This question comes up a lot, especially from people who's computers
don't poweroff immediatly after that message gets posted. You see, /
can't be unmounted since the shutdown script is running off it, so it
gets mounted ro. The act of mounting ro syncs the disks. Then since
the filesystem is still mounted, the raid array can't be shut down.
However, there is no data activity at this point and the filesystem is
consistant.
In other words, don't worry about it. I haven't heard of anybody having
difficulty. Since its a generic error message (the raid system doesn't
know the system is shuting down), its too bad that the sysvinit
maintainers don't put a message in the shutdown script to "Ignore the
following warning about not being able to shutdown the raid partition".
