Yes, it does work but how do I make it load automatically on boot?
(Obviously, I already have geom_mirror_load="YES" in the /boot/
loader.conf file.)

I checked the loader.rc version and it is already 1.2 (The system
was upgraded from 5.3 to 5.4 when 5.4 was released.)
The strange thing is that we have two identical servers (load
sharing mail and ldap systems) which run on the same hardware and
software. The first system was converted over to gmirror without a
hitch. This second one has the problem outlined above.
The loader.rc files are the same version on both systems.
Also, the output of:
# kldstat -v | grep g_mirror
# sysctl kern.module_path
# ls -l /boot/kernel/geom_mirror.ko
is also identical on both systems.
I'm not versed enough in the detailed workings of geom to know where
to look to find what is different between the two systems. Any
suggestions?
Thanks,
