Hi folks,

I've been using GEOM mirror, and plan to expand my usage.  I was wondering 
how easy it is to deal with physical moves of the component drives of a 
mirror.

Eg, I have this GEOM mirror, and I migrate the hardware.  What's now ad6
becomes ad4 and ad7 becomes ad6.  What's the recommended way to do this, 
or does it "just work" when GEOM discovers the providers in their new 
locations?

> gmirror status
         Name    Status  Components
mirror/odata  COMPLETE  ad6
                         ad7

I checked manpages and handbook but didn't see any info there.

(running on FreeBSD 6.3-RELEASE)

thanks,
-omar
