I set this while the OS is running.  GEOM_MIRROR responds every 5
seconds....

GEOM_MIRROR[1]: Disk ad6 (device gm0s1) marked as clean.
GEOM_MIRROR[2]: Metadata on ad6 updated.
GEOM_MIRROR[1]: Disk ad6 (device gm0s1) marked as dirty.
GEOM_MIRROR[2]: Metadata on ad6 updated.

Can I get gmirror to attempt to connect to ad4 again?  I tried an
atcontrol reinit 2, that didn't do it.  I also tried gmirror rebuild
gm0s1 ad4, but gmirror said: "No such provider: ad4".
