Hello,
I run 7.1-PRERELEASE, its a home server.
today morning after a power failure, the rebuild my root gm0 failed on disk ad4.
The messages were:

stopped.
I read http://www.eztiger.org/2008/08/removing-and-re-adding-a-disk-in-gmirror/
hoping that the rebuld failure was temprary
and so i tried to just run
# gmirror forget gm0
# gmirror insert gm0 ad4
The correct order of commands is:
atacontrol list
gmirror list
gmirror forget gm0
gmirror clear -v ad4
gmirror insert -v gm0 ad4
