Hi!
In RELENG_8, gmirror is good enough to keep whole HDD pair withing the mirror.
Its performance, stability any pretty ease of maintainance allows
to use it widely.
With wide deployment of gmirror in production I've faced inability
of RELENG_8 to store kernel crashdumps out-of-the-box.
gmirror manual page documents a way to setup FreeBSD so that
it would store crashdumps again but that way involves /etc/rc.early
removed from RELENG_8. I've read about intentions - it was unsafe etc.
But we still need working crashdump support.
Easiest way is to reincarnate /etc/rc.d/early support making it better and safer
and it should support gmirror's mechanics for crashdumps out-of-the-box.
I'll tell you the same thing I told Kostik way back when I removed it.
This is the only thing that anyone has ever suggested a use for in
/etc/rc.early, and the "solution" in the man page is a hack. :)
If this is something that is necessary to do then I'd prefer to do it
properly and add an /etc/rc.d/gmirror that runs in the proper (early)
position, and then figure out the proper location in rc.d to handle the
second half of the configuration.
I'm happy to review patches. :)
Doug
