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. Comments? Eugene Grosbein
