I finally had time to (try to) read through that, and I'm having trouble locating a description of how to partition a gmirror. (The page seems oriented almost entirely to ZFS and gpart, the only mention of gmirror being in connection with swap.) I'm quite sure I don't want to attempt ZFS on a machine with only 512MB, and I'm not at all sure that a BIOS of this age would understand gpart. > It shows how to load geom modules from usb stick I had already figured out that part :) Fixit# ln -s /dist/boot/kernel /boot Fixit# gmirror load which is all I think I need until I get the mirror partitioned. > Next fdisk/gpart accordingly (don't forget to make it bootable). This is where I get stuck. I've partitioned the physical drives using sysinstall, but how do I go about partitioning gm0? > If your setup if GPT compatible, I recommend using it.

I sure did not get that impression from reading gpart(8) :( For starters there seem to be at least 6 kernel options, of which I guess I may need 3: GEOM_PART_BSD, GEOM_PART_GPT, and GEOM_PART_MBR; there's apparently no "edit" function; and one has to puzzle out what is meant by a "protective MBR" as part of understanding how to make a GPT partition bootable. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
