Re: freebsd / gpt boot
The following worked for me on 8TB array: Add slices as needed (modify sizes as required): gpart add -s 128K -t freebsd-boot da0 gpart add -s 1G -t freebsd-ufs -l root da0 gpart add -s 10G -t freebsd-swap -l swap da0 gpart add ... Then for installing the bootcode: gpart bootcode -b /mnt2/boot/pmbr -p /mnt2/boot/gptboot -i 1 da0 From re-reading you initial post the problem seems to be that its not mounting root correctly is that the case, as you don't explicitly say what the error is your getting?

The initial pre-loader (boot0 I think? -- i'm not sure what this is called) is unable to find loader at /boot/loader nor can it load /boot/kernel/kernel Is the partitioning done correctly (have you created a small boot partition, 15 sectors is enough for booting from ufs, but the tutorials I've found deal mainly with booting from zfs and they recommend 128 sectors to make future bootcode changes easier)? gpart add -b 34 -s 128 -t freebsd-boot -i 1 da0 Have you embedded the correct boot code? gpart bootcode -b /boot/pmbr -p /boot/gptboot -i 1 da0 (for booting from ufs). or gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 da0 (for booting from zfs). You may also need to set it active by gpart set -a active -i 1 da0 And of course, substitute your arrays device node for da0 in my examples. Copying /boot/loader to /loader allows me to enter /loader at the boot: prompt and the loader will load, however, its unable to load the kernel. If I do an ls at the loader prompt I can see boot listed as a directory (with a d before it) Trying to do ls boot inexplicably it says boot: not a directory re-applying my /boot/loader.conf settings (for some reason vfs.root.mountfrom=ufs:/dev/label/root is required, or else I get a mountroot) and then: load /kernel boot does work, and lets the system boot normally and everything is as expected (/boot is a directory etc). Anyone have any ideas about either of these things (the vfs.root.mountfrom is minor i guess but i'm curious if they are related?)

Do you have options GEOM_PART_GPT in your kernel? It's a longshot, as without it you probably wouldn't get as far as you do. It's included in the 8.0 GENERIC kernel, but in case you have a custom kernel whose config you imported from a previous version, it may be worth checking. Yes, it is in there, but I don't see that affecting the boot0 or loader.. -Adam You're right. Shouldn't affect anything before the kernel. Like I said, a longshot. I'm out of ideas. Hope you solve it. Rolf P.S. I just realised I'd been omitting the list in my replies.
