freebsd / gpt boot

[Steven Hartland]

There's already a thread about this last week, which contains the info you need to set this up.

The only thing I'd warn you about is to ensure you use the DVD not the CD as the CD doesn't have
all the things you'll need on it.

    Regards
    Steve

Hi,
I'm trying to setup a system with a very large RAID array (total ~10TB), I would ideally like to have the system boot directly off 
that 10TB array, so i'm trying to get the system setup with GPT but running into an issue.


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

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?)

Thanks in advance,

-Adam
