Hi again,
Thanks, but it didn't help me much. This time it's definately because
I have no clue though. ;)
I'm doing this in a virtual machine, so adding disks and such is easy.
Understanding it all isn't, though.
I currently have a 7.0-CURRENT machine, with a single disk (ad0)
and ZFS up and running, with no pool.
My goal is, if possible, to create a pool over three (virtual) disks,  
using
RAIDZ, and move everything (again, except /boot) there, and have it  
all work.
The instructions are quite incomplete, though, and the page doesn't  
say if
doing this even should work.

Anyway. Could someone lay out some simple steps? I've tried creating
the new 'a' partition, copying /boot and create a symlink, so far so  
good.
Except when I reboot the loader complains about it (I'm guessing because
/boot is a symlink to another partition that it doesn't know about?).
Also, I don't know how to get my stuff over to ZFS - singleuser and  
cp -Rp?

Thanks in advance,
Thomas
