Hey Juergen,

Just to followup and say thanks, and solve the mystery for the thread... I've solved the issue. More below...

This assumes the upgrade from 2008.11 to build 111a did not
install the new grub bits, but the menu.lst file was rewritten
and now uses those zfs gang blocks, and the old grub cannot
read the file any more?   What kind of error is reported by the
grub console when you try a "cat /boot/grub/menu.lst" ?


No error.  I see the file on the screen.  This is, of course, after I've
done the findroot.

Hmm, with a VirtualBox 2.2.2 guest install and build 111a,
I can enter the grub console and cat /boot/grub/menu.lst,
without having to use findroot!

Well, in my case, grub is loaded but presumably doesn't even know which of
the partitions on the disk to operate with, right?  In your case, you've
dropped to the grub menu after loading a number of parameters, including
that there is this thing called rpool on a particular disk.

Maybe I misunderstand what the findroot is doing and prematurely did the
findroot.

I tried just now and got "Error 25: Disk read error"
(snip...)
I've just tried and yes, I can cat the splash.xpm.gz.  Any thoughts on how
to get grub back in shape on this box?

I currently have no idea what's broken on your system...


When you boot and the system stops at the grub> console:
what is reported by grub's "root" command?  Does it report
that it uses a zfs root filesystem?

grub> root
 (hd0,0,a): Filesystem type is zfs, partition type 0xbf

So, it turns out I'd burned a CD of OpenSolaris which was in the drive. I'd never used/tested it, and apparently the grub which was coming up was off of the CD, not the HDD. Since it just dropped to the console without much other info and I didn't even notice the small read from the CD drive on reboot, I was confused.

After ejecting the CD, everything behaves as expected. Troubleshooting lesson learned :)

Thanks again for the help,

- Matt
