OK - just rebooted for a bit to play around. From the grub CLI, I ran 'find /boot/grub/menu.lst'. It determined that was on hd0,0,a, so I ran 'root (hd0,0,a)' and changed the findroot line in my grub config to that as well. That didn't help a bit...
So I booted the b117 DVD, as I remembered seeing a single-user shell option there. I get into the single-user shell, and it auto-detected my zpool. It also detected the boot-archive as out of date and graciously offered to update it for me. I allowed it to do so, rebooted and now I have (surprise surprise!) the same error as I had with the b117 installation - boots straight to grub command line with checksum verification failed happening when I try to access anything on the aforementioned partition. I'll probably play around with it a bit more tonight (have to get some real work done for now...). Any more ideas? -- This message posted from opensolaris.org
