Hi, I'm trying to install CURRENT a single drive ZFS on root setup using the guide located here: http://wiki.freebsd.org/RootOnZFS/GPTZFSBoot This is on an amd64-based Acer 5516 laptop. I'm able to complete the installation, however, when I boot, the system stops at the boot loader with several "error 1 lba xxx" (where xxx is some large number) errors and the "ZFS: i/o error - all block copies unavailable" error. When I issue the "status" command at the boot loader, I see only the GPT partition and the ZFS pool. Should I also see any physical devices? I strongly suspect that the BIOS on this laptop is up to some sort of chicanery but it's hard to say so definitively since I can install and boot to a regular UFS-based FreeBSD installation. I've confirmed this on 8.0-RELEASE and 9.0-CURRENT. I've also made sure to delete any UFS and GPT partitions as well as any ZFS pools before installing to be sure that I'm installing on a clean disk. Also, I've tried building the bootloader (even though the guide said it's depreciated as of 8.0-STABLE and 9.0-CURRENT) as well as installing the boot blocks, both to no avail. Any ideas and/or suggestions would greatly be appreciated! Thanks, Chris
