Hi,
I have used this setup guide (http://wiki.freebsd.org/RootOnZFS/GPTZFSBoot/RAIDZ1) line by line with the 8.2-RELEASE DVD for amd64 to install a VirtualBox guest for testing.
The only difference to the setup guide: I use a SAS controler, so devicename is da0, da1, da2 instead of ad0, etc. I tried it with a SATA controler as well, but no differences.
After reboot, I get the following error from the loader:
ZFS: i/o error - all block copies unavailable
ZFS: can't read MOS object directory
Can't find root filesystem - giving up
ZFS: unexpected object set type 0
ZFS: unexpected object set type 0
FreeBSD/x86 boot
Default: zroot:/boot/kernel/kernel
boot:
ZFS: unexpected object set type 0
FreeBSD/x86 boot
Default: zroot:/boot/kernel/kernel
boot:
I hope someone can give an hint, what's going wrong here.
Thanks in advance
Wolfgang
