Now my system boots and if you mean the freebsd-boot partition, that isn't part of zfs. That is just an empty partition to hold gptzfsboot. So, that isn't relevant. This does work for me... I still haven't been able to produce a non-working system. Other than the case where the BIOS doesn't pick up all the drives. I've built booting systems with single and multiple root devices as well as raidz1 or raidz2. I'm not saying that there isn't an issue, just that I haven't been able find a failure that I can reproduce. robert. > >ZFS: i/o error - all block copies unavailable > error is missing. > But I haven't really finish boot part. > Now I'm getting: > Trying to mount root from zfs:zroot > ROOT MOUNT ERROR > > So I'll have to figure out what went wrong during fixit installation, > maybe some typo > > On 10/28/09, alteriks@gmail.com wrote: > > On Wednesday 28 October 2009 12:10:10 you wrote: > >> I think that is unlikely.
