Hi,

I'm experimenting with a ZFS only system and booting from it in VirtualBox. 
Thanks to various mails and forum posts from the net I have a working scenario 
with booting from a ZFS mirror. However, I can't get the thing to work with 
raidz with the exactly same setup, except that the pool is now raidz instead of 
mirror and there is one more disk. I feel sure I have all the stuff with 
partitioning, boot loader installation, etc. right. I tested this with version 
8.0-RELEASE on 64bit.

Now, before I go into detailed explaining, is raidz really supported? I always 
get the following error after it says "FreeBSD/i386 bootstrap loader, Revision 
1.1":

ZFS: i/o error - all block copies unavailable
ZFS: can't read MOS object directory
(repeats a lot)
Can't find root filesystem - giving up
can't load 'kernel'

I think the "MOS" message comes from zfs_mount_root() in 
/usr/src/sys/boot/zfs/zfsimpl.c. I asume that is the point when /boot/loader 
has been loaded and now wants to load the kernel into memory. After that error 
I'm in the loader prompt. When I try to load any file I always get the same 
error as above.

Anyone any ideas?

Thanks,
Anselm_______________________________________________
