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, Anselmhelp
