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=
