Unfortunately it don't work. Error is the same as before: ZFS: i/o error - all block copies unavailable ZFS: can't read MOS ZFS: unexpected object set type 0 ZFS: unexpected object set type 0 FreeBSD/i386 boot Default: pgpool:/boot/kernel/kernel boot: ZFS: unexpected object set type 0 This is 7.2-STABLE, amd64. My test procedure: 1. I fully synchronized these zfsboot-related directories with -CURRENT: src/sys/boot/i386/zfsboot src/sys/boot/zfs src/sys/cddl/boot/zfs 2. I applied Matt Reimer's zfsboot.c.patch3 patch: # cd /usr/src/sys/boot/ # patch < /path/to/zfsboot.c.patch3 3. Then I did: # make clean; make cleandir # make obj ; make depend ; make # cd i386/loader # make install # cd /usr/src/sys/boot/i386/zfsboot # make install # sysctl kern.geom.debugflags=16 # dd if=/boot/zfsboot of=/dev/da0 count=1 # dd if=/boot/zfsboot of=/dev/da0 skip=1 seek=1024 # reboot 4. Result: error shown above. Thanks! -- am
