ZFS upgrade problem (zpool version 14)

V

val

Hi to all!

After upgrading 8-stable to zpool version 14 OS can't be booted:

Code: 
ZFS: unsupported ZFS version 14 (should be 13)
NO ZFS pools located? can`t boot
What's wrong with ZFS? How to fix?
 
You've gone too far into the future, and are trying to access untested features. ;) One of the dangers of being an early adopter.

You'll want to post to the freebsd-fs mailing list. Maybe someone there will know how to fix this.

Do you use zfs for your rootfs?

Yes, gpt partions.

you could try to start the fixme shell on the dvd and recompile the zfsbootloader.

http://wiki.freebsd.org/RootOnZFS/GPTZFSBoot:
Code: 
 Fixit# echo 'LOADER_ZFS_SUPPORT=YES' > /etc/src.conf
 Fixit# mount -t devfs devfs /dev
 Fixit# export DESTDIR=""
 Fixit# cd /usr/src/sys/boot/
 Fixit# make obj
 Fixit# make depend
 Fixit# make
 Fixit# cd i386/loader
 Fixit# make install

maybe this will make the bootloader aware of zfs v14.

Thank you for reply, but I reinstall whole world after upgrading zpool, so I think recompiling zfsbooloader doens't help me in this case.
 
Yes!
Need to update bootstrap code into partition scheme's metadata. Updating only gptzfsboot enough.
Code: 
gpart bootcode -p /<whereis from v14>/gptzfsboot -i 1 ad4
 
I understand what you're suggesting, but how can you get to ZFS v14 boot code when you cannot boot the v14 pool?

The 8.0-RELEASE installation media will have only v13 bootcode, yes?
 
I had the same issue and only a stable 8 snapshot from December.
Used fixit to install base and src to a memory file system, chroot && csup to latest stable :e

I use live cd (from here http://mfsbsd.vx.sk/) with zfs enabled, mount my pools, and simply take bootcode from my newly built world.
