greetings,

please help me to understand what am I missing ...

I "successfully" (built/installed world/kernel without errors) upgraded
long time, fine worked root-on-zfs box from 10.0 STABLE (last built in july)
to RELENG 10.0, p11

but after reboot, loader complained on unsupported feature:
com.delfix:hole_birth and com.delfix:embedded_data

when I LiveCD'ed from 10.0 RELEASE image, zpool complained with not all
features supported, so I LiveCD'ed from the image 10.1

I was able to see and import (altroot) my zpool after what I performed
`gpart bootcode ...' (as it was advised in similar cases I was able to
google out) but it didn't help ... after that loader complains with:

ZFS: can't find pool by guid

though value of vfs.zfs.boot.primary_pool is correct and contains the
very guid of my pool ...

and in addition:

lszfs recognizes no pool
lsdev shows no zfs device=20

here, please find IPMI console screenshots (I was unable to find how to
grab text):
https://www.dropbox.com/sh/khou69n4wgadxy2/AAC9Q7sbLSPCEdB2CzQvmoGLa?dl=3D0

in /boot/loader.conf it is set
zfs_load=3D"YES"

and in /etc/rc.conf it is set
zfs_enable=3D"YES"

system was working in production long time before that

So, is there any way to fix that and what is it at all? Is it because of sw=
itching from
stable to releng?  I'm giving up in attempts to revive it ...
