Jumpstart and zpool version mismatch

I have a jumpstart server with Solaris 10u10 boot media, it also has the
patches installed for Flash Archive version 3.0.
SUNWjet version 4.7
JETzfs version 1.0.3

I have a flar created from a T5120 with 142909-17 kernel patch on
Solaris 10u9, zpool version is 22, zfs version is 4.

I am trying to restore the flar onto a T4-1. Everything goes fine until
the reboot and I receive the following:

I boot into failsafe and it finds the rpool and auto imports it. From
there I run "zpool upgrade" and it says the zpool version 29.
I run "chroot /a /bin/ksh" and then run "zpool upgrade" and it says that
the system is running at zpool version 22 and can not import the rpool.

Now I believe the reason is during the jumpstart install when it creates
the rpool it just does it blindly and does not take into account the
version of the zpool the flar can support. I would think this would be
part of the make_client when creating the client from the template.

I have poked around the SUNWjet/Product/zfs and
SUNWjet/Client/hostname/directories, didn't see to much there but kind
of in a hurry.

So the last test, I started the jumpstart install process, broke out of
the installer, created the zpool with the -o version, verified with
zpool upgrade, then ran suninstall but it seems it recreated the rpool.
I thought I saw code in JETzfs that is supposed to do an import if it
exists.

Any help would be greatly appreciated.

I need to be able to have the Solaris 10u10 as the jumpstart media and
support flash archive versions 3.0. I also need it to be able to support
from zpool versions 22-29 atleast. I haven't found another server yet
with a lower zpool version than 22.

Also I am not able to patch the server up to be able to support zpool
version 29 prior to creating the flar, nor do I want to apply the patch
after the jumpstart install.


Thanks,
Chris
