zfs discuss - Oct 2009 - zpool import single user mode incompatible version

I know this is opensolaris and Solaris, but I''m stuck...

I want to demonstrate to my client how to recover an unbootable system from a
zfs snapshot. (Say some dope rm -rf /kernel/drv...) Running Solaris 10 U8 sparc.

Normal procedures are boot cdrom -s (or boot net -s) 
zpool import rpool
zfs rollback <snapshot>
reboot and all is well

I''ve done this before with earlier rev''s of Sol 10.

When I boot off Solaris 10 U8 I get the error that pool is formatted using an
incompatible version. Status show the pool as "Newer Version"

I know Update 8 has version 15, but it looks like the "miniroot" from
the install media is only version 10.

This is not good.

Any advice? I am already thinking about installing U7 on my test box to
demonstrate. Glad I haven''t rolled out u8 into production.

Thanks,

Paul

Not to be a jerk, but is there a question in there?  The system told you
exactly what is wrong, and you seem to already know.  You''re booting
from an
old cd that has an old version of zfs.  Grab a new iso.

How would you expect a system that shipped with verison 10 of zfs to know
what to do with version 15?

It might be that I can''t read but does OP not state he is booting off 
Solaris 10 update 8 DVD?
What can be newer than that one? If the miniroot really only supports 
ZFS v10 then this is indeed not good (unworkable/unusable/..)

Assuming he didn''t accidentally burn the wrong media... and the 10u8
does in
fact have 15 as the default version, but 10 as the mini-root (that sounds
more than a bit odd to me), it''s a matter of simply grabbing an
opensolaris
ISO instead to do the exact same thing.

OK, my bad. I was looking at the WRONG bootserver, on another network.
Shared out the U8 DVD, boot net -s, and can import the zpool.
