What do the outputs of "zpool upgrade" and "zpool upgrade -v" show on
the opensolaris host?
The first will give you the current version of the pool on-disk, and the
second will list what b134 is capable of.
"zfs upgrade" and "zfs upgrade -v" will do the same for the zfs
filesystem version, although this seems to change less frequently than
the zpool version.
Assuming your problem is truly that the on-disk version is higher than
that supported by your current snv_134 kernel, and given that zpool and
zfs versions cannot be downgraded, you're left with 2 options:
1) Recreate the pool and restore from backup (you've already said
you don't want to do this, so...)
2) Upgrade OpenSolaris to a later build using the /dev branch.
However, no dev packages have been released to the IPS repo beyond b134,
so you have a couple of options that I can think of:
a) Build the ON gate from source, then use "onu" to upgrade a new BE
with the freshly built binaries. I believe the Developer's Reference
Guide gives details on this (see
http://hub.opensolaris.org/bin/view/Community+Group+on/devref_toc ).
b) Upgrade from pre-built packages. http://genunix.org/ may help
here - I see a note on Jun 14th that Rich Lowe has posted a package
depot of onnv_142, but your mileage may vary with this.
Hope that helps,
Brian

Hi there,
I have two external USB disk drives in a zpool mirror configuration that I
would like to move between my Linux box (running zfs-fuse-0.6.9) and my
OpenSolaris home server (running snv_134).
I created the zpool on Linux, but it seems like zfs-fuse uses a newer version
than what is available on my OpenSolaris box:
[SNIP]
l...@kallisto:~> pfexec zpool import
pool: mypool
id: 4510346300987862165
state: UNAVAIL
status: The pool is formatted using an incompatible version.
action: The pool cannot be imported. Access the pool on a system running newer
software, or recreate the pool from backup.

Is there a way to update to a more recent version of ZFS on the OpenSolaris
box? I'd like to avoid having to re-create the pool again as it contains
several hundred gigabytes of data...
Thanks in advance for any info or pointers!
Bye,
LenZ
