I have created a pool on external storage with B114. Then I export this pool and import it on another system with B110.But this import will fail and show error: cannot import ''tpool'': pool is formatted using a newer ZFS version. Any big change in ZFS with B114 leads to this compatibility issue? Thanks Zhihui -------------- next part -------------- An HTML attachment was scrubbed...

You can also use ''zpool create -o version=X'' to create a pool using an older version. - Eric -- Eric Schrock, Fishworks http://blogs.sun.com/eschrock
