ZFS zpool import problem from ubuntu

[Alain De Vos]

When i try to import my freebsd zpools i get the error:
state: UNAVAIL
status: The pool was last accessed by another system.
action: The pool cannot be imported due to damaged devices or data.

Altough the zpools are healthy in freebsd.

And the error:
state: UNAVAIL
status: The pool uses the following feature(s) not supported on this system:
com.delphix:head_errlog (Support for per-dataset on-disk error logs.)
org.openzfs:zilsaxattr (Support for xattr=sa extended attribute logging in ZIL.)
action: The pool cannot be imported. Access the pool on a system that supports
the required feature(s), or recreate the pool from backup.
This error is more difficult as i enabled "newer features" by accident doing "zpool upgrade".

Yeah, you are screwed. You need to be very careful when creating pools that you want to be accessed by other OSes, you need to exclude all features not supported by the other OS.

linux-zfs & freebsd-zfs seem to be only compatible when you take the inner union of the supported features on both OS's. Not very clear how to create the zpools with features disabled for both OS's.
