Export Zpool for use with OpenZFS on OSX

[witchbutter]

My freenas box was built on older hardware which seems to be failing, and rather than build another cheapo noisy set up I am just going to pull my zpool and put it in a thunderbolt enclosure. I know from previous attempts that there are some unique ZFS attributes used by either FreeNAS or FreeBSD in general. Does anyone know how to check and modify the pool properties to make it less of a hassle to import elsewhere? If not I will be stuck with trial and error.

you can not downgrade your pool.

On each system, run zpool upgrade -v to see their feature flags. Don't forget the -v

If you use the latest OpenZFS on OSX (1.3.1-r2) it will be able to use the FreeNAS 9.3 pool with no issues. OpenZFS on OSX supports all the feature flags that FreeNAS 9.3 can possibly use.

Just finally got around to doing this and sure enough the pool cannot be imported because of the features:

$ sudo zpool import -f st4
This pool uses the following feature(s) not supported by this system:
com.delphix:hole_birth
com.delphix:embedded_data
cannot import 'st4': unsupported version or feature
$

You need to upgrade your OpenZFS on OSX. The latest version definitely supports those flags.

Thank you the 1.3.1-r2 version works.
