Oracle has no input into its > development as far as I can tell. I'm not sure that David S is referring to. Sun open-sourced zfs and it was at zpool version 28 when Oracle closed-sourced it. So the cat's out of the bag up to v28. But the Solaris version's currently 36 (IIRC) and, in openzfs, you can enable extra, post-v28 features on a case by case basis. [Someone said up-thread that you couldn't expand a pool (or add disks to a pool). That's incorrect. You can add a same-type vdev to a pool.]
