Solved From 12.2 to 13.0-RC2 : do I need to keep opensolaris.ko ?

[tuxador]

Hi I just successfully upgraded my workstation to 13.0-RC2, and since this version uses openzfs I did a zpool upgrade , so I thought that the opensolaris kernel module is no more needed.
Can I safely remove opensolaris_load=YES from my /boot/loader.conf ?

First, even on 12.x you can remove opensolaris_load=YES from /boot/loader.conf - it will be automatically loaded when needed.

Second, on 13.x with OpenZFS 2.0 loading of opensolaris.ko glue is not needed anymore. You can load it but it will not be used anyway.

Hope that helps.

It's crystal clear ?. Thank you.

Why opensolaris still in 13 and 14?
Who except old zfs used it?

I guess that's a question for the freebsd-current ML? It's a GOOD question for sure!

Still receives regular commits. Looks mostly DTrace related.

Hypothetical question for the future.
When let's say 14 comes out is the upgrade procedure from 13 when you use openzfs:
--------------------------------------------------
make world
make kernel
make installkernel
make installworld
etcupdate
make openzfs-kmod
install openzfs-kmod
make openzfs
install openzfs
make nvidia-drivers
install nvidia-drivers
reboot ?
---------------------------------------------------

It's just the same as upgrading 12 to 13, or any other major version upgrade for that matter. You should stop using sysutils/openzfs-kmod, it is a development branch of OpenZFS. You do NOT need it.

 

[Alain De Vos]

By accident i had upgraded my zpools with openzfs. As such i need to load it because the newer features are not understood by the older freebsd-zfs.
Once all the zfs features of this zpool are in freebsd-zfs i can remove openzfs.
Probably in one of the newer zfs releases.

You can test your pool with 14 now and probably stop using sysutils/openzfs-kmod after migration on 14.

Yes. You are right.
