Upgrade to 11.2 from 9.10 failed... reverted... got 10.2... lost pools...

Not open for further replies.
Oct 30, 2015
Hi -

I've been running this freeNAS box since 2014 and it's been awesome!

This morning, I decided to upgrade from 9.10 and got 11.2-BETA1 (from the stable branch) installed. I upgraded b/c my jails (applications) have been locking up at night requiring a plugin reset daily.

Anyway, after the upgrade completed, I no longer had gui-access to my jails or my installed plugins. I decided to revert back and selected the 9.10 STABLE branch... and got 10.3STABLE... without any ZFS pools mounted... (I have two.) I also have an ngnix error so the gui is no longer available.

Can someone please explain, or point me at a resource, that carefully and patiently explains how to re-mount the existing pools?

Other questions:

Can I downgrade to 9.10 from the command line -- would doing so automagically recover my pools?

Thanks for any help - yes, I'm pretty much a noob with FreeNAS -- it's always worked so well, I've never had to do anything more complex than gui level stuffs so please make no assumptions about what I know. ;)

You shouldn't have been able to select a lower train number. If you did that from BETA1, please create a report at bugs.freenas.org.

To revert, reboot back into your 9.10 system. It should still be in the boot menu unless you manually deleted that boot env.

Thank you for the fast reply!

I've not deleted anything... I also should have mentioned that this is a headless system...

Can you please explain how to (re)boot into 9.10 from the command line?



beadm list will show your boot env.
beadm activate boot_env_name instructs the system to boot into the specified boot_env_name on next boot.

Thanks! I found this info in another post and was able to recover back to the 9.10STABLE release!

If I want to u/g to version 11, then, I should choose 11-STABLE instead of 11.2-STABLE so as to avoid the original problem? (Losing the installed plugins and jails)



Going from 9.10 (based on 10.x FreeBSD) to 11.x (based on 11.x FreeBSD) is an ABI change. This means that you really do want to reinstall your apps. Most users do a fresh plugin or jail install, grab their existing configs, test everything is A-OK, then delete the old plugin or jail.

If go from 9.10 to 11.x:

1) Is there a Legacy GUI in 11.x that shows the old jails. Am correct in assume I can continue to use my 9.10 jails and apps in 11.x but just can't update them?

2) Did I hear rumors of a script that would migrate jails to the new 11.x iocage format?

3) From above it sounds like reinstalling the plugin after migration might be the cleanest route, then deleting the old jail once you've confirm operation of the app in a new iocage jail.

4) I can always recover my 9.10 system from the "Upload Config" tab on the system menu as long as I don't upgrade my Zpool?

1, click logout and then click on legacy ui at the bottom of the log in prompt
(Also you can't MAKE anymore warden / old jails but you can check the details, stop / start them and even delete them)
2, yes and it works half ok - it's not flawless but it does work, 3 of my 6 jails, I used that script and they run fine (warden 100% disabled for nearly a month now)
This thread should help you.
3, This will totally be the 'cleanest' method - but depending on the plugin the migration script is a good stop gap.
4, I wouldn't bother with 9 anymore, that's crazy talk, if you go back for some reason, 11.1 U5 is the way to go.

I'm personally pretty happy with 11.2 Beta2, there's been a bit of fiddling but it's now behaving well
