SOLVED Warnings 'ZFS upgrade' and 'Root password disabled' don't disappear

[itet]

Hi I have updated my systems to 22.12 and on some systems the following warnings won't disappear.

WARNUNG​

New ZFS version or feature flags are available for pool 'tank'. Upgrading pools is a one-time process that can prevent rolling the system back to an earlier TrueNAS version. It is recommended to read the TrueNAS release notes and confirm you need the new ZFS feature flags before upgrading a pool.​

I have already upgraded the ZFS version.

WARNUNG​

Root user has their password disabled, but as there are no other users granted with a privilege of Local Administrator, they can still log in to the Web UI. Please create a separate user for the administrative purposes in order to forbid root from logging in to the Web UI.​

The Root user has password.

Code:

# zpool upgrade boot-pool

Create a new user to login into UI, see post.

zpool upgrade boot-pool already down as you can see no info about available upgrades

 

[Daisuke]

That was the only pool it required upgrade for me, you’re correct, you should see a warning when you run zpool status. I don’t see any pool warnings in my UI, do you still see them?

Yes the info is still there

 

[Daisuke]

If you ran already zpool upgrade tank, reboot the server. The error should be gone from UI. If you did not ran the upgrade, please do.

Code:

 ⚡ root@TrueNAS01  ~  zpool upgrade tank
This system supports ZFS pool feature flags.

Pool 'tank' already has all supported and requested features enabled.

And after reboot warning still there.

Open a ticket with iX and report the issue.

Upgrading the zfs features of the boot-pool is discouraged, because it prevents you from rolling back in case of incompatibilities.

Thanks for this info, this is very good to know.

The rollback you mention has nothing to do with boot-pool, you cannot rollback after a zpool upgrade, period. Once you upgrade to a new zpool version, is expected to upgrade your pools also.

That can be a very risky strategy and I wouldn't reccomend that action to other users. If you upgrade the feature flags on your storage pool and run into issues you can't roll back your installation to a previous boot environment. Upgrading the feature flags is a one way process.

Other forum members much smarter than me have suggested not upgrading the feature flags on the boot pool since they will never be used on the boot pool and it is unknown as to any sort of compatibility issues the system may encounter if you do.

 

[Daisuke]

Upgrading the feature flags is a one way process.

I totally agree with that statement. I always upgraded all FreeNAS/TrueNAS pools running on Dell enterprise servers since 2011 and never encountered an issue. But like you said very well, is best to follow your own guidelines.

long time ago solved with TrueNAS update.
