Pool goes offline after ZFS version upgrade message appears

[zerobizzy]

Hi everyone,

Whenever I boot up my TrueNAS system I get two error messages saying:

1:

CRITICAL
Pool Archive15TB state is OFFLINE: None
2022-12-18 02:35:46 (America/Los_Angeles)Dismiss

2:

New ZFS version or feature flags are available for pool(s) Archive15TB. 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.

So I need to upgrade the pool that way it doesn't go offline?


My main storage pool goes offline, whenever this message appears.

When I go to storage > pools: it also says offline:

I could not find a GUI button to upgrade the pool. So I tried using the shell.

I tried searching the forum for this particular ZFS upgrade error and found these commands.

How to update the ZFS?

My server is at TrueNAS-12.0-U8. How to find out what version the ZFS is on? How to update/upgrade the ZFS? Thanks.

I tried these commands but nothing really happened.

zpool upgrade

result:

This system supports ZFS pool feature flags.
All pools are formatted using feature flags.
Every feature flags pool has all supported and requested features enabled.

I also tried:

root@truenas[~]# zpool upgrade -v

result:

This system supports ZFS pool feature flags.
The following features are supported:

see the ZFS Administration Guide.

Also tried:

root@truenas[~]# zpool upgrade -a

Result:

This system supports ZFS pool feature flags.
All pools are already formatted using feature flags.
Every feature flags pool already has all supported and requested features enabled.

root@truenas[~]# zpool status

root@truenas[~]# zpool status
pool: boot-pool
state: ONLINE
scan: scrub repaired 0B in 00:00:03 with 0 errors on Tue Dec 13 03:45:03 2022

boot-pool ONLINE 0 0 0
ada0p2 ONLINE 0 0 0

errors: No known data errors

The only solution I could find is rebooting the system, and then the pool shows up fine. But whenever I shut it down, and boot it up again. The error message reappears and the pool is offline. It’s very inconvenient to boot it up twice for the machine to recognise the pool.


I am coming from a home windows server. I’m new to trueNAS but I’m completely lost. Can anyone help me? Maybe the problem is not the ZFS upgrade but something else?

Sincerely,
Zerobizzy

No, these are independent issues. The notice that your pool can be upgraded is an optional choice notice. Once updated, a pool cannot be rolled back to an earlier version, so if there happens to be a problem with TrueNAS that is requiring a downgrade, that becomes impossible. Some of us live with pools perpetually in this state; I typically upgrade ZFS feature flags right BEFORE upgrading to a new version of TrueNAS, because then I can always downgrade at least one version.

Your system is looking for a pool named Archive15TB but it cannot find it. Therefore it is OFFLINE.

Please post a detailed description of your hardware, including your drives and what you are using to attach them to your host.
