I was running FreeNAS 9.10 for 10 years on a HP MicroServer N36L Athlon2 1,3GHZ DualCore with 8GB of RAM and I decided to do a fresh install of trueNAS 12. (TrueNAS-12.1-MASTER-20210.)

After the installation I tried to import my old pool via WebGUI but I received the following error:


Code:

I tried to do a service middlewared restart and import after it, but without any success.

Try

Code:
zpool import
# copy pool name
zpool import -o altroot=/mnt <name>
zpool export <name>


Then try from the UI again.

Well the experience on the GUI was different and I think I got one step further but I still got this error:

This was the output of the zpool import:

 action: The pool can be imported using its name or numeric identifier, though
    some features will not be available without an explicit 'zpool upgrade'.

Ok, let's try
Code:
zpool import -o altroot=/mnt ZFSPool
zfs set mountpoint=/mnt/ZFSPool ZFSPool
zpool export ZFSPool


Then the UI again.

hmm the second one gave me an error:

root@truenas[~]# zpool import -o altroot=/mnt ZFSPool
root@truenas[~]# zfs set mountpoint=/mnt/ZFSPool ZFSPool
cannot unmount '/mnt/ZFSPool/jails_2': unmount failed

Weird. Please with the pool still imported:
Code:
zfs get -r mountpoint ZFSPool
zfs unmount -f ZFSPool/jails_2


And then retry:
Code:
zfs set mountpoint=/mnt/ZFSPool ZFSPool
zfs export ZFSPool

Some dataset seems to have a mountpoint of /data/zfs set. So please import in the CLI again and post the output of
Code:
zfs get -r mountpoint ZFSPool

as I asked in my last message. Thanks.

OK ... this is probably not about your pool. /data/zfs seems to be the location where TrueNAS stores the zpool caches. Why it does not exist on your system - no idea. But here on mine it's a plain directory on the boot pool.

So export again if you have not done so already, and use this command: mkdir -p /data/zfs before trying again to import from the UI.

BTW: if this finally works out I would go straight to TN 13. No reason to start with EOL software if you are doing a fresh install, anyway.

Fingers crossed ...

yes! it worked. thank you so much!
The reason that I installed TN12 was that I only have 8GB of ram and I was under the impression that TN13 requires more.

I also got the message that I should upgrade my pool... not sure if I should though..

Only if you are confident you will stay on your current version. But you are not going back to 11, are you?

Seriously, TN 13 will not require significantly more memory than TN 12. 8 G is tight for both but will probably work.
So, I'd recommend upgrading your pool for 12, then trying the upgrade to 13 but not upgrade your pool for that, so you can roll back.

HTH,
Patrick

ok I will do that.
Is there a way to upgrade to 13 via WebGUI or do I need to boot from an installer?

Sorry but I must be doing something wrong... when I go to Updates there are no updates available and I also can not change the train.

Current Train: TrueNAS-12.1-Nightlies - Release Train for TrueNAS 13.0 [release]

That's weird. Changing trains and upgrading should be possible. Possibly that's because you installed a 12.1 nightly instead of a 12.0 release. Make sure you pick a release image for 13, preferrably 13.0-U5.

so the manual update via WebGUI stopped at 67% and nothing happened... so I guess I have to do the old "boot from usb stick" way..
