zpool upgrade error

[netogandolfi]

Good evening, I would like to know if there is a way I can locate the pool key.

I had to update my freenas to truenas core and after updating it no longer recognizes the existing pool.

Can I recover my pool???

Hello,

was it a geli-encrypted pool?
What do you mean "no longer recognizes"? As in, it cannot be unlocked or simply doesn't see the drives as members of a pool?

Please read the forum rules (located above in red letters) and post the TrueNAS version you are now running, and please describe in detail what is going on. Please do not assume that we understand your specific issue, that is making assumptions and is dangerous and then we have to ask all sorts of questions and it takes longer to solve the problem.

Do you have a copy of your old FreeNAS configuration file? I ask because maybe you could create a FreeNAS boot drive and restore the config file and have access to your NAS again, then figure out a proper path forward to upgrade to TrueNAS. But if you upgraded your pool to a new version, you will likely not be able to use the older FreeNAS version, but it's worth a try either way.

Sorry I don't have much knowledge in FREENAS,

I'm trying to import the POOL from a client and I get the following error:

The above exception was the direct cause of the following exception:

I hope I've managed to express myself this time.

Thanks for the answers.
