Migration from Legacy to UEFI

[ewans]

Hello,
I'm using FreeNAS several years on my old computer (just boot flash drive and one data hard drive, one pool, plex jail). Now I bought new Asrock motherboard, but this MB can only UEFI boot and my boot flash drive uses legacy.
Before start I updated on TrueNAS 12.0 and made backup.
I tried to make new installation drive and new UEFI boot system, but after I import my backup, my pool is offline, but disk is visible.
I tried:

Code:

root@freenas[~]# zpool status -v
  pool: boot-pool
 state: ONLINE
config:

        NAME        STATE     READ WRITE CKSUM
        boot-pool   ONLINE       0     0     0
          ada0p2    ONLINE       0     0     0

errors: No known data errors
root@freenas[~]#

which shows boot pool only, but in disk list is ada1 - my data drive

Code:

root@freenas[~]# geom disk list
Geom name: ada0
Providers:
1. Name: ada0
   Mediasize: 500107862016 (466G)

   ident: WD-WCC4N9JYUVDJ
   rotationrate: 5400
   fwsectors: 63

Now I noticed critical alert, but I'm not sure if it's cause or consequence:

Code:

CRITICAL

Can you help me import pool into system? I'm not an advanced user, I've some linux knowledge, but on FreeBSD is everything slightly different.
Thank you

Can you help me import pool into system?

Have you already tried Storage | Pools | Add | Import existing pool ?

You can check that the pool is recognised by testing with:
zpool import

which will list the pool without actually importing it.

There's a reasonable chance that you didn't export your pool on the original install (and if your config backup had restored properly, you would not have needed to), so the pool will need to be imported with the -f flag.

at CLI:
zpool import -f <poolname>

Then:
zpool export <poolname>

Then import it from the GUI.

I'm not at home now, but I think I tried

Code:

zpool import 

with message like "Nothing to import". I can try to rebuild hard drive to my old "server" (I still have boot flash drive too) and try

Code:

zpool export <poolname>

I'll post progress, thank you.

Hello,
even on my old server
root@freenas[~]# zpool import no pools available to import
Probably I brick my pool when I tried to import them during install :-(
I was quite confused with 2 flash drives for start from scratch and I probably break my filesystem when I hit yes on screen bellow (with choosen my hard drive):

because I expected this screen: (I want to upgrade legacy on uefi (How dumb I was.))

and on screen bellow I quit the installation, but probably late...

I think there is no possibility to repair this problem, am I right? Did I lost my pool as same as my data? Is there any possibility to recover (backup) data in some linux distro?
Thank you for answer
