Lost vdev after upgrade

Before upgrading I installed truenas scale 24.04.2.3 using a USB stick, the storage pool is a striped layout consisting of two different sized hdd’s, leaving one ssd unused.

After backing up the system configuration, I tried to upgrade to 24.04.2.5 via the button on the web page, but after auto-reboot, the system boot was not found.

Then i try to install 24.10.1 on the ssd and uploading the backed up system configuration via the web page, the pool was offline after rebooting again, with 2 hdd Unused Disks and no vdevs in the pool.

How do I restore the pool?
