I reclaimed my server today, albeit having to disable 2FA in TrueNAS for the privilege of doing so. Had to generate a new server ID, after which my server become visible again.
Claiming went smoothly, my single drive pool and my raid-z pool showed up without any issues. My data, metadata and log vdevs still show up as unused though.
I do not get an update notification though. The server is still running TrueNAS 24.10.1, to which it was updated manually via TrueNAS. I was hoping to do future updates via HexOS only.
