Reinstall without data loss (lemmy.world)

Hi, I can't connect to my TrueNAS scale server anymore, not even through the webGUI due to me being stupid. It seems like I need to do a full reinstall and I'm very paranoid about losing data. What do I need to do so I can reinstall truenas without using data? Do I need to export my pools? I don't want to save my config, since it seems to be totally broken. Thanks in advance.

I'll be honest, I never tried it that way. But it should be possible. If you have the possibility, I'd advise to simulate that in a VM, then you'll know for sure! But basically importing zpools should even be OS agnostic, as it is an open standard that you can just install on any OS. I've heard stories about people even migrating pools from core to scale and vice versa, which is going from BSD (core) to scale (debian linux).
