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'm not sure exactly what your setup is, if you have data in the OS pool that might be gone, unless you can boot the system from a stick and mount that disk to copy data over. Zpool export isn't strictly necessary.

If your data is in a different pool then it should be theoretically easy to just import that pool in a new install.
