Is there any good beginner friendly documentation for zfs? I've started using it as a testing/learning NAS with a raspberry pi (cloning my google library to immich). It has not been a clearly easy process and errors are very much not clear. I recently extended a single drive to 2 and now I can't import due to corrupted metadata and reports bad disk but smartctl reports all fine. Stack overflow is all over the place and reddit is... reddit. So is there a good goto place for these kinds of issues? I suspect this will be far from my last one.
