And nothing changed.
Probably I have 2 questions:
1. Is it possible to fix it and continue using ZFS
2. If I just wipe my ZFS drives, reboot and format them in ext4 (as example) will I see this ZFS error? Because now I do not have
any ZFS plugin or libraries and anyway see error
If you have zfs drives, you need to have the zfs plugin installed. Otherwise, you will get the zfs backend error (as we have seen).
If you wipe the zfs drives (use wipefs -a) then you should not see the error.
