Sorry, you were right about the meaning of import/export and rmdir, but my excuse is, that it has been very early in the morning.
However I have the same update problem on an ext4 installation of Ubuntu 19.10 on the same laptop. It gives the same error on two zfs modules, but of course without the zfs-initramfs module. So that has nothing to do with, how that system has been booted or which "How-To" has been used to boot from ZFS. It is just a very standard zfs installation on ext4 with two datapools and that is not an unofficial, experimental setup. For proof see the results on an update this morning in the file zfs- ext4. I purged zfsutils-linux and reinstalled it again on the ext4 system. After rebooting and importing the datapools the first time after the purge again, everything worked fine with the new version 12 of zfs. Unfortunately I can't use that trick, when I boot from ZFS. I think that proofs, that there is nothing wrong with the datapools itself or ZFS itself. So both version 11 and 12 of ZFS works fine, but you have a faulty update process for standard zfs and the same fault occurs on my version of "Boot from ZFS". ** Attachment added: "zfs-ext4" https://bugs.launchpad.net/ubuntu/+source/zfs-linux/+bug/1846424/+attachment/5295464/+files/zfs-ext4 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1846424 Title: 19.10 ZFS Update failed on 2019-10-02 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zfs-linux/+bug/1846424/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
