Public bug reported: I have upgraded my dual boot laptop (Xubuntu 19.04 on ZFS) to 19.10, I only had a minor problems:
The system started scrubbing the exisisting datapools. In the scrub I have been notified, that my datapool did not support all new features and that I had to upgrade the datapool. Of course I followed that advice enthusiastically and now the second 18.04.3 OS does not recognize the upgraded datapool anymore. I found out I can’t disable the culprit features. I think there should be a more specific warning in the "zpool upgrade" for stupids like me. Only upgrade the datapool, if all OSes on the PC have been upgraded to zfs 0.8. ** Affects: zfs-linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1843298 Title: Upgrade of datapool to ZFS 0.8 creates a problem if dual booting To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zfs-linux/+bug/1843298/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
