The size of the pool is not particularly relevant. It sounds like you think I'm asking you to backup and restore your pool, which I definitely am not. A pool "import" is somewhat like "mounting" a pool (though it's not literally mounting, because mounting is something that happens with filesystems). An "export" is similarly like unmounting.
As I said, those instructions were intended to be a _safe_ way for you to return your system to working order. It's likely not necessary to boot into recovery mode, or export the pool to resolve this. The key thing is that /vms and /hp-data are non-empty. Fix that and your mounting issue will be resolved. I was suggesting you go into recovery mode and export the data pool to avoid the potential for accidents. But really, if you only use `rmdir` rather than `rm -rf`, you should be safe. Root-on-ZFS installs are not supported by Ubuntu or Canonical. Canonical is working on providing experimental support for Root-on-ZFS in the installer for 19.10, which should be out this month. I do not work for Canonical. I provide the upstream ZFS-on-Linux Root- on-ZFS HOWTOs for Debian and Ubuntu as a volunteer project. I have never guaranteed any in-place upgrade path. And you likely didn't follow my HOWTO anyway, as your dataset naming and mount properties don't match those from the HOWTO. I certainly agree that this is fragile. But it's an unofficial, experimental setup. That comes with the territory. Important progress is being made, and this will hopefully be more robust in the future. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to zfs-linux in Ubuntu. https://bugs.launchpad.net/bugs/1846424 Title: 19.10 ZFS Update failed on 2019-10-02 Status in zfs-linux package in Ubuntu: Invalid Bug description: On all my systems the update from zfs-initrams_0.8.1-1ubuntu12_amd64.deb failed the same is true for zfs-zed and zfsutils-linux.
