Tell HN: Ubuntu 21.10 is currently broken when using ZFS
I just wasted a few hours upgrading to Ubuntu 21.10 and experiencing filesystem corruption on my ZFS filesystem.
I also experienced filesystem corruption after a fresh installation of Ubuntu 21.10 with ZFS.
It turns out there is a known issue with ZFS on Ubuntu 21.10 mentioned in the long release notes. I thought I would draw attention to it to save other people time and prevent losing data.

- Flimm 5y agoHere are the release notes for Ubuntu 21.10: https://discourse.ubuntu.com/t/impish-indri-release-notes/21951 https://discourse.ubuntu.com/t/impish-indri-release-notes/21... Search for "ZFS". You'll find this part under "Known Issues": > The version of the ZFS driver included in the 5.13.0-19 kernel contains a bug that can result in filesystem corruption. Users of ZFS are advised to wait until the first Stable Release Update of the kernel in 21.10 before upgrading.
