Is ZFS on Ubuntu 18.04 root supported?












1















I'm using Ubuntu 18.04 with a root filesystem on ZFS without any problems but have discovered this page from the Ubuntu Wiki which states ZFS on root is not supported: https://wiki.ubuntu.com/Kernel/Reference/ZFS




ZFS support was added to Ubuntu Wily 15.10 as a technology preview and comes fully supported in Ubuntu Xenial 16.04. Note that ZFS is only supported on 64 bit architectures. Also note that ZFS is only supported for data storage, not the root filesystem.




Can anyone tell me if this is still relevant in Ubuntu 18.04? For example if I raised a paid for support request with Canonical would they be willing to help?
This blog post from Ubuntu suggests it's a valid configuration: https://blog.ubuntu.com/2018/10/15/deploying-ubuntu-root-on-zfs-with-maas

          It's not supported by Canonical. The Ubuntu Wiki page on ZFS says:




          In addition to be able to have ZFS on root, install:



          sudo apt install zfs-initramfs



          The zfs-initramfs package is in universe (for 16.04, 18.04 and 18.10), which means that it's maintained and supported by the community, not Canonical. If it ever gets promoted to main, where zfsutils-linux is, then we can assume support.
