    ZFS is the FS for Containers in Ubuntu 16.04 and how it compares to btrfs

    20th February 2016

    Recently in hacker news the following was posted: ZFS is the FS for Containers in Ubuntu 16.04.

    I must admit the 16.04 demo does look very pleasant to work with.

    However, bringing in ZFS into Linux reminded me of a fairly recent comparison of ZFS and btrfs that I had to do when building my home NAS.
    At that time, few months ago, I’ve arrived (among others) at the following conclusions:

    • ZFS on FreeBSD is reliable, though a memory hog;
    • on Debian, OpenVault seems to be a good NAS web-management interface;
    • on FreeBSD, FreeNAS is good (there is also Nas4Free fork of an older version, but I haven’t looked into it deep enough);
    • running ZFS on linux (even as a kernel module) is the least efficient solution, at least partially because kernel’s file caching and ZFS’s ARC cache are two separate entities;
    • although btrfs offers features very similar to ZFS, as of few months ago OpenVault did not offer btrfs volumes support from the web-interface.

    In the end, I’ve decided to go with FreeNAS, and it seems to work well so far.

    But had anything changed in the btrfs vs ZFS on Linux field?
