    Phoronix: XFS Working Towards Online Repair, Many Underlying Improvements

    While XFS dates back to the 90's and has been in the Linux kernel for nearly two decades, this proven file-system continues aging gracefully and continuing to see more improvements. With Linux 5.7 is another step forward for XFS...

    XFS is a great filesystem. The feature I love more is project quotas (setting a size limit on a per-directory basis), coupled with lxc it makes it really easy to create virtual machines with dynamic limits

      So how far behind XFS is compared to ZFS, feature wise? Or the two are not really on the same category?

        Different categories, although XFS has experimental copy-on-write.

          That's why https://stratis-storage.github.io/ exists. It aims to provide ZFS features on top of XFS.

            One of the confusions that often come about is that ZFS (as originally designed) is not just a filesystem, but it is also a volume manager, and it is also a buffer pool manager, and it also has access to the hardware layer to perform certain functions to insure that what it is requesting is being done. ZFS was designed first and foremost to assure reliability (and availability and serviceability) on huge disk arrays. Performance can suffer due to that design priority compared to some filesystems which were targeted towards being more performant. ZoL has had to neuter some of the ZFS capabilities to fit within the Linux model, but ZFS still has some features that make the port useful.

              Although it is still in early development.

                Someone pointed XFS had more capabilities and features in IRIX which got lost when ported on Linux kernel like Guaranteed-rate I/O. Additionally, the fact that XFS had B-Tree functions pre-dating BTFS may explain why Red Hat switched to that file-system.

                  They should work towards it's partition shrinking as well

                    2.0.1 = early development. Okay.....
