    Phoronix: Red Hat's Stratis Storage Project Reaches Its 1.0 Stable Milestone

    Stratis has been the Red Hat play two years in development for delivering next-gen Linux storage following their decision to abandon Btrfs support. Stratis offers ZFS and Btrfs like functionality and a lot of other new capabilities while this past week marked its first stable release...

    TLDR EL8 won't have any filesystem with transparent compression, let alone dedup. We're back in the 2000s again, for a good 3-5 years.

    GG, Red Hat, GG.

        It'll be interesting to see how Stratis will shake out. I'm currently all-in on the ZFS-on-Linux ecosystem, but maybe someone will finally dethrone ZFS as the top dog.

          Stratis basically offer snapshotting, by leveraging the block-level snapshotting of LVM.

          Stratis misses about absolutely every other feature of BTRFS/ZFS and co :
          - the most critical one : NO CHECKSUMs. Yup, this makes Stratis perform a tiny bit faster, but it doesn't enable detecting bit rot.
          - almost as important : Stratis isn't fully copy-on-write, it's limited by the FS sitting on top of the LVM layer (currently ext4). This removes some safeties (that ext compensates by using a journal since ext3) and make it slightly less flash-friendly (though still much better than FAT-based filesystems).
          - no compression (currently not supported by ext4)
          - no deduplication (though this could be developed at a coarse block-level inside the LVM snapshotting layer).
          - no send/receive (LVM has no idea of what its blocks are used for. Though something could be ducktaped by using snapshot and thin volumes).
          etc.

            in my experience BTRFS is mostly there (give or take a few features that needs fine tuning, mostly RAID5/6 not being production ready, but progressively getting there over the latest patches), basically it's a nearly-top dog.

            BCacheFS would eventually have a good chance the above two top dogs. (but still hasn't finished implementing most of the key features), and has been started with the explicit goal of achieving this. It's basically a nice puppy running a bit behind.

            Stratis really looks as a duck-taped stop-gag measure to quickly come-up with a snapshotting solution. Not a valid contender in my opinion. It's basically a gerbill with angry brows painted on it.

              So......... no one is concerned that they developed it for 2 years, and never had it available for testing on Fedora or any other distro until their 1.0 release? And now they want yo ram it down Linux users throats after getting ZERO input on its design outside of Red Hat?

                What happened to release early, release often? What happened to the community's direction and input mattering? What happened Red Hat?

                  Since I moved to zfs I don't look back. So much better than btrfs.

                    I think they made a big mistake with it. I don't have an use case for such filesystem, because I just use rhel/centos on vps and for development, but I wouldn't used this stratis because of lack of wider testing.
                    I think noone is reading anything anymore before commenting. For one, this is not a filesystem at all. Stratis is a userspace manager that reuses many of widely used components like xfs and devicemapper. More details at
