    Phoronix: ZFS On Linux 0.8.1 Brings Many Fixes, Linux 5.2 Compatibility Bits

    Released at the end of May was the huge ZFS On Linux 0.8 release with many new features like native encryption, TRIM/discard support for SSDs, device removal, Python 3 compatibility with its tooling, pool check-points, and much more. Out today is now the first maintenance release following that big release...

    I hope Oracle sends them a cease and desist letter. This project isn't even a waste of time, it's just harmful.

      Well, I think it is pretty cool even though I am just starting to get into using it, right now just in a virtual image with virtual disk images. Basically to learn. Do we have anything better on Linux yet that covers RAID and all the rest, all together, not just a bunch of layered stuff? Seriously, do we?

          It is weird, how many times will this out of tree drive face situations like this?

            LVM exists.

              Layered is closer to the unix philosophy of small sharp tools but I guess we have not been letting that stand in the way of progress with Linux, Systemd, etc. I'd like ZFS in the kernel, but for now we have layers(lvm/crypt/integrity/fs) or the feature lacking buggy btrfs.

                You don't.

                ZFS doesn't compete with MD, LVM and ext4/xfs.. it competes with NetApp and EMC.

                Big big data.. pretty sure Twitter is on ZFS. (Edit: It was, not any longer? Tho there are other large customers and products)

                https://www.datto.com
                https://www.joyent.com
                https://nexenta.com
                https://www.ddn.com
                And of course.. https://www.ixsystems.com/truenas

                I think some company with an O has a product too.. idk I avoid them on principle.. And their version sucks anyhow.

                  Layered isn't the right choice in a FS. A FS should be stable and not subject to breakage thanks to moving parts. FSes as they are now are to brittle to handle the cases were an upgrade goes wrong. And our best protection against that case is still duplicating data.

                  Compare that to utilities that can be piped together. If one version of ls is giving you problems, it doesn't destroy your data, the OS or anything else. (Yes it could if a really buggy version existed, but you get what I mean.

                    Stop you have a mistake.

                    MD, LVM and ext4/xfs are used in solutions that are used as alternatives to NetAPP and ZFS like https://stratis-storage.github.io/faq/. Please note I did not type EMC.
                    https://germany.emc.com/collateral/w...tdi-vnx-wp.pdf
                    EMC in fact backs using xfs in a lot of their configurations. EMC provides the block device and volume management side integration into LVM.


                    So if ZFS competes with EMC it has to compete in part with the xfs file system because the xfs file system is part of EMC solutions.
