    So... have Oracle said this is ok yet, or are they still firing any employee who discusses the possibility of ZFS on Linux in public?

      Umm, why you ask? Omnomnomnomnomracle is a strong supporter of btrfs so they will never allow their older stuff to compete with it.

        Looking at both https://btrfs.wiki.kernel.org/index.php/Gotchas#Issues and https://github.com/zfsonlinux/zfs/issues

        hell will freeze over before either becomes fully enterprise-ready.
        Latter seems to have amount of "Issues" doubled since I last checked it ^^

          You'll need more solid evidence than just counting number of issues on some list before making such strong statements.

          FreeNAS is deployed in production in many places, so is ZFS-on-linux. And it runs great. As good as it gets.

          For the btrfs part, I invite you to read Omnomnomnomnomnomracle's updates to their "unbreakable Linux" (aka RHEL clone) about it http://www.oracle.com/technetwork/se...w-2043074.html
          Continued improvements in scalability, performance and stability for Btrfs are key features of this latest release. Btrfs now includes RAID 5 and RAID 6 support.


          Btrfs now includes RAID 5 and RAID 6 support.

          Btrfs RAID 5 and RAID 6



          So be afraid, be very very very afraid of what they are doing.

            Yeah for ZFS it's probably better to stay off Linux and stick with FreeBSD, etc.

              FreeNAS ain't using ZFS-on-linux. It's not based on Linux.

              Yes, I am aware of Raid5/6. It wasn't the only listed item though.

                Look up "OpenZFS project". ZFS-on-Linux is their Linux downstream, FreeBSD is using their BSD port. There is also a Mac port. Illumos (open solaris fork) was the "upstream" until the OpenZFS project was created.

                Seriously, ZFS far too big to afford to go each their own way.

                Unless you seriously think most bugs come from some sugarcoat code to interface a mostly self-contained module with Linux kernel (not kidding, to have ZFS encryption support they integrated the whole damn crypto subsystem of Illumos kernel in the ZFS driver module), you need to filter the amount of bugs from the upstream project, or not bugs at all ("issues" in Github aren't necessarily a bug, might be anything, even spam or clueless users), so have fun doing that with your links above.

                Yes, I am aware of Raid5/6. It wasn't the only listed item though.
                My point was that Omnomnomnomnomracle is pushing a not-yet-100% stable feature on production systems anyway, so the "enterprise-ready" term is somewhat meaningless.

                  Yes I know. But also OpenZFS has been "native" to FreeBSD and it's derivates close to a decade - work that's still is being done on ZoL was completed long a go. At least ~1y a go, you could successfully import ZFS pool from Linux into FreeBSD machine but could run into troubles doing the reverse - because pools were not quite 'feature-equal'.

                  ZFS in itself is a major chunk of monolithic code that wants to do and handle a lot. Linus would not accept such a chunk of "foreign" code into mainline, so big part of the ZoL effort has been trying to create and use piecemeal native code. Which slows the implementation down to a crawl.

                  Illumos encryption is something which perfectly illustrates what I told above.

                  Oracle Linux also has XFS. How it's "pushing" Btrfs?

                    They also have FAT32 for that matter.

                    By including btrfs in their "unbreakable Linux" offering, and by declaring btrfs RAID 5 and 6 are usable after their update to kernel 4.12 or something.

                    They also describe it as if it was already production-ready in their page http://www.oracle.com/technetwork/se...w-1898045.html

                    SUSE didn't go anywhere near declaring RAID5/6 usable.
