  • ZFS On Linux Runs Into A Snag With Linux 5.0

    While the Linux 5.0 kernel has a lot of enticing features and improvements, if you rely upon ZFS On Linux (ZOL) you will probably want to hold off on trying the Linux 5.0 release candidates at this time.

    ZFS On Linux currently fails to build against the Linux 5.0 kernel sources. This isn't due to a trivial API change but rather the 5.0 kernel is no longer exporting the __kernel_fpu_begin and __kernel_fpu_end symbols, which the ZOL kernel module relies upon as part of the file-system's checksums.

    There isn't a simple solution for this immediately, especially one that doesn't involve using GPL symbols, due to license compatibility issues with the out-of-tree ZOL kernel code. But surely with time and new code a solution can come about as it doesn't look like the upstream kernel developers are interested in any maneuvering to help out ZOL specifically (or rarely out-of-tree modules for that matter).

  • [Older] The future of ZFS in FreeBSD

    The sources for FreeBSD's ZFS support are currently taken directly from Illumos with local ifdefs to support the peculiarities of FreeBSD where the Solaris Portability Layer (SPL) shims fall short. FreeBSD has regularly pulled changes from Illumos and tried to push back any bug fixes and new features done in the context of FreeBSD. In the past few years the vast majority of new development in ZFS has taken place in DelphixOS and zfsonlinux (ZoL). Earlier this year Delphix announced that they will be moving to ZoL
