Supported Platforms

  • Linux: compatible with 3.10 - 6.5 kernels
  • FreeBSD: compatible with releases starting from 12.2-RELEASE

New Features

  • Block cloning (#13392) - Block cloning is a facility that allows a file (or parts of a file) to be "cloned", that is, a shallow copy made where the existing data blocks are referenced rather than copied. Later modifications to the data will cause a copy of the data block to be taken and that copy modified. This facility is used to implement "reflinks" or "file-level copy-on-write". Many common file copying programs, including newer versions of /bin/cp on Linux, will try to create clones automatically.

  • Linux container support (#12209, #14070, #14097, #12263) - Added support for Linux-specific container interfaces such as renameat(2), support for overlayfs, idmapped mounts in a user namespace, and namespace delegation support for containers.

  • Scrub error log (#12812, #12355) - zpool status will report all filesystems, snapshots, and clones affected by a shared corrupt block. zpool scrub -e can be used to scrub only the known damaged blocks in the error log to perform a fast, targeted repair when possible.

  • BLAKE3 checksums (#12918) - BLAKE3 is a modern cryptographic hash algorithm focused on high performance. It is much faster than sha256, sha512, and can be up 3x faster than Edon-R. BLAKE3 is the recommended secure checksum.

  • Corrective "zfs receive" (#9372) - A new type of zfs receive which can be used to heal corrupted data in filesystems, snapshots, and clones when a replica of the data already exists in the form of a backup send stream.

  • Vdev properties (#11711) - Provides observability of individual vdevs in a programmatic way.

  • Vdev and zpool user properties (#11680) - Lets you set custom user properties on vdevs and zpools, similar to the existing zfs dataset user properties.

Performance

  • Fully adaptive ARC (#14359) - A unified ARC which relaxes the artificial limits imposed by both the MRU/MFU distribution and data/metadata distinction. This allows the ARC to better adjust to highly dynamic workloads and minimizes the need for manual workload-dependent tuning.

  • SHA2 checksums (#13741) - Optimized SHA2 checksum implementation to use hardware acceleration when available.

  • Edon-R checksums (#13618) - Reworked the Edon-R variants and optimized the code to make several minor speed ups.

  • ZSTD early abort (#13244) - When using the zstd compression algorithm, data that can not be compressed is detected quickly, avoiding wasted work.

  • Prefetch improvements (#14603, #14516, #14402, #14243, #13452) - Extensive I/O prefetching analysis and optimization.

  • General optimization (#14121, #14123, #14039, #13680, #13613, #13606, #13576, #13553, #12789, #14925, #14948) - Numerous performance improvements throughout.

  • Module options - The default values for the module options were selected to yield good performance for the majority of workloads and configurations. They should not need to be tuned for most systems but are available for performance analysis and tuning. See the module parameters documentation for the complete list of the options and what they control.
