The first release candidate of OpenZFS 2.4 is now available for testing of this ZFS file-system implementation for Linux and FreeBSD systems.
OpenZFS 2.4-rc1 adds compatibility for the latest Linux 6.16 stable kernel while continuing to support all the way back to Linux 4.18. OpenZFS 2.4-rc1 on FreeBSD continues supporting FreeBSD 13.3 and newer.
OpenZFS 2.4 is bringing better encryption performance by leveraging Advanced Vector Extensions 2 (AVX2) for AES-GCM, allow setting default user/group/project quotas, new deduplication optimizations, unified allocation throttling, and other enhancements.
Key Features in OpenZFS 2.4.0:
– Quotas: Allow setting default user/group/project quotas
– Uncached IO: Direct IO fallback to a light-weight uncached IO when unaligned
– Unified allocation throttling: A new algorithm designed to reduce vdev fragmentation
– Better encryption performance using AVX2 for AES-GCM
– Allow ZIL on special vdevs when available
– Extend special_small_blocks to land ZVOL writes on special vdevs (#14876), and allow non-power of two values
– Add zfs rewrite -P which preserves logical birth time when possible to minimize incremental stream size
– Add -a|–all option which scrubs, trims, or initializes all imported pools
– Add zpool scrub -S -E to scrub specific time ranges
– Release topology restrictions on special/dedup vdevs
– Multiple gang blocks improvements and fixes
– New dedup optimizations and fixes
