The ZFS on Linux project has been renamed OpenZFS. Behlendorf also stated that Linux and FreeBSD are now supported from the same repository. It means all of the OpenZFS features are available on both platforms. OpenZFS 2.0.0 release is available on FreeBSD. It can be installed on FreeBSD 12 and it will also be the base FreeBSD version in FreeBSD 13.
- Sequential resilver: The sequential resilver feature can rebuild a failed mirror vdev in a fraction of the time it would take a traditional healing resilver. Full redundancy is restored as quickly as possible and then the pool is automatically scrubbed to verify all of the data checksums.
- Persistent L2ARC: This feature makes the L2ARC cache device persistent across reboots thereby eliminating the usual cache warmup time normally needed after importing your pool.
- ZStandard compression: ZStandard is a modern, high performance, general compression algorithm which provides similar or better compression levels to GZIP, but with much better performance. ZStandard provides a large selection of compression levels to allow a storage administrator to select the preferred performance/compression trade-off.
- Redacted zfs send/receive: Redacted streams allow users to send subsets of their data to a target system. This allows users to save space by not replicating unimportant data within a given dataset or to selectively exclude sensitive information.
