Phoronix reports that OpenZFS has recently added a new feature called RAIDZ expansion. This feature allows for the incremental addition of disks to a RAID-Z group, enabling users to expand the capacity of their RAID arrays one disk at a time. This feature is particularly useful for small pools.

The development of RAIDZ expansion has been in progress for several years, with the FreeBSD Foundation sponsoring the initial work in 2017. iXsystems and vStack have also provided sponsorship to complete this feature.

Netgate has announced the Release Candidate (RC) of pfSense CE software version 2.7.1. This open-source project, supported by Netgate since 2008, is a widely-used firewall and routing platform. The RC release is an opportunity for users to try out the new version and provide feedback.

The major changes and features in pfSense CE software version 2.7.1 include:

1. Upgraded OpenSSL to version 3.0.12: This upgrade was necessary as OpenSSL 1.1.1 has reached its End of Life and will no longer receive security patches. The upgrade removes older and weaker encryption and hash algorithms, improving security.

2. Kea DHCP added as an opt-in feature: The Kea DHCP server is now available as an optional feature. While it is not feature complete in this version, users can switch to Kea DHCP by navigating to the System > Advanced menu and changing the DHCP Options to “Kea DHCP”. However, switching to Kea DHCP may result in the ignoring of assigned hostnames and dynamic lease registration in DNS.

3. Improved support for SCTP: Support for SCTP in firewall rules, NAT, and logging has been enhanced. Users can now filter SCTP packets by port number, in addition to source and destination address.

4. IPv6 Router Configuration moved: The IPv6 Router Advertisement configuration has been relocated to Services > Router Advertisement as part of the integration with the Kea DHCP server.

Other changes in this release include upgrading PHP to version 8.2.11, upgrading the base operating system to a more recent point of FreeBSD 14-CURRENT, and addressing various bugs and issues.

Testing of the RC software release is crucial to ensure its reliability and robustness for all users. Netgate encourages users to download and test the release candidate, and provide feedback on any issues they encounter.

To install the upgrade, users can follow the detailed Upgrade Guide available in the pfSense documentation. It is recommended to back up the pfSense CE configuration prior to the upgrade. The upgrade can be performed through the web interface by navigating to System > Update and setting the Branch to “Next Stable Version (2.7.1-RC)”.

OpenZFS, the popular file system for Linux servers and home labs, has received a significant performance enhancement. The new feature improves write performance scalability by allowing parallel syncing of multiple datasets/objects and reducing locking contention.

This optimization was developed by Brian Behlendorf from the Lawrence Livermore National Laboratory (LLNL) over the summer. Tests conducted on an AMD EPYC server running OpenZFS showed a remarkable improvement in write bandwidth. The write performance increased from 1328MB/s to 2495MB/s, as reported by the developer. Another developer also observed a significant boost in FIO write bandwidth, jumping from 1386MB/s to 2449MB/s.

In addition to the substantial increase in write performance, the new feature also reduces locking contention. This improvement further enhances the overall efficiency of OpenZFS.

The ZFS sync parallelism for OpenZFS has been merged into the Git repository, as announced in the recent pull request. Detailed information about this enhancement can be found in the pull request link provided.

This update is a significant milestone for OpenZFS users, as it greatly enhances write performance scalability and improves the overall efficiency of the file system. The optimization is expected to benefit users in various scenarios, from Linux servers to home labs and DevOps environments.
