One of the most interesting conversations at BSDCan wasn't about a new feature—it was about where FreeBSD could go next. For @allanjude.com, it was the conversations around FreeBSD jails and ongoing work to improve namespacing. Watch more: na3.hubs.ly/y0xGnP0 #FreeBSD #BSDCan

Modern media production isn’t one workload—it’s many. ZFS lets each dataset be tuned for its job: large renders, small database I/O, or mixed editorial files—all on the same pool. In a real NVMe environment: 55+ GiB/s reads, 35 GiB/s writes, up to 123% gains. 👉 Read: na3.hubs.ly/y0tj-_0

Made very few changes to the latest build and was thinking maybe I'll be able to ship this one without incrementing the shame version (last number in a version number) and 2 minutes into testing, it's already getting bumped.

A graphic showing "Pride Versioning" where the first number is the Proud Version. Then second is the Default Version. And the last number is the Shame Version.

Replicate VM datasets between Proxmox nodes using native ZFS tooling. zfs send -c pool/vmdata@snap | zfs receive backup/vmdata Compression reduces transfer time, while ZFS checksums ensure what arrives is exactly what you sent.

It would be automatic, but the L2ARC generally only catches a fraction of what is being evicted from the ARC. If your DDT is so large, a special vdev might be better (needs redundancy unlike L2ARC). With fast setup you can limit the size of the DDT to prevent it being so big in the first place

Allan Jude @allanjude.com · 20/06/2025

As you likely know, FreeBSD uses the "censoring" process to include 3rd party software. That means it contains a complete copy from upstream. Are you also going to complain about OpenSSL commits that are fixes for Linux? OpenSSH commits that only impact OpenBSD? It is part of tracking upstream.

Allan Jude @allanjude.com · 20/06/2025

Your view seems rather distorted. The relatime change didn't impact FreeBSD and zfsd is FreeBSD specific, so you can't blame OpenZFS. If you are having issues, I would recommend contacting KlaraSystems.com for FreeBSD specific ZFS support and big fixing

I don't know what you are talking about here. This has absolutely no impact on FreeBSD, there is no such thing as 'relative atime' on FreeBSD.
