BSDCan 2026 is in the books, but there's still plenty to discuss. Join @allanjude.com, Kyle Evans, and Colin Percival next week for a live AMA covering conference highlights, FreeBSD developments, and audience Q&A. Register here: na3.hubs.ly/y0vP1c0 #BSDCan #FreeBSD #OpenSource

What if your ZFS vdevs didn't require matching drive sizes? At BSDCan 2026, @allanjude.com will break down AnyRAID—a new ZFS vdev type that unlocks more usable capacity, mixed-drive flexibility, and easier expansion over time. 👉 www.bsdcan.org/2026/timetab... #BSDCan #FreeBSD

With the return of Bruce A-3 to service, Ontario has broken 10,000 MW of generation from Nuclear for what I believe is the first time in some years. It won't last too long, as Bruce B-5 will enter is refurbishment cycle later this year, with units 7 and 8 to follow. live.gridwatch.ca

We're starting soon! Join @allanjude.com and @lawrencesystems.com for a practical session on tuning ZFS for database performance. Latency, IOPS, bottlenecks, caching, compression, and safe production tuning for PostgreSQL, MySQL, and Oracle. 👉 Join the party: na3.hubs.ly/y0sW3-0

What happens when database workloads meet NVMe storage on ZFS? Join @lawrencesystems.com & @allanjude.com for a webinar on tuning ZFS for latency and IOPS across PostgreSQL, MySQL, and Oracle. Save your spot: na3.hubs.ly/y0sW6J0

Tuning ZFS for databases shouldn’t feel like guesswork. Next week @allanjude.com & @lawrencesystems.com break down safe ways to improve latency + IOPS. Real bottlenecks. Real metrics. No risky changes. 👉 Register: na3.hubs.ly/y0sW6J0

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.

Technical independence starts with infrastructure. Open technologies like FreeBSD and OpenZFS give organizations transparency, control, and the ability to build storage systems without vendor lock-in. 🔗: na3.hubs.ly/y0ppZy0

Enable fast, transparent compression with: zfs set compression=lz4 pool/fs lz4 reduces storage footprint with virtually no performance penalty — often improving throughput while saving space. One simple command. Immediate efficiency gains. #ZFS #OpenZFS #Klarasystems

Teams are rethinking where their critical systems live. OpenZFS stands out in production—open source, proven at scale, no licensing traps—but expert support matters. Save up to 35% on Klara’s OpenZFS support through Feb 17, 2026. Get tuning and long-term support: na3.hubs.ly/y0hn9K0

WOW !! A research team at the University of Utah discovered a version of the original #UNIX operating system from 1973. www.youtube.com/watch?v=IR-f...

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.

RAID is not a backup, it protects availability and uptime, not your data. Pair RAID with a full disaster recovery plan to ensure both the availability and resiliency of your data. Good backups start with one simple question: What are you protecting your data from?

With ZFS, encryption happens at the dataset level—so you can manage, scrub, or repair your pool without unlocking all your data. Smarter, safer workflows. Partner with Klara: bit.ly/4dSNhtJ

We've been telling people for decades that ZFS Dedup isn't good. Now we've fixed it, Fast Dedup makes many workloads able to take advantage of this core ZFS feature. Come learn more about deploying Fast Dedup for modern workloads.

In our latest webinar, we shared how Klara enhanced a customers FreeBSD-based system by limiting debugger access, protecting sensitive memory, like VPN keys, without losing the ability to debug in production. Next up: Fast Dedup with ZFS >> bit.ly/4mM9r4H

Sorry, I accidentally some words here. I found an integer overflow in a terminal emulator written in Rust.

chat is this for real? 🫣 sadly it is www.reddit.com/r/ableton/co... i hope you learned lessons and not trusting it blindly

"In defense of my loud keyboard"

ZFS just got smarter at spreading writes across your disks. The new Unified Allocation Throttling (PR17020) fixes major flaws in how space was balanced across vdevs—meaning less fragmentation, better performance, and more efficient use of your storage. Big news if you’re running ZFS at scale!

You underestimate the importance of such meetings. It might give you valuable pointers for your career in software development. Khaha

I always think of this when someone says they do everything with AI now
