ZFS 2.4 introduced zfs rewrite, a clean way to reapply dataset settings to existing data. Rewrite a file or directory in place, and ZFS treats it like the data was rewritten with itself. Perfect for applying new compression settings without moving data around. Watch here: na3.hubs.ly/y0xXd80
Hardware RAID was built for a different era. Learn how ZFS protects data with end-to-end checksums, self-healing capabilities, copy-on-write, and filesystem-aware rebuilds that reduce risk and improve reliability. Read more: na3.hubs.ly/y0xXg-0 #OpenZFS #Storage #SysAdmin
Managing multiple FreeBSD jails? Skip the SSH session. Run commands directly inside a jail from the host with jexec—ideal for Ansible playbooks, cron jobs, and day-to-day administration. #FreeBSD #OpenSource #SysAdmin
In our upcoming webinar, Allan Jude and Gordon Tetlow of the FreeBSD Security Team discuss FreeBSD's security architecture and the processes behind investigating vulnerabilities. Save your spot: klarasystems.com/webinars/fre... #FreeBSD #OpenSource
Use this FreeBSD built-in tool for downloading files instead of installing curl or wget. You can use fetch to retrieve files over HTTP or HTTPS, making it a simple choice for scripts, automation, and systems where you want to avoid unnecessary dependencies. #FreeBSD #KlaraSystems #OpenSource
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
FreeBSD After Hours AMA: Post-BSDCan Recap - Klara Systems
Join Klara for the BSDCan 2026 FreeBSD AMA and hear the biggest BSDCan takeaways, FreeBSD updates, OpenZFS discussions, and production-focused insights from Allan Jude and Kyle Evans.

If your monthly ZFS scrub slows production, the scrub isn't the problem—your pool design is. Learn why ZFS scrub performance reveals storage bottlenecks and how special VDEVs can reduce maintenance impact while improving resiliency. Read more: na3.hubs.ly/y0ypQ00
If Scrubs Hurt, Your ZFS Design Is Broken - Klara Systems
ZFS scrubs performance issues often point to storage design problems—not the scrub itself. Learn how pool design, and special VDEVs improve performance.

“How should I set up my pool with what I have?” “What drives should I buy?” It’s not about disks—it’s about VDEV design. We break down mirrors, RAIDz1/2/3, dRAID, LOG, CACHE (L2ARC), SPECIAL, and SPARE, and the tradeoffs behind each. 👉 na3.hubs.ly/y0xX8N0
OpenZFS - Understanding ZFS vdev Types - Klara Systems
Understand ZFS vdev types and how they impact performance, redundancy, and storage efficiency to optimize your OpenZFS setup.

Are your FreeBSD packages up to date? Run sudo pkg audit -F to update the vulnerability database and check installed software for known security vulnerabilities and CVEs. Regular audits help catch vulnerable packages early.
How does AnyRAID allocate data? It supports mirrors of any depth plus RAIDZ1, RAIDZ2, and RAIDZ3, intelligently placing data on disks with the most free space while keeping future expansion in mind. Watch the recording: na3.hubs.ly/y0y6Dy0 #OpenZFS #AnyRAID
Don’t skip this one if you use Dedup. "zpool prefetch -t ddt tank" This preloads the deduplication table into ARC after reboot, reducing cold-start latency and improving early workload consistency. Without it, dedup starts cold after reboot. #OpenZFS #Klarasystems #dedup

Data corruption isn't always obvious. ZFS scrubs verify every allocated block in a pool, using checksums and redundancy to detect and repair issues before they become data loss. Learn more: na3.hubs.ly/y0w-8-0 #OpenZFS #ZFS
Understanding ZFS Scrubs and Data Integrity - Klara Systems
Learn how ZFS scrubs protect data integrity by verifying checksums, and monitoring pool health with zpool status.

Thanks to everyone who joined our FreeBSD AMA webinar! Our speakers highlighted the biggest changes in FreeBSD, some of their favorite sessions, and what's to come for FreeBSD. If you missed the live event, be sure to tune into the recording! na3.hubs.ly/y0x1d00
FreeBSD 15.0 introduces native inotify support, making it easier to monitor filesystem events with Linux-compatible tools. Use: inotifywait -m ~/uploads -e close_write to watch for completed file writes and trigger automated workflows, file processing pipelines, or notifications. #FreeBSD
Happy Fourth of July weekend! 🇺🇸 Wishing our customers, partners, and the open-source community across the United States a safe and enjoyable Independence Day. Thank you for trusting Klara to help build reliable, resilient infrastructure all year long. #FourthOfJuly #OpenSource #OpenZFS #FreeBSD
"Supply chain delays and rising drive costs don't have to limit your storage options." Watch our Understanding ZFS AnyRAID webinar to learn how AnyRAID makes better use of mixed-capacity drives, plus the architecture, use cases, and tradeoffs behind it. ⬇️ na3.hubs.ly/y0x1c-0 #OpenZFS #Hexos
🍁 Happy Canada Day! We're proud to call Canada home while supporting OpenZFS, FreeBSD, and open-source infrastructure worldwide. Thank you to our customers, partners, and community. Wishing everyone a safe and happy Canada Day! #CanadaDay #OpenSource #FreeBSD #OpenZFS
1 hour to go. Join Allan Jude, Kyle Evans, and Colin Percival for a live FreeBSD AMA discussing BSDCan highlights, production infrastructure, upcoming FreeBSD developments, and audience Q&A. Register here: na3.hubs.ly/y0wSCP0 #FreeBSD #BSDCan #OpenSource
Thanks to everyone who joined our AnyRAID webinar! @allanjude.com & Jon Panozzo explored how AnyRAID helps maximize usable capacity with mixed-size drives, supports expansion and contraction, and the tradeoffs to consider before deployment. Watch the recording: na3.hubs.ly/y0wSB00
Colin Percival is coming back to Klara as a guest speaker! He’ll discuss his takeaways from BSDCan 2026, answer audience questions and explore what the latest FreeBSD developments could mean for production environments. Miss out on BSDCan? Join our FreeBSD AMA webinar: na3.hubs.ly/y0vP090
