On today’s episode of TrueNAS Tech Talk, new versions abound - 25.04.2 is next week, and 25.10 is code-freezing soon, so Kris and Chris are ready to talk about some of the performance tuning that’s been happening under the hood of ZFS to push performance on high-end systems. Kris is heading to the OpenZFS Developer Summit in October; it’s a great place to get involved with the real nuts and bolts of ZFS, and they talk about how everyone can help contribute to the world of open source software. There’s some clarifications on Linux Containers (LXC) in 25.10, and some community troubleshooting going on for pools that won’t import - learn where you can start probing the detailed ZFS debug logs to see what’s going on behind the progress bar.
It is great to be kept in the loop about how TrueNAS is moving forwards and feedback from the Devs about various issues. The conference on OpenZFS is definitely above my pay grade, but I am sure those going will enjoy it.
Good episode. I’m excited to see 25.04.2 come out next week. And thanks for taking my question. I have see the Metadata issue come up more frequently and I can see it could be due to TrueNAS popularity and/or systems which might not be the best hardware to run a TrueNAS system on. And please @HoneyBadger don’t set any drives on fire, but if you do, post a video
I’d love to see a case of is_computer_on_fire() returning a non-zero result…
Unfortunately, ZFS was never ported to the OS which had this “interesting” kernel function.
Kris has a 4K camera, I’m still on 1080p - but yeah, it does seem like the autofocus or something had a moment and failed. Looking at the raw files it seems like my bitrate took a dive relative to previous episodes so perhaps they’ve changed a setting behind the scenes that I need to look at.
