ZFS AnyRaid for Mixed Drives, 25.04.2 Is Out, and Viewer Questions | TrueNAS Tech Talk (T3) E036

On this week's TrueNAS Tech Talk, Kris and Chris dig into the pull request for the upcoming ZFS AnyRaid feature, which will allow mixed drive sizes to be used in a pool. Find out how "Tiles" will enable increased flexibility when building a pool, and whether or not it's the right fit for your requirements. TrueNAS 25.04.2 makes it out the door, bringing back Virtualization Classic, including Secure Boot for VMs and custom cloud-sync endpoints. Finally, viewer questions come in for admin account and space reporting challenges, as well as a long-awaited firmware flash to fix a noisy fan on a popular transcoding card.
