Notable Changes
- To prevent excessive resource usage, especially on systems with large HDD storage pools, SMART test results no longer appear directly on the Storage dashboard. Click View S.M.A.R.T. Tests on the Disk Health widget to open the S.M.A.R.T. Test Results of POOL screen.
- Allow configuration of IO bus for disk devices in Instances (NAS-134250). This enables users to create virtualized disks using a standard other than VirtIO in cases where the OS image does not by default include VirtIO drivers.
- To improve stability and prevent unsupported SMB configurations from breaking on migration from TrueNAS CORE, TrueNAS automatically removes the SMB auxiliary parameters
wide links
,use sendfile
,vfs objects
, andallow insecure
during migration (NAS-132911). - To prevent unexpected failures in SMB shares, TrueNAS automatically disables SMB2/3 lease support globally when multiprotocol SMB/NFS shares are enabled (NAS-133680).
- Reserve 2 GiB of disk space (but no more than 1%) to allow the data disk to be replaced with a slightly smaller one in the future (NAS-134309).
- Bugfix: Ensure disk temperature reporting is available for all disks (NAS-130766).
- Bugfix: Allow SMB authentication for usernames with a capital letter (NAS-134346).
- Bugfix: Fix top toolbar icon colors for the iX Blue, Paper, and High Contrast UI themes (NAS-133853).
- Bugfix: Enable the applications Web UI button when accessing from IPv6 or mDNS name (NAS-133655).
Note
Instances (Incus-powered containers and virtual machines) are an experimental feature intended for community testing only. Functionality may change significantly between releases, and instances may not upgrade reliably. Use this feature for testing purposes only—do not rely on it for production workloads. Long-term stability is planned for future TrueNAS Community Edition releases.
