TrueNAS 12.0-U1-1

iXsystems is pleased to announce the general availability of TrueNAS 12.0-U1.1! This is a minor version release to work around a critical ZFS issue that could impact systems with a rare but serious issue with data integrity under some very uncommon access patterns. To date iXsystems has only observed these issues while running with some very specific virtualization workloads, however ALL TrueNAS 12.0 or higher users are encouraged to upgrade their systems immediately to 12.0-U1.1 out of an overabundance of caution.

TrueNAS Enterprise customers with 12.0 installed can always contact iXsystems Support for assistance upgrading their TrueNAS deployments.

TrueNAS 12.0-U1.1 Changelog

• NAS-108627 : While the underlying ZFS issue causing the instability is being resolved, there has been a temporary reversion of the ZFS CFA patch. This means that Asynchronous Copy-on-Write is temporarily disabled in TrueNAS 12.0-U1.1, with the goal to re-enable this functionality in a later TrueNAS 12.0 update release after this issue has been fully resolved.
