With these fixes in place, the TrueNAS 12.0 update train for Enterprise customers is being activated!

Known Issues

Key	Summary	Workaround
NAS-106992	Persistent L2ARC is disabled by default.	While the underlying issues have been fixed, this setting continues to be disabled by default for additional performance investigation. To manually reactivate persistent L2ARC, log in to the TrueNAS Web Interface, go to System > Tunables, and add a new tunable with these values: Type = sysctl Variable = vfs.zfs.l2arc.rebuild_enabled Value = 1
	TrueNAS "root" user account cannot be an SMB user.	This is an intentional change to improve software security and suitability for deployment in a variety of environments. Update the SMB configuration to use a different user account.
NAS-109078	TrueNAS Enterprise license summary may not list expansion shelves by name. This does not affect enclosure management or expansion shelf functionality.
