Known Issues

Key	Summary	Workaround
NAS-109842	2FA authentication missing for enterprise	Use the following CLI instructions for the workaround: Add Secret Key to authenticator: `midclt call auth.twofactor.config {"id": 1, "otp_digits": 6, "secret": "3FVIQJ6ESUVRLRXR", "window": 0, "interval": 30,"services": \{"ssh": false}, "enabled": false}` Enable 2FA Service: `midclt call auth.twofactor.update '{"enabled": true}'`
NAS-110785	Inherit option overriding encryption on dataset creation	When creating the dataset uncheck inherit encyryption first, then uncheck encryption before saving. If you uncheck encryption first it will prevent inherit encryption from being displayed and inherit encryption will silently remain enabled.
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.
