I haven’t made any such changes. I merely upgraded the OS. Please consider the possibility that EE made some changes on its own, just as Dragonfish was not happy with SMB Aux parameters that CORE happily ignored.
The SMB options for the dataset feature both the AFP Legacy check box and the Apple Character compatibility checkboxes (both unset).
I cannot remember if this dataset at one point was served via AFP or not. Is there a way to determine this?
Also, Apple-Character compatibility cannot be checked/unchecked. Is there a way to change that behavior by TrueNAS? I tried turning off SMB, disabling the SMB Share, etc. all to no avail. Neither TrueNAS 24.04.2 nor 24.10RC1 will allow me to enable Apple-style Character encoding.
