Thank you for your post which fixed the issue it hit me tonight.
At this occasion I'd like to ask the community if someone could explain why these surprises happen quite often.
A new update brings nasty errors such as this. Today we have Ascension of Jesus so we have free time. We watched TV last night and 2 am I told my family "let me quickly update our two FreeNA, will be to bed in 10 Minutes". Well it took me almost an hour to fix the problem.
I understand are nightly builds are dangerous. But from a "official" update I expect to have those who present it a major service such as SMB to be tested and not to fail. Unless they do not use SMB and in such case I wonder what else they don't test what is included hence leaving me and many others be the guinea pig.
