macOS and SMB share file size

[Machist]

Hello!

I installed Truenas in my old 2012 MacMini server (i7/16Gb/250GB SSD + 2Tb HDD).
I create SMB share and I can copy small files there ok, but large files +4GB cause problems.

I try to create CCC task (carbon copy cloner), but it says "CCC cannot reliably determine whether the underlying filesystem of the selected network volume supports files larger than 4GB."

Any ides what is wrong?

If I just clone/copy files directly (CCC) Data disk -> Backup disk it seems to work ok.
If I try to create new disk image I get that error "CCC cannot reliably determine whether the underlying filesystem....."

Might be that FS capabilities aren't being sent to the Mac correctly. It might also be that CCC has a bug in it. What version of TrueNAS is this and what is the output of `testparm -s`?

The testparm output is incomplete I believe (lacks majority of our default parameters).

Strange?? That is all what I get when I run 'testparm -s' in shell

Okay. Can you PM me a debug please (system->advanced->save debug).
