issues with macOS/Final Cut Pro (NFS/SMB)

[mikeboss]

first, a few remarks from my side (michael, systems integrator):

 

we're running release 6.6.6 and after reading the changelog of V 6.6.7 I decided to not upgrade for now.
while testing SMB, we tried with "Enhanced OS X interoperability" on and off.
the behavior with invisible files/folders in the Finder.app of macOS can be circumvented if we mount the NFS share using the terminal command "mount" with the option "nfc". using SMB, there are no problems with invisible folders.
we would prefer to use NFS instead of SMB (performance).
the issue with unpacking ZIP files cannot be reproduced on other NFS servers (for example Debian).

up until now I wasted countless hours to get this whole setup up and running reliably. I tried all imaginable combinations of options when mounting the NFS share with a terminal command (instead of using CMD-K on macOS to mount).

 

this is what the customer has to say:

 

We have setup an Xenon-based Unraid Server with 40TB of storage. The Shares are attached via NFS to an array of Macs and windows Pc's via Lan. The Unraid Version used is XXXX

We are using the Unraid for Photo- and Video Editing and Data storage using a multitude of Programs, mostly Apple Final Cut Pro X and Adobe Photoshop/Illustrator. Most Clients are Imacs and Macbook Pro's, some hooked up via Thunderbolt3 to 10GbE Adapters. 

The macs connect to the UnRaid via NFS with following settings: ??????

We do have some problems which we can reproduce on two different UnRaid Machines in different networks which rules out topology or Hardware as a problem:

Access via Finder: Zip files on the share cannot be unzipped (Error -1 )
Access via Finder: Folders sometimes show up as empty even though there are files inside.
Final Cut: When working on the Share in final cut in different Libraries they often close with an "cannot save changes" error. This is a big issue as we need to work from the machine. 
Illustrator: Saving as AI with Drawing Boards enabled renders an Unknown Error (!now) error. This only happens when trying via NFS

When accessing the Share via SMB an trying to open FCPX Libraries I get the error that SMB Shares are not supported, which they are since about two years, so something is not right there as well. However the other errors don't show up in this case.

We do think now that it must have something to do with the way NFS is implemented in UnRaid. Does anyone have a hint on where to start?

You are in an uncomfortable situation. The first thing I would try is changing to the next branch for releases, and install 6.7.0 rc7. Any solutions you find for 6.6.6 are likely to not apply to 6.7.x when it goes final, and 6.8.x is already in private alpha/beta.
