Okay, after hours of SMB share thrashing with my Python script across macOS, Windows 11, and Synology, I’ve finally landed on a configuration that seems to workaround the issue. I’d love for others to give these settings a try too.
Here is the nsmb.conf file that I’m using on my Mac (located at /etc/nsmb.conf): macOS SMB Configuration to Prevent Directory Caching Issues · GitHub
I suspect (but haven’t confirmed) that the two settings that workaround this issue are dir_cache_off=yes and mc_on=no. I hope this works!
