Comment 71 for bug 1872476

I just wanted to jump in here because this bug (I think) is causing me a lot of grief and I'd like to help if I can. I have Samba 2:4.11.6+dfsg-0ubuntu1.6 on Ubuntu 20.04. I've been using it fine for several months, serving files to Mac and another Linux (also 20.04). Just in the last few days I've found files not showing up at all on my Mac - I poked around quite a lot, going down what I guess was a rathole of thinking this was a Mac compatibility issue, but just today realised I am seeing something similar on my Linux client and have ended up here.

From a troubleshooting point of view I can see that this could be tricky to pin down as the behaviour I am seeing is so inconsistent. As it stands most of my files are accessible fine, but I am having trouble with a bunch of new files that I've just added (yes, I have checked permissions and ownership!). Sometimes the files are showing up as (empty) directories, other times not at all.

In a recent experiment I copied a folder full of files to a temp folder - they still showed up as directories in my clients - and then copied them back again. Now my Linux client is seeing them all as directories, but my Mac client is seeing half of the files (text files) not at all but the other half (videos) as a bizarre cross between a video file (which it should be) and a directory.
