So since switching back to using Windows with DrivePool on my fileserver again a few weeks ago. We have been running into issues with MacOS clients accessing fileshares on it.  Browsing and especially creating folders/files, where they create, but then disappear until remount of the share. (One weird thing too is that if you type in a path for a folder and try to browse to it in finder or terminal, then you can't, but if you use terminal to copy a file you know the path of, it can do that.)
