Some content comes and goes when scanning, some content is simply skipped

Thanks! - No, no hard links is used in my setup.

I guess the guy could just hide the hard links simply by exposing the files over a protocol that would hide them. But interesting find, it appears to me again that there is some very strange magic going on in the Scanner :smiley:

In my case everything is mounted in over CIFS from a Synology NAS; there are no local media files at the Plex server.

The move between the staging and the final libraries is a simple file move inside the same CIFS mount.

I am very aware that CIFS mounts sometimes do come with caching issues, especially with files being edited, but this is not the problem here. The problem is that the Scanner consistently skips particular files that are very present and accessible in the file system.

CIFS mount parameters:
type cifs (rw,relatime,vers=default,cache=strict,uid=0,noforceuid,gid=0,noforcegid,file_mode=0755,dir_mode=0755,soft,nounix,serverino,mapposix,rsize=1048576,wsize=1048576,echo_interval=60,actimeo=1)
