I am running OMV Server (latest OMV4 version) with the most recent version of Plex Media Server (version 220.127.116.114, non-docker). All my media is on a unisonfilesystem drive. Yesterday I saw that mergerfs has an update to version 2.26.2 (previous version: 2.25.1). After upgrade, Plex is not able to find any files. It always says "File not available". I can play everything with VLC or MPC. Media files on drives outside UnionFS is also works with Plex.
Now I downgraded mergerfs to version 2.25.1 again and everything works fine.
Anyone has the same problem or know a solution?
