Almost all media files can't be played

Hey,

12 hours ago my Plex server was working without issues, playing any media files of the libraries. Now it seems that something happens because I cannot play literally nothing. I tried it from different devices (TV, smartphone, laptop, Plex for Kodi through Odroid C2 with LibreElect) but none of them worked. The server has been already rebooted.

It’s a Ubuntu 16.04 machine, last PMS version installed. Attached you can find a log that maybe helps!

Thanks everyone.

ERROR - An error occurred reading the file: /home/plex/series/ ....

Is this a network mount or an internal / external drive? However, something is wrong with your media storage. Plex is unable to access it. If it’s local storage please perform a file system check. If it’s remote storage, check the connection. And also make sure the Linux user permissions are still correct and user plex is able to access the files.
