Recording fails

Recommended Posts

DVR system was working great for months, but recently just stopped.  There where some system updates, but I'm not sure if that coincides with exactly when the problem started or not.

The TV recording drive is on a network drive.  Emby WILL set up the file folders, and create .nfo files for the season and episode(s) to record, so it does have access to the drive.

But when it goes to actually create the recorded .ts file, the log says:

I've looked at the logs a little more, and the actual files created, and my statement about the problem before isn't fully accurate.

Emby DOES create the TV Series and season folders, and it does save a valid "poster.jpg".

It also DOES create .nfo files "tvshow.nfo", "season.nfo", and the "{Episode Name and Number}.nfo" files, BUT they are all empty and the log file does say that permission is denied.

Best guess is that some file(s) are no longer owned by the correct user and/or group?


Any thoughts?

Hi, it looks like the server is being denied write access by your file system. If you can resolve that, then you should be good to go after that. Please let us know if this helps. Thanks.

If write access is being denied by the file server (a separate machine), how could Emby be able to create file folders, the poster.jpg file (including writing to it), as well as the empty .nfo files?

It's only writing to the .nfo files and writing the .ts that seems to be blocked.


The Emby server is a virtual machine, so I've restored to an earlier snapshot (two months old), and now recordings work again.  I'm still in the process of updating the virtual machine again, so it's still to early to tell if the problem will start again.

But the fact that it is working now, after the Emby virtual machine was regressed, that it's a change on the Emby server machine that is causing the failures and not the file server.

Another regress to the snapshot from a couple months ago, and all is fine again.  Emby is at the newest release of, and all backed up settings are restored.

Here is the list that the Centos8 system wants to update.  Is there anything there that you would consider more likely then another to potentially be the cause of the issue?

I was able to update everything EXCEPT the kernel packages.  Anytime I updated that group, DVR recording fails.... (?!?)
