Permission to write recording

technicolour

Relatively new to tvheadend but I have got a bunch of it working, however, I'm having some trouble with reliable DVR.

It will sometimes work flawlessly and other times, presumably due to a transient error somewhere I'll only get partial recordings.

My latest issue is that it recorded the first half of a game, and then stopped. Looking at the logs, I can see an error stating it wasn't able to write the file, which is weird as it did so completely fine up till that point.

I have tvh running as a container and then have mounted via SMB the recordings directory from my NAS. The storage on my NAS is mounted as a collection via mergerfs (seems potentially relevant).

I think the next thing I want to try is to not record directly to my NAS, but then I have significantly more limited space, and I would like it to end up on my NAS. I could do a post record script to move it, but then I'll lose tvh being able to apply retention over my recordings.

Are there any gotchas around my similar setups that I should check off before going down paths that will limit my options?

So the first thing you could do is post the actual error message you mentioned, so people know exactly what it was. The second thing would be to check every time you get a partial recording what is recorded in the log, and again post the actual entries so people can see.

I think you have to decide what is more important to you - reliable recording or full TVH functionality in the short term.

Two errors in the log:

Unable to change permissions -- Operation not permitted
Write failed -- Permission denied

So the part I don't understand is how if it's a permissions issue, how any data was written to begin with? Is it possible for the fle handle to be created, and be open for writing and then only when for some reason it needs to restart it fails?

I can see that the directory is 755 and the .ts file itself is 744 with my expected owner/group. It could be something around the uid the container is running as and it conflicting when coupled with an SMB share? Maybe next step is to try 777 in the recording config instead of the defaults?
