Tvheadend

Hi all,

after some days of research in the web I decided to open a thread here. I have the problem that DVR recordings can only write files with a size of 2GB. The TVHeadend log then looks like this:

2021-04-11 10:31:18.930 dvr: Unable to change directory permissions to "775" for "/config/LUKE!-Die-Schule-und-ich---VIPs-gegen-Kids" (keeping "755")

I am using TVHeadend in a Docker container from this image: https://hub.docker.com/r/linuxserver/tvheadend in version: HTS Tvheadend 4.3-1923~gaaca05cc1

The data is currently written in the container to /config, which I have mounted from the host. When I connect to the running container via bash:

docker exec -it tvheadend2 /bin/bash

I can create larger files without problems in the corresponding folder of the running container:

pi@raspi:~ $ docker exec -it tvheadend2 /bin/bash
root@650787120ab5:/# cd config
root@650787120ab5:/config# dd if=/dev/zero of=testfile.ts bs=1M count=5000
5000+0 records in
5000+0 records out
5242880000 bytes (5.2 GB, 4.9 GiB) copied, 28.998 s, 181 MB/s

The dvr config looks like this:

{
        "enabled": true,
        "name": "",
        "profile": "45d9bec4fa1465796a1751925f767fec",

        "date-in-title": false,
        "time-in-title": false,

        "omit-title": false,

        "autorec-maxsched": 0,
        "skip-commercials": true,
        "warm-time": 30
}

I therefore suspect that the problem may be somewhere in TVHeadend or is maybe a wrong configuation? Do you have some suggestion how to fix this problem?

Thanks & best regards!
Timo
