Debian NextPVR on Cifs share

[Oempa]

NextPVR Version: 5.2.7.220410 runs here quite smooth in an Debian LXC on Proxmox
Installed from the deb package (not a docker)
But it fails when the live TV buffer directory or the recording directory are changed to a Cifs share

CIfs share is mounted on the host
And then added as a mountpoint to the LXC
I'm doing the same in another LXC with a torrent client without problems


root@NextPVR:/mnt/download# ls -la PVR
total 2
drwxr-xr-x 2 nobody nogroup  0 Jun 21 12:44  .
drwxr-xr-x 2 nobody nogroup  0 Jun 21 06:25  ..
-rwxr-xr-x 1 nobody nogroup 26 Jun 21 12:44  test.txt

I can create and edit files there with Nano there
PVR can create directories and files but the size stays 0
I'm not very good with Debian and quite lost now

I regularly record to a cifs share from linux without issue. You can check to see if user nextpvr is a member of norgoup.

sudo cat /etc/group | grep nogroup

From the LXC
Root@NextPVR:/mnt/download# cat /etc/group | grep nogroup
nogroup:x:65534:

Maybe try adding nextpvr to nogroup and see if it makes a difference. If not not check the permissions of /mnt/download which I assume is the mount point.

Ultimately this will work you probably just need to read up more on Linux if you plan to use it.

I tried this: usermod -a -G nogroup nextpvr
So the logic that I can write manually is because I do that as "root" and not NextPVR ?
But I don't get why NextPVR can create the file but is unable to put data in it

su - nextpvr
Now I can create a directory and also create/edit a txt file there in the mounted share
So the user seems to have write rights..

Next I changed the LXC to privileged and write directly to the storage device on the host
As root I can write, no problem. But again NextPVR can't write

[mvallevand]

Maybe try noperm on the fstab beyond that I can't help further since I don't know the specifics of your system, cifs, or your share fstab values. To tell you the truth I don't really want to help to that level for each user anyway, but it will work.

Hi there,

I'm a first time nextpvr user and I have the exact same problem when trying to record to an smb-share. The permissions are set correctly. I can write to the share as user nextpvr and the nextpvr-software can aswell, since it does create the ts- and ts.map-files. Yet they both have 0 bytes. I can confirm the files are empty (same on my nas via gui or ssh, on the mounted share in windows and on the pi I'm trying to run nextpvr on).

As soon as I try to play a running recording from the web interface it fails to play (the first time), but then it actually starts recording and the ts-file starts growing. This workaround naturally is no viable solution, but it might give some insight into what causes the issue.
When I do watch the recording I can confirm it only started after trying to play it via the web interface.


When searching the forums I find this problem a few times and nobody really seems to have an answer. It's always "must be the wrong permissions". But it's clearly not that simple as users (me included) can write to their share as user nextpvr.
Adding noperm to the fstab entry doesn't make a difference for me btw.


Cheers aimaim

In either thread, this doesn't sound exactly like a permissions issue.  Create a new thread attaching the zipped NextPVR logs which show you starting the recording then let it record fro a few minutes and then cancel the  recording.

You're way to fast for me. I already posted in the other thread 
I'll do that as soon as I figure out where to find the logs 

Edit: Ok got it: /var/opt/nextpvr/logs/

It's best to use the 'Log Files' button on the Settings->About screen. It causes the most recent messages to be flushed to disk, and zips them up for you.
