recording system path error, if changed from default

Added by Michael Bratge 2 months ago

I use TVHeadend with a raspberryPi 4B with the Rpi TV HAT. I had the same behavior on a rpi3b+ as well before.
It works in general as long as the recording system path is the default: /home/hts/ or a subdirectory.
But this is the internal system memory, not suited for mass data like videos. If I change the recording path away from /home/hts/, the recording does not work.
I set the user rights in the target directory to 777, I added user hts to group pi and vice versa, nothing helps.
(Changing the mount point of the HDD is actually not a solution, because my system always mounts on /media/pi, don't know yet why.)
Can anybody help me to solve this problem?

What do you have "Storage path:" in Configuration/Recording set to?

Can you post the result of 'ls -l' for each part of the path - e.g. if the path is /foo/bar/baz , the post the output of 'ls -l /foo' and ls -l /foo/bar'.

Messing with group pi won't change anything.

Your drive is mounting at /media/pi because you don't have an fstab entry for it.

my fstab has an entry, but something seems to be wrong so that it doesen't work:
UUID=083C36F93C36E0FC /home/hts/ ntfs-3g nofail,rw,auto,nls=utf8,gid=hts,uid=hts 0 0
here I am still searching for the solution, but that's another issue.

Please paste the actual string from your config.

RE: recording system path error, if changed from default - Added by Michael Bratge 2 months ago

actually I got solved my problem with the fstab, so I can config a running system, the actual Storage Path is
/home/hts/toshiba/Video/TV-Aufnahmen
this works now,

but with the path's
/media/pi/toshiba/Video/TV-Aufnahmen (ext. HDD) and
/media/pi/test (int. memory)
it does not work, though all necessary rights are given.

I can live now with my solution, but I can reproduce the error behavior on 2 devives. Maybe it is interesting in general.
Do you work with a Raspi, an if, can you reproduce the error?

For with user?
Can you report tvh service user and group?

RE: recording system path error, if changed from default - Added by Michael Bratge 2 months ago

the directory /home/hts has user hts and group hts
I included user ths to group pi an user pi to group hts.

How to get out tvh service user and group?

in my case

# ps aux | grep tvheadend

/media/pi is drwxrw-rw- not drwxrwxrwx

Also /media/pi/toshiba should be /media/pi/TOSHIBA [case is important].

are execution rights necessary to write there?

I changed my path to lower case, the upper case came from the HDD's default name.

Let's test further till it works with directory /media/pi/test, this is internal memory and so we don't merge ext. HDD problems.

I changed now the rights:
[email protected]:/media $ sudo chmod x pi
[email protected]:/media $ ls -l
insgesamt 8
drwxrwxrwx
11 pi pi 4096 Apr 6 11:48 pi

[email protected]:/media/pi $ ls -l
insgesamt 36
drwxrwxrwx 2 hts hts 4096 Apr 4 11:57 test

and it still does not work.

Do you know the meaning of the "+" at the end of drwxrwxrwx rights of pi?

Execution rights are necessary to read the directory.
Rule of thumb: always give directories x permission unless you have a specific reason not to.

OK, as long as your path in TVHeadend config exactly matches what ls -l shows.

drwxrwxrwx 2 hts hts 4096 Apr 4 11:57 test

and it still does not work.

This may be related to your problem.

To test that TVH can write to a location, use the hts user, e.g.

sudo su hts
touch /media/pi/test/testfile

This should create a 0 byte file called testfile in /media/pi/test/ [you can delete it afterwards]

If that doesn't work, you should get an error message indicating what the problem is. You can also try stepping back to using /media/pi/ and /media/ until you do succeed - that will isolate what part of the path is a problem.

It's important that you are able to create a file using the exact same path you have configured in TVH [ for example, it's not sufficient to cd to /media/pi/test/ and then 'touch testfile', you must touch using the absolute path].

If your test as user hts works, then TVH should work OK.

When you're done testing as hts, you can get back to the original user with 'exit'.

I recomend few years ago, same thing to be implemented inside TVH.
It can be a buton to test new location.

RE: recording system path error, if changed from default - Added by Michael Bratge 2 months ago

Yes, somehow behind the "+" seems to be the problem. I made a new Path /media/test and there everything is ok.

I followed your link, but option -e at command ls is unknown
[email protected]:/media $ ls -e
ls: Ungültige Option -- e

So, because it is clear now that it was an individual problem with my configuration and not an overall problem, and I don't need this folder anymore, I deleted it..
.. and I think we can close the thread here.

Thank you once again for the time you took to help me.
