PMS running on OpenMediaVault, i.e. debian, Linux 6.1.0-0.deb11.6-amd64
When ‘recording’ from a tuner, PMS is creating files and folders without write permissions for group. However I need group write permissions for another actual user in the same group to be able to sometimes manipulate the files that PMS has created. I don’t really want to change the default umask for all users, so…
How can I set the plex user’s umask to 002 instead of 022?
So far I just chmod what PMS has created to add group write permissions, but I don’t want to have to keep doing this. I want to configure PMS to do what is required in the first place.
Thanks @ChuckPa, however those instructions indicate 4 possible settings:-
UMask=002
Umask=002
UMask=0002
Umask=0002
With a warning that it’s important to get it right (I’m guessing otherwise it simply won’t work), but no indication of which is correct, nor how to find out.
I suspect this should work:-
UMask=0002
Can you confirm that for a debian based system?
Ignore that question.
‘systemctl show plexmediaserver’ includes UMask=0022, so that will be the correct format.
All sorted. Thanks again.

Those instructions support all variants of Linux Plex supports; inclusive of the NAS Linux systems.
That’s why the warning exists 
The installer does a lot for users but there are some things it can’t possibly know nor safely assume. Sometimes RTFM is your friend
