PostProcessing suddenly not working #1567

Closed juliemars closed 5 years ago

juliemars commented 5 years ago

Hi All

Looking for some advice, I have been using LazyLibrarian for awhile and it was working fine. The last book it downloaded on the 29th August worked fine, it post processed fully. Yesterday it downloaded a couple of books but the post processing failed

My setup is as follows: Raspberrypi with NZBGet for downloading. books get placed into /media/downloads/completed/books on the PI when downloaded. This folder is shared second Raspberrypi has LazyLibrarian installed via git, and has a mapped folder to the first PI. The ebooks are then moved to a network drive, plugged into the router, which has no credentials assigned to it.

the logs show as:

18-Sep-2018 01:10:53 - ERROR :: POSTPROCESS : postprocess.py:processDir:711 : Postprocessing for TITLE-AUTHOR has failed: Unable to move file /media/downloads/Completed/Books/AUTHOR TITLE retail epub/AUTHOR - SERIES - TITLE (retail) (epub).epub to /media/Router/Backups/Ebooks/AUTHOR/SERIES/TITLE - AUTHOR.epub: OSError [Errno 13] Permission denied: '/media/Router/Backups/Ebooks/AUTHOR/SERIES/TITLE - AUTHOR.epub' 18-Sep-2018 01:10:53 - ERROR :: POSTPROCESS : postprocess.py:processDir:735 : Unable to rename /media/downloads/Completed/Books/AUTHOR SERIES TITLE retail epub, OSError [Errno 13] Permission denied: '/media/downloads/Completed/Books/AUTHOR SERIES TITLE retail epub.fail' 18-Sep-2018 01:10:53 - WARNING :: POSTPROCESS : postprocess.py:processDir:736 : Residual files remain in /media/downloads/Completed/Books/AUTHOR SERIES TITLE retail epub

so I know it's a permissions issue that has appeared, no idea why though. Not sure if it is a permission on the first PI or the router, that I need to fix.

Any ideas how I can fix this?

Looks like write permissions on /media/downloads/Completed/Books/AUTHOR SERIES TITLE retail epub as we can't rename it, and we can't move it to /media/Router either. Maybe NZBGet has saved the file read-only, or maybe a mapping permissions issue?

thanks philborman it must be a mapping permissions issue then, no idea as I have made no changes to this. Oh well will have a play and see if I can work it out.

EDIT: I am really confused I logged in as the user lazylibrarian is running as, went to both directories and ran cat > sample.txt the file appeared so no idea now why it's not working oh well will just move them manually

Few things you can check What is the permission on the file /media/downloads/Completed/Books/AUTHOR SERIES TITLE retail epub, ls -lh or similar Might be worth checking the sd cards too. As you are on raspberry pi I guess the sd card is being used for storage. Some sd cards will start to go read-only before they fail. We could fairly easily get lazylibrarian to tell us the permissions it thinks it has, currently the error code just says OSError [Errno 13] Permission denied but doesn't tell us what it was trying to do at the time or what permission was refused. Would need a little editing if you are up for it.

Hi

using ls -lh I get the following on the router directory:

drwxrwxr-x 1 pi root 0 Sep 18 13:42

The Downloads is: drwxr-xr-x 2 pi root 0 Sep 18 20:55

the PI with NZBGet on it has a HDD for storage, I checked it and it's fine. The SD Card looks fine but to be safe I have cloned it and swapped it. I have swapped the download locations to a second network drive and it seems to be working so I will leave it as it is for now. Thanks for the help though

ok, I will close this for now. Added some extra debug messages to the logs if rename/move fails so if it happens again we will get more info on what's wrong.
