Permission denied when running as local user

Deadline
1

Hi everyone,

We are having an issue with a lot of our machines. We have set up Deadline to run as a user dedicated to deadline with all permissions, and we have set the SlaveDataRoot in the desktop.ini to C:/Temp/Deadline10. Yet, we often get issues on machines, where it’s trying to access six.py in a temporary folder in the dedicated deadline user’s local app data folder.

This behavior is bugging us for several reasons. We have set the SlaveDataRoot, so we expect deadline not to use the local AppData folder. Furthermore, the user the job should be running as, definitely has permission to that folder. Therefore we do not understand why it fails with the error ‘Permission denied’ trying to import six.py from the local AppData folder.

Here is a log of the error:

Hello @Mads_Hangaard

Thanks for reaching out. SlaveDataRoot only keeps jobsData and plugin when there is a job dequeued by Worker these directories get populated. While the AppData/Local/Thinkbox/… gets the copy of Application Data all the time if Deadline is running. I do not think you can change this location.

For the error you are getting, usually the reason is that the running Worker doesn’t have permission to access the contents of the active pythonAPIs directory or the directory doesn’t exist.

Below is the workaround:

This can happen when the Worker’s local storage has a mix of permissions due to being started under different users. Basically this means that the Worker doesn’t have permission to read the PythonAPI files under the current user. The fix is to stop the Worker then empty the Thinkbox\Deadline10\pythonAPIs directory. Then when the Worker gets started it’ll copy the files with permissions it can use.

Thank you, we ended up deleting the folder on all the machines, and it seems to have worked. Thank you.
