Where are the scripts located? Where are you running them? Check the permissions on the file(s) to be sure you have access. Can you read the file(s)? Try re-mounting the volume. Make sure nothing else has the file(s) locked open.
The files are located on Goldman, I am attempting to execute them on my local machine. ls gives the permissions for the file as owned by root and read/writeable but not executable. chmod u+x file.py doesn't give an error but also doesnt change the listed permissions. The file isnt open anywhere. I can run the same file if I bring it to my local machine and change the permissions.
In cases where you have scripts, you can usually run them like this:
and you don't have to worry whether the executable bit is set. I have noticed sometimes it's hard to get binary executables to run from mounted file systems on the cluster, but I don't know yet under what conditions it doesn't work.
