We are setting up run as real user but have run into a strange issue. When the drmaa external script is called it could not load the job json file. All permissions are set properly and the file exists. Upon attempting to run the script by itself this error is created. When loading a test script to open a file there is no issue. If the drmaa external script is run as root the same issue occurs. /mnt/ceph/home/galaxy/galaxy/files_directory/database/slurm/11.jt_json Traceback (most recent call last): File "scripts/drmaa_external_runner.py", line 157, in <module> main() File "scripts/drmaa_external_runner.py", line 146, in main load_job_template_from_file(jt, json_filename) File "scripts/drmaa_external_runner.py", line 43, in load_job_template_from_file f = open(filename, 'r') IOError: [Errno 13] Permission denied: '/mnt/ceph/home/galaxy/galaxy/files_directory/database/slurm/11.jt_json'
