Lustre File Locking #161

Open crutching opened 6 years ago

crutching commented 6 years ago

Getting following error message trying to lock file before a citation is displayed. We are working on a lustre fs, which i assume is the problem.


Traceback (most recent call last):

Are you sure you are mounting the file system with the flock option? Should be needed to enable file locks on lustre.
