@dereneaton I've been running ipyrad intensely on our HTC network for about a year. Long story short, we recently had to switch to having the working directory for ipyrad on the execute node instead of a large drive mounted to HTC network. My job keeps failing and all signs point to running out of disk space, but both the ipyrad and HTC error messages are blank. Is ipyrad coded to print an error message if it runs out of disk space to write to? If definitely yes, than I might have other issues to hunt for, but if not, things make sense.
