run-command executes without a respones #218

Closed thagorx closed 6 years ago

Flintrock version: 0.9.0
Python version: 3.5
OS: lubuntu 16.04

Part of setting up my cluster is that I create large swap files on the ephemeral storage with: flintrock run-command my_cluster 'sudo /bin/dd if=/dev/zero of =/media/ephemeral1/swap.1 bs=1M count=100000' the command gets executed with out a problem but I never get a 'command completed' response from flintrock when the swap size is large.

So to be clear, Flintrock is not hanging, but you are not seeing the output you expect. Is that right?

Can you post the flintrock run-command output you are seeing for the problematic command, plus the output you see for another command that works "normally"?
Can you show me what you get when you run the problematic command directly on one of the nodes? What's the return value of the command ($? in Bash)?

Closing this due to inactivity. I'd be happy to reopen it if actionable information is added.
