      Workaround: node

      {a..d} should have filesystem barriers turned off.

      Description: All the lab <problem> setup scripts which would setup a cluster from scratch takes much time to finish. I haven't delivered the course yet, but I'd anticipate students asking about why reset between labs (I understand its to make it convenient for them to start at any point, without relying on the completeness of the earlier labs, I appreciate this effort) and about the delay in the script to finish.

      My suggestion would be to use nobarrier mount option for / in node{a..d}

      . Anyways, the nodes are VMs and as long as the fX box is up and running with barriers ON, VMs can run in nobarrier. I've tested this and there is a gain of around 3.5 mins.

      This is flagged as major (if not blocker) due to the number of times we rebuild the cluster in this course.
