So… I left my (test) machine running over night and this morning it was unresponsive. Had to power it down and restart it that way. On restart it was
again also non-responsive.
I decided to just re-installed linux mint.
I did not realize that increments of 5GB meant that 1 node would be created for each 5GB. I thought that was just a total allocation of space to a node.
Running 10 nodes now. Machine not struggling at all.
I was trying to start 600 nodes by allocating 3TB yesterday. Ouch.
