I'm setting up iray server to run on a VM on my nas. I just want it to run as the master node, handling the images, db, etc.

Then my other machines with GPUs will run as slaves in the cluster.

Problem is, when I start the server, it just shuts down after a lot of "waiting on workers"

Is there a way to run the master without GPUs? Like a CPU only mode or something? Can't find anything in docs or googling
