Is it possible to expand the no of master nodes? Are the first 3 always designated as masters, with the 4 and subsequent nodes serving as compute nodes? Can we modify the host's role?
I initially believed that when a master node went down, a compute node would be promoted to take its place to maintain a count of three master nodes. However, I've since realized that this isn't the case. How can we go about replacing or adding more master nodes?
I noticed that the promotion process only begins after completely removing a node. Stopping the host does not trigger the promotion.

It's probably technically possible but wouldn't currently be supported. If you need this I'd submit an issue via GitHub.

Correct.

Similar issue in our case, two masters going we lost the cluster even the third one is still there… it didn’t promote compute nodes to master.
