I am in a sandbox playing with indexer cluster server management. My end goal is to play with and set up indexer discovery, but am stuck on trying to add a 3rd indexer peer to an existing 2 node indexer cluster. I have an Enterprise license with clustering available. I have my two indexer servers up and running great. I go to configure a third to bring into the fold and it tells me that the pass4Symkey is wrong, which I am about 99.99% sure it is not. I must be missing something about how to add a new peer to an existing established cluster.
