Clustering woes

[Vadim Maksimenko]

Hello everyone,

Something weird.

First of: I have suddenly discovered that cluster name CANNOT contain uppercase letters. WHY?! When cluster name contains uppercase letters connect is impossible -- writes some gibberish about refused connection. REALLY?!

Next: OK, now I create a cluster with lowercase name. Two nodes have managed to join successfully (3 in total). The fourth one cannot connect:

Establishing API connection with host 'a.b.c.d' TASK ERROR: 500 Can't connect to a.b.c.d:8006 (Connection refused)

Most likely I will never abandon VMware. Their products are cumbersome, unwieldy, but they ALWAYS work.

i don't think thats true, i just tested it with the cluster name 'TESTcluster' and it worked without problems... there must be something else that prevented it
(though without the error and the commands it's impossible to say what)

seems like a network issue. are the nodes in the same subnet? if you used a dns name, can the nodes resolve them properly?
