I’m currently setting up a new Graylog 2.2 Cluster with four nodes. One node is bringing trouble to the whole cluster.
Node 1 is the master
Node 2 brings the trouble if he is running
Node 3 works fine
Node 4 works fine
If I start Node 2 the cluster is loosing is master server or at least it cluster state because I access the webinterface only on the master node.
On the overview page I get this message:
“There was no master Graylog server node detected in the cluster.”
In the logfile of the master node I see the following message every second:
2017-04-05T10:25:57.802+02:00 WARN [NodePingThread] Did not find meta info of this node. Re-registering.
In the logfile of the second node is no error or anything suspect to see.
I tried to set a new node-id on node 2, to register it as a new node, but this didn’t helped.
I checked the configs three times. The master flag is only set on node 1.
I Posted the logfiles on Gist - Graylog Logfiles
