Hi all,
We have two nodes in Graylog cluster 2.1.0. There is Error: There was no master Graylog server node detected in the cluster. This error is every 10 seconds, there is No notification (green) and then this error - see system messages. "Certain operations of Graylog server require the presence of a master node, but no such master was started. Please ensure that one of your Graylog server nodes contains the setting is_master = true in its configuration and that it is running. Until this is resolved index cycling will not be able to run, which means that the index retention mechanism is also not running, leading to increased index sizes. Certain maintenance functions as well as a variety of web interface pages (e.g. Dashboards) are unavailable. " Could you give me advice how to solve this error? discovery.zen.minimum_master_nodes: 2 gateway.recover_after_nodes: 1 Elasticsearch sluster - green NTP enabled: yes NTP synchronized: yes cat /etc/graylog/server/server.conf One node is is_master = true, second node is is_master = false System messages: Timestamp Node Message 2016-10-20T12:21:27+02:00 7e58c1ec / hostname001 Notification condition [NO_MASTER] has been fixed. 2016-10-20T12:21:13+02:00 7e58c1ec / hostname001 Notification condition [NO_MASTER] has been fixed. 2016-10-20T12:21:10+02:00 7e58c1ec / hostname001 Notification condition [NO_MASTER] has been fixed. 2016-10-20T12:21:00+02:00 7e58c1ec / hostname001 Notification condition [NO_MASTER] has been fixed. 2016-10-20T12:20:47+02:00 7e58c1ec / hostname001 Notification condition [NO_MASTER] has been fixed. 2016-10-20T12:20:40+02:00 7e58c1ec / hostname001 Notification condition [NO_MASTER] has been fixed. 2016-10-20T12:20:36+02:00 7e58c1ec / hostname001 Notification condition [NO_MASTER] has been fixed. 2016-10-20T12:20:33+02:00 7e58c1ec / hostname001 Notification condition [NO_MASTER] has been fixed. 2016-10-20T12:20:23+02:00 7e58c1ec / hostname001 Notification condition [NO_MASTER] has been fixed. 2016-10-20T12:20:19+02:00 7e58c1ec / hostname001 Notification condition [NO_MASTER] has been fixed. 2016-10-20T12:20:14+02:00 7e58c1ec / hostname001 Notification condition [NO_MASTER] has been fixed. 2016-10-20T12:20:10+02:00 7e58c1ec / hostname001 Notification condition [NO_MASTER] has been fixed. -- You received this message because you are subscribed to the Google Groups "Graylog Users" group.
