Hello, I am running 3 nodes cluster, version is 2.1.2
I dont really use streams, I just have one stream configured, who catches ware rare message…
I decided for now to upgrade just on on node (non master). I stopped all processe, run the upgrade commands
sudo rpm -Uvh https://packages.graylog2.org/repo/packages/graylog-2.2-repository_latest.rpm
sudo yum clean all
$ sudo yum install graylog-server
nad started elasticsearc, mongo and graylog processes.
The graylog gets in state RUNNING, but now I am getting hundreds of messages:
2017-02-22T11:02:33.797+01:00 WARN [DefaultStreamProvider] Unable to load default stream, tried 1041 times, retrying every 500ms. Processing is blocked until this succeeds.
MAybe reason for this is, that I have yet to upgrade the other 2 nodes ?
Or do I need somewhere to define default stream ?
Thanks for any advice.
