We are experiencing issue where entire cluster suffers serious cluster visibility issues when one of our nodes went down. asinfo service reports that all nodes experiences cluster integrity issues and half of the nodes cluster visibility issues (AS: 3.5.14, +10 nodes in the cluster).
We had similar situation few weeks ago but lucky we managed to get missing host up and running quite fast and (as far as I remember) putting it back has resolved the issue.
Is there any way how the cluster can be bring into shape in such situation? Rolling restart is probably one option, but quite painful. Maybe there is other way?
