We have a 6.6.2 cluster in prod that appears to have no overseer. In /overseer_elect on ZK, there is an election folder, but no leader document. An OVERSEERSTATUS request fails with a timeout.
I’m going to try ADDROLE, but I’d be delighted to hear any other ideas. We’ve diverted all the traffic to the backing cluster, so we can blow this one away and rebuild. Looking at the Zookeeper logs, I see a few instances of network failures across all three nodes. wunder Walter Underwood wun...@wunderwood.org http://observer.wunderwood.org/ (my blog)
