I’m running a pretty simple two node OF3.8 cluster w/ Hazelcast. This morning, one node is reporting there is only 1 node in the cluster, with it’s own hostname in the list. The other node is reporting both nodes as being in the cluster.
Inspecting Hazelcast w/ JMX it is showing both nodes in the cluster, and clients connected to diverse nodes can communicate properly - So, first glace it seems to be a reporting issue with the Hazelcast plugin, rather than an actual clustering problem. There are no clustering related errors on either node, and both nodes reported 2 cluster members at startup.
Any useful information to grab to troubleshoot this?
