I have two nodes, 0.90.3, CentOS 6.4 on vSphere 5.1U1. Both machines have
two networks. An access VLAN (172.31.120.0/24) and a separate VLAN for all
replication/internal ES traffic (10.105.1.0/24)
At the beginning it just worked fine. But then, sometimes, if i restart one
node, it doesn't discover the other node anymore. I already have set
"network.publish_host: 10.105.1.x" on both nodes from the beginning,
because i wanted to have all this traffic on the separated VLAN. I can
restart the service or machine as many times i want, it doesn't work
anymore. After some time it can happen that it starts working again when
restarting ES. Haven't found a way to reproduce this.
Then I set "discovery.zen.ping.unicast.hosts: ["10.105.1.x"]" on the node
which wasn't able to rejoin the cluster and than it worked again. Changing
it back, doesn't work...
I thought ES uses the network defined on publish_host only for discovery if
it is defined. Am i wrong with that?
Would like to use multicast instead of unicast if possible, but i have to
be sure it works correctly.
