I am playing with a two-node grid. Host 1 (NetBSD Jail 1): Introducer + Node + Helper + WebUI Host 2 (OmniOS Zone 1): Node + WebUI Host 3 (OmniOS Zone 2): Gateway + WebUI
For technical reasons, I need to reboot Host 1 (Introducer). Obviously Host 2 & Host 3 lose connectivity to the Introducer and go into 'disconnected from introducer' red mode. Once the Node and the Introducer are brought up again on Host 1, I expect Host 2 and Host 3 to find the introducer again, and turn happy and green. However this is not so, they are both still sitting without a connection to the introducer. Host 3 still has its connection to Host 2, but nothing else. It was left for about 20 minutes, but no connection was re-established. It takes a "tahoe restart" on Node 3 to get it to reconnect to the introducer. Interestingly, after Node 3 is restarted, Node 2 also suddenly discovers the introducer without needing a restart, however it does NOT discover node 1 - only connectivity to introducer returns. It takes a further restart of Node 2 before it reconnects to Node 1. There is no NAT between nodes 1 and 2, they are on the same subnet. Host 3 is behind a NAT and firewall. Is there any reason why this is the case?
