This issue may somehow be of my own doing but I'm going to ask because I can't work out why.
I have a 2 node cluster, both notes use the same x.x.x.112/28 IPs. Node 1 is x.x.x.122 and node 2 is x.x.x.123
The issue I keep getting is sometimes the VMs from one node can't connect to VMs on the other node using the IPs, they won't even ping between the IPs.
The only thing I can think is that the IPs have previously been used for VMs on both nodes, and or been migrated back and forth during development and testing. Would that cause network issues that stop the VMs from seeing other VMs on the opposite node? The PVE nodes themselves are able to ping each node, it's on the VMS that can't communicate.
The only way I appear to be able to fix it is by rebooting the Node, which isn't really feasible sometimes.
What could my issue actually be? Whats' likely to be causing it?
