We set up a semi-large cluster which has worked without issue, so we thought, until recently.
Rancher version: 2.3.2
Environment: vSphere
OS: RancherOS
Many of the weave pods have been restarting, constantly with and I’m not certain the safest way to resolve this error which is on the majority of weave pods:
Network 10.42.0.0/16 overlaps with existing route 10.42.0.0/24 on host
We didn’t modify anything regarding the networks when launching, having this in the cluster.yaml
