3. Alternatively, use Prometheus:
```promql
node_network_mtu_bytes{device!~"^(veth|docker|flannel|cali|tun|tap).*"} < 9000
node_network_mtu_bytes{device!~"^(veth|docker|flannel|cali|tun|tap|ovn-k8s-mp|br-|lo|ovs-system).*"} < 9000
```
4. Verify MTU consistency across all nodes and all switches in the storage fabric.

## Mitigation

1. Ensure the node network interfaces are configured for 9000 bytes
2. Ensure switches in between the nodes support 9000 bytes on their ports.
