Hello.
I have a strange problem with my cluster:
- 6 x dell R730 nodes with 4x10Gbit ethernet
- 2 x Cisco Nexus 3000 series
Networking is with a single 4 port LACP bond, with 2 vlans (for ceph and management), and SDN with VLAN and QinQ zones.
Only with node 4, 802.1q guests can't communicate with other nodes, but guests with ethernet in vlan zones, have no problems at all.
In /var/log/ifupdown2/ folder, I have a new folder every 10 seconds. Is normal or there is something wrong that could explain my network problem ?
