Hi all

I have a cluster with vswitch active - active

I have new nodes to expand and I did theses steps below 

1 -  root@ahv# ./network_configuration to configure ips and vlan tag

2 - Configure lacp 

    2.1 ssh root@192.168.5.1 "ovs-vsctl set port br0-up other_config:lacp-time=fast"

    2.2 ssh ovs-vsctl set port br0-up other_config:lacp-fallback-ab=true

    2.3 ssh root@192.168.5.1 "ovs-vsctl set port br0-up lacp=active" nutanix@CVM$ ssh      2.4 ssh ssh root@192.168.5.1 "ovs-vsctl set port br0-up bond_mode=balance-tcp"

3 - Expand cluster

 The nodes were joined success in the cluster, but when I checked the vswitch configuration of theses nodes was changed to active - backup

Did I do something wrong?

 

What better way?

 

Thank you

If the nodes are correctly in the cluster you can re-configure the vswitch to lacp again. AOS will makes sure that all nodes are correctly configured then.
