[Starlingx-discuss] AIO Duplex Setup with 2 NICs
Hi everyone, Is it possible to setup an AIO Duplex (kubernetes + openstack) configuration with servers that have only 2 NICs? I did a quick test last week and pointed the DATA0IF interface to the same interface as mgmt and cluster-host but the installation failed. I seem to lose connectivity with the 2nd controller while applying the stx-openstack application charts. Would configuring some VLANs solve the problem? Or is this something that is not currently supported? If it is indeed supported, do you have any pointers/recommendations? Thanks! Marc
Hi, While I haven't tried it, I believe you can create VLAN based interfaces and assign them to data interfaces, based on: https://docs.starlingx.io/configuration/host_interface_network_config.html Try doing a "system host-if-add controller-0 -V ...". But if you want to use SRIOV, I believe it might make more sense to assign entire NIC to DATA0IF and use VLAN intrrfaces for MGMT_IF and OAM_IF. Hope this helps.

Thanks for the info. Followed the guide and modified my VLANs config accordingly. DATA0IF now has it's own dedicated interface. I reinstalled the OpenStack application but it failed while installing the openstack-libvirt chart. Install log: https://pastebin.com/FAdV3tMe neutron-ovs-agent-controller-0-937646f6-dprsc_openstack_neutron-ovs-agent-init*.log seems to also point to an error: https://pastebin.com/GcC2bjBj I'm also seeing these messages appear periodically in dmesg: [11998.657984] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready [11998.658070] IPv6: ADDRCONF(NETDEV_UP): cali29ecf54f2e7: link is not ready [11998.658073] IPv6: ADDRCONF(NETDEV_CHANGE): cali29ecf54f2e7: link becomes ready [11998.658079] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready [11998.783788] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready [11998.783869] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready Any help appreciated, Marc

I'm also seeing these messages appear periodically in dmesg:
I found the following bugs related to the "Unhandled error: NoSuchOptError: no such option vf_management in group" error: https://bugs.launchpad.net/starlingx/+bug/1889023 and https://bugs.launchpad.net/neutron/+bug/1888920 The former has some workaround for StarlingX. The latter says that maybe SRIOV was not enabled in BIOS. Again, just info I found. Hope it helps. Thanks Pratik
