Hi, I am currently building a 10 node Ceph cluster, each OSD node has 2x 25 Gbit/s nics, and I have 2 TOR switches (mlag not supported). enp179s0f0 -> sw1 enp179s0f1 -> sw2 vlan 323 is used for ‘public network’ vlan 324 is used for ‘cluster network’ My desired configuration is to create two bond interfaces in active-backup mode: bond0 - enp179s0f0.323 (active) - enp179s0f1.323 (backup) bond1 - enp179s0f0.324 (backup) - enp179s0f1.324 (active) This way, the public network will use switch1, and the cluster network will use switch2, under normal operation. I am, however, having an issue implementing this configuration in Ubuntu 18.04 with netplan (see configuration at the end of this post). When I reboot a node with the below netplan configuration, the bond interface is created, but the vlan interfaces are not added to the bond. I see the following errors in the log: systemd-networkd[1641]: enp179s0f0.323: Enslaving by 'bond0’ systemd-networkd[1641]: bond0: Enslaving link 'enp179s0f0.323’ systemd-networkd[1641]: enp179s0f1.323: Enslaving by 'bond0’ systemd-networkd[1641]: bond0: Enslaving link 'enp179s0f1.323’ systemd-networkd[1643]: enp179s0f1.323: Could not join netdev: Operation not permitted systemd-networkd[1643]: enp179s0f1.323: Failed systemd-networkd[1643]: enp179s0f0.323: Could not join netdev: Operation not permitted systemd-networkd[1643]: enp179s0f0.323: Failed If I manually run ’systemctl restart systemd-networkd’ after boot has completed, then the bond is successfully created with the vlan interfaces. Does anybody have a similar configuration working specifically with netplan/networkd? Could you please share your configuration?
