Hi Gilles,
Yes, your configuration works with Netplan on Ubuntu 18 as well. However, this would use
only one of the physical interfaces (the current active interface for the bond) for both
networks.
The reason I want to create two bonds is to have enp179s0f0 as active for the public
network, and enp179s0f1 as active for the cluster network, therefore spreading the traffic
across the nics.
Regards,
James.

Hello,
I don't use netplan, and still on Ubuntu 16.04.
But I use VLAN? on the bond, not directly on the interfaces :
bond0 :
- enp179s0f0
- enp179s0f1
Then I use bond0.323 and bond0.324.
(I use a bridge on top to be more like my OpenStack cluster, and with more friendly names
: br-mgmt, br-storage, br-replic...)

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?
