[ovirt-users] Issue with a LACP bond interface.

The config details: root@lv426 network-scripts]# cat ifcfg-bond0 # Generated by VDSM version 4.19.31-1.el7.centos DEVICE=bond0 BONDING_OPTS='mode=4 lacp_rate=1 miimon=100 xmit_hash_policy=2' BRIDGE=ovirtmgmt ONBOOT=yes MTU=1500 DEFROUTE=no NM_CONTROLLED=no IPV6INIT=no [root@lv426 network-scripts]# cat ifcfg-eno1 # Generated by VDSM version 4.19.31-1.el7.centos DEVICE=eno1 MASTER=bond0 SLAVE=yes ONBOOT=yes MTU=1500 DEFROUTE=no NM_CONTROLLED=no IPV6INIT=no [root@lv426 network-scripts]# cat ifcfg-enp11s0 # Generated by VDSM version 4.19.31-1.el7.centos DEVICE=enp11s0 MASTER=bond0 SLAVE=yes ONBOOT=yes DEFROUTE=no NM_CONTROLLED=no IPV6INIT=no [root@lv426 network-scripts]# cat ifcfg-enp2s0f0 # Generated by VDSM version 4.19.31-1.el7.centos DEVICE=enp2s0f0 MASTER=bond0 SLAVE=yes ONBOOT=yes MTU=1500 DEFROUTE=no NM_CONTROLLED=no IPV6INIT=no [root@lv426 network-scripts]# cat ifcfg-enp2s0f1 # Generated by VDSM version 4.19.31-1.el7.centos DEVICE=enp2s0f1 MASTER=bond0 SLAVE=yes ONBOOT=yes MTU=1500 DEFROUTE=no NM_CONTROLLED=no IPV6INIT=no [root@lv426 network-scripts]# cat ifcfg-ovirtmgmt # Generated by VDSM version 4.19.31-1.el7.centos DEVICE=ovirtmgmt TYPE=Bridge DELAY=0 STP=off ONBOOT=yes BOOTPROTO=dhcp MTU=1500 DEFROUTE=yes NM_CONTROLLED=no IPV6INIT=no DNS1=10.100.100.1 DNS2=10.1.2.2 [root@lv426 network-scripts]# cat /proc/net/bonding/bond0 |grep Slave *Slave* Interface: eno1 *Slave* queue ID: 0 *Slave* Interface: enp2s0f0 *Slave* queue ID: 0 *Slave* Interface: enp2s0f1 *Slave* queue ID: 0 *Slave* Interface: enp11s0 *Slave* queue ID: 0 As you can see by the above all 4 interfaces are configured and up properly and working. I've configured them using the command: vdsClient -s 0 setupNetworks bondings='{bond0:{nics:eno1+enp11s0+enp2s0f0+enp2s0f1,options:mode=4 lacp_rate=1 miimon=100 xmit_hash_policy=2}}' It's all good. But when I reboot interface3 enp11s0 is not part of the bond, [root@lv426 ~]# cat /proc/net/bonding/bond0 |grep Slave *Slave* Interface: eno1 *Slave* queue ID: 0 *Slave* Interface: enp2s0f0 *Slave* queue ID: 0 *Slave* Interface: enp2s0f1 *Slave* queue ID: 0 And looks like it's had it's bonding config removed b y VDSM. [root@lv426 network-scripts]# cat ifcfg-enp11s0 # Generated by VDSM version 4.19.31-1.el7.centos DEVICE=enp11s0 ONBOOT=yes MTU=1500 NM_CONTROLLED=no If I re-=run the vdsClient command and if down/ifup the interface it happily rejoins the bond and carries on working perfectly. For the life of me I can't figure out what I'm missing / done wrong.
