In OpenShift 4 adding worker nodes using a bond network with the link-aggregation 802.3ad fails to create the IPv4 stack

Solution Verified - Updated -

Issue

  • During the node firstboot all the interfaces are created but no IPv4 address is configured on the vlan interface.
  • The same network configuration worked previously during the discovery phase.
  • If rd.break is used to access the system, and the network configuration is manually defined, the ignition is pulled properly and the installation completes successfully.

Environment

  • Red Hat OpenShift Container Platform (RHOCP)
    • Assisted Installer or ISO methods
    • Consistently reproduced the issue in version 4.12
    • The issue does not occur in version 4.13 or later
