After installation using bonding configuration with OVNkubernets plugin system crashed on baremetal cluster

Solution In Progress - Updated -

Issue

  • After booting up coreos master nodes using kernel cmd line parameters [1], it initiates and the session is started. Both the nics along with the bond0 nw interface come up. The IP gives response to pings and the machine can be ssh-ed [2].

  • After sometime, the session terminates abruptly and the ip does not give a response to ping. From the vm console, it shows nothing. After rebooting the machine it shows the error where it states the network interfaces are not ready.

  • [1] Kernel cmd :
    ip=:::::bond0:none nameserver= bond=bond0:,:mode=active-backup.

  • [2] After master0 booted up, we were able to login and check bonded interface. After sometime the connection got automatically closed.
