Description Yossi Boaron 2021-01-26 20:33:24 UTC

Description of problem:

When Keepalived container that holds VIP being SIGTERMed (for example , as a result of 'virsh shutdown <node>' command in a virtual environment ) that should trigger a  priority 0 advertisement message  to allow faster VIP migration.

Running  'virsh shutdown <node>' command on a node holding VIP didn't trigger  VRRP priority 0 advertisement message

Version-Release number of selected component (if applicable):


How reproducible:

In dev-scripts environment
1. Check which node holds the VIP
2. run 'virsh shutdown <node> '

Steps to Reproduce:

See above

Actual results:
VIP moved to another node after timeout (3 * interval) 

Expected results:

1. Keepalived in shutdown node should send VRRP priority 0 advertisement message
2. Keepalived in one of the remaining master nodes should hold the VIP as soon as he receives the VRRP priority 0 message
