keepalived doesn't detect loss of virtual IP

We experienced this issue and decided it is an issue with systemd-networkd in ubuntu 18.04 now using netplan. A newer version of keepalived should fix this as it can detect the removal of the floating IP which causes a failover, see https://github.com/acassen/keepalived/issues/836.

The newer version of keepalived is not available in 18.04, and rather than trying to backport we decided to stay on ubuntu 16.04 and wait until ubuntu 20.04 for our servers that use keepalived.


This issue is fixed in keepalived 2.0.0 from 2018-05-26, see changelog of keepalived

  • Monitor VIP/eVIP deletion and transition to backup if a VIP/eVIP is removed unloes it is configured with the no-track option.
