Full HA(Ceph) keepalive error on loadbalancer

[Shweta P]

While deploying Full HA (without swift) the parameter swift_storage_interface is by default set to eth0.222 in the user.common.yaml which is not changed, since the deployment uses ceph and not swift.

But due to this the /etc/keepalived/keepalived.conf in the loadbalancer has the following entry
vrrp_instance 51 {
  virtual_router_id 51

  # Advert interval
  advert_int 1

  # for electing MASTER, highest priority wins.
  priority 101
  state MASTER

  interface eth1

  virtual_ipaddress {
      192.168.242.41 dev eth0.222
  }

The loadbalancer does not have the interface eth0.222 created by default and does not need it for a full ha ceph deployment. So it reports an error

Even the controller vip is not associated with any interface.

Workaround change the swift_storage_interface in user.common.yaml to an interface that is present in the loadbalancer(eg eth1)

[Nagaraju-Bingi (nagaraju-bingi)]

Change the swift_storage_interface parameter value from eth0.222 to eth0 in user.common.yaml.

[Chris Ricker (chris-ricker)]

changing swift_storage_interface to a present interface is a workaround for now

right fix is not to enable the swift proxy when not using swift

[Chris Ricker (chris-ricker)]

priority set to low for now since configuration to avoid is pretty straightforward
