I see you have different netmasks for the VIP on node1 vs. node2; I would also try breaking them out of the vrrp_sync_group and validating at least 1 router will fail independently.

Hi Guys, I am trying to use keepalive and haproxy to work together to improve the HA of the openstack. But I meet following unexpected issue. I expect that when the haproxy process is crashed on the MASTER node(checked by chk_haproxy), the second node will take over the VIP. But when I stop the haproxy process, nothing is happened. However, when stop the keepalived service, the VIP is set up on the node2 as expected. So I think the root cause should be the chk_haproxy block. But I have no idea why it doesn't work. Does any body have ideas? node1 keepalived.conf global_defs { lvs_id LVS_228 } vrrp_sync_group openstack_haproxy { group { v1 v2 } } vrrp_script chk_haproxy { script "killall -0 haproxy" interval 2 debug weight 2 } vrrp_instance v1 { interface eth0 debug state MASTER virtual_router_id 1 priority 101 virtual_ipaddress { 192.168.0.230/24<http://192.168.0.230/24> } track_script { chk_haproxy } } vrrp_instance v2 { interface eth1 state MASTER debug virtual_router_id 2 priority 101 virtual_ipaddress { 10.1.0.30/16<http://10.1.0.30/16> } track_script { chk_haproxy } } node2 keepalived.conf global_defs { lvs_id LVS_229 } vrrp_sync_group openstack_haproxy { group { v1 v2 } } vrrp_script chk_haproxy { script "killall -0 haproxy" interval 2 weight 2 } vrrp_instance v1 { interface eth0 state BACKUP virtual_router_id 1 priority 100 virtual_ipaddress { 192.168.0.230 } track_script { chk_haproxy } } vrrp_instance v2 { interface eth1 state BACKUP virtual_router_id 2 priority 100 virtual_ipaddress { 10.1.0.30 } track_script { chk_haproxy } } -- Lei Zhang Blog: http://jeffrey4l.github.com twitter/weibo: @jeffrey4l
