Hello, I have the following problem. Occasionally, the backup keepalived instance becomes master, brings up the virtual IPs, but then it fails bringing them down after it realizes that another instance with higher prio number is online.
Here are excerpts from the log files. everything happens within a second so timestamps are omitted. On the backup server: Keepalived_vrrp: VRRP_Instance(INTIF) Transition to MASTER STATE Keepalived_vrrp: VRRP_Group(VG1) Syncing instances to MASTER state Keepalived_vrrp: VRRP_Instance(EXTIF) Transition to MASTER STATE Keepalived_vrrp: VRRP_Instance(EXTIF) Entering MASTER STATE Keepalived_vrrp: VRRP_Instance(INTIF) Received higher prio advert Keepalived_vrrp: VRRP_Instance(INTIF) IPSEC-AH : Syncing seq_num - Decrement seq Keepalived_vrrp: VRRP_Instance(INTIF) Entering BACKUP STATE Keepalived_vrrp: VRRP_Group(VG1) Syncing instances to BACKUP state kernel: [31833.448553] IPVS: stopping backup sync thread 2564 ... kernel: [31833.451613] IPVS: stopping master sync thread 2587 ... On the master: Keepalived_vrrp: VRRP_Instance(EXTIF) Received lower prio advert, forcing new election Keepalived_vrrp: VRRP_Instance(EXTIF) IPSEC-AH : Syncing seq_num - Increment seq Keepalived_vrrp: VRRP_Instance(INTIF) Received lower prio advert, forcing new election Keepalived_vrrp: VRRP_Instance(INTIF) IPSEC-AH : Syncing seq_num - Increment seq Keepalived_vrrp: VRRP_Instance(EXTIF) Received lower prio advert, forcing new election Keepalived_vrrp: VRRP_Instance(EXTIF) IPSEC-AH : Syncing seq_num - Increment seq INTIF and EXTIF are two vrrp instances associated with different interfaces of the load balancer VG1 is a vrrp_sync_group containing both INTIF and EXTIF vrrp instances. auth_type is AH advert_int is 1 In the case above, the VIPs associated with the EXTIF instance remained up regardless that it was logged that the VG1 instances are syncing to backup state. In other cases, the VIPs on both EXTIF and INTIF will remain up. The environment is: OS: Ubuntu 12.04.3 LTS kernel: 3.2.0-54-generic keepalived: 1.2.2-3ubuntu1.1 ipvsadm: 1.25.clean-1ubuntu5 Any idea what may be causing this?
