keepalived + lvs 172.16.30.31 master 172.16.30.32 backup 172.16.30.10 vip 故障:监控显示keepalived master主机故障;通过ping查看vip存在。master重启以后,VIP漂移回master. 偶然间,重启master网卡发现,vip漂移backup以后,无法漂移回master;需重启master-keealived服务,VIP才可漂移回master. master: message May 9 10:47:06 sd3031 Keepalived_healthcheckers[31967]: Netlink reflector reports IP 172.16.30.31 removed May 9 10:47:06 sd3031 Keepalived_vrrp[31968]: Netlink reflector reports IP 172.16.30.31 removed May 9 10:47:06 sd3031 Keepalived_vrrp[31968]: Netlink reflector reports IP 172.16.30.10 removed May 9 10:47:06 sd3031 Keepalived_healthcheckers[31967]: Netlink reflector reports IP 172.16.30.10 removed May 9 10:47:06 sd3031 avahi-daemon[3924]: Withdrawing address record for 172.16.30.31 on eth0.
