lvs+heartbeat主备切换问题?

tech_linux

目前配置lvs+heartbeat+ldir+ldirectord. 现在遇到问题主lvs down掉网卡后. 备lvs无法接管vip, vip就不通了.

ha.cf配置:
#debugfile /var/log/ha-debug
logfile /var/log/ha-log
logfacility     local0
keepalive 1
deadtime 10
warntime 10
initdead 15
udpport 694

bcast   eth0                        # Linux
ucast   eth0 10.10.10.4     # 主lvs（10.10.10.3） , 备lvs（10.10.10.4），VIP：10.10.10.2
auto_failback on

node    test01
node    test02

ping 10.10.10.1      #网关
