执行cls_cleanup检查是否可以修复
对照下面的代码，看下日志（/var/log/cluster/corosync.log）里输出什么错误消息:

https://github.com/ChenHuajun/pha4pgsql/blob/master/ra/lvsdr

lvsdr_monitor() {

    # check virtual server for ${OCF_RESKEY_vip}:${OCF_RESKEY_port} 
    ipvsadm -L -t ${OCF_RESKEY_vip}:${OCF_RESKEY_port} >/dev/null 2>&1
    if [ $? -ne 0  ]; then
        if ocf_is_probe; then
            ocf_log info "These is no virtual service definition for this virtual servie"
        else
            ocf_log err "These is no virtual service definition for this virtual servie"
        fi
        return $OCF_NOT_RUNNING
    fi

    #update Real Servers 
    update_lvs
    if [ $? -ne 0 ]; then
       return $OCF_ERR_GENERIC
    fi
    return $OCF_SUCCESS
}

可以手动执行下面启动LVS的命令，看哪一步失败

lvsdr_start() {
#lvsdr_monitor
#if [ $? =  $OCF_SUCCESS ]; then
#    return $OCF_SUCCESS
#fi

# Since this is the Director we must be able to forward packets
echo 1 > /proc/sys/net/ipv4/ip_forward
echo 1 > /proc/sys/net/ipv4/vs/expire_nodest_conn

# Clear all iptables rules.
#iptables -F
# Reset iptables counters.
#iptables -Z
# Clear all ipvsadm rules/services.
#ipvsadm -C
ipvsadm -D -t ${OCF_RESKEY_vip}:${OCF_RESKEY_port} 2>/dev/null

# Add an IP virtual service for VIP ${OCF_RESKEY_vip}:${OCF_RESKEY_port}
ipvsadm -A -t ${OCF_RESKEY_vip}:${OCF_RESKEY_port} ${OCF_RESKEY_virtual_service_options}
if [ $? -ne 0 ]; then
    ocf_exit_reason "fail to add virtual server via ipvsadm"
    return $OCF_ERR_GENERIC
fi
}
