heartbeat+DRBD 自動(dòng)切換出現(xiàn)問(wèn)題

heidern

兩臺(tái)VMware服務(wù)器：
1、Centos-1 192.168.48.10
2、Centos-2 192.168.48.20
drbd配置沒(méi)問(wèn)題，heartbeat配置好以后隨便手動(dòng)關(guān)閉某一臺(tái)的heartbeat都可以切換到對(duì)方，但今天在Centos-1上做如下實(shí)驗(yàn)：
[root@Centos-1 ~]# iptables -A INPUT -j DROP
本以為Centos-2偵測(cè)不到Centos-1的心跳會(huì)將自己提升為Active，但結(jié)果Centos-02的日志出乎意料：


heartbeat[11228]: 2010/02/25_11:51:47 ERROR: Both machines own our resources!
heartbeat[11228]: 2010/02/25_11:51:47 ERROR: Both machines own our resources!
heartbeat[11228]: 2010/02/25_11:59:52 info: all clients are now paused
heartbeat[11228]: 2010/02/25_12:03:58 WARN: Message hist queue is filling up (376 messages in queue)
heartbeat[11228]: 2010/02/25_12:04:00 WARN: Message hist queue is filling up (377 messages in queue)
heartbeat[11228]: 2010/02/25_12:04:02 WARN: Message hist queue is filling up (378 messages in queue)

而且DRBD也出現(xiàn)了問(wèn)題：當(dāng)iptables規(guī)則生效后，Centos-2上的DRBD狀態(tài)是：
version: 8.3.2 (api:88/proto:86-90)
GIT-hash: dd7985327f146f33b86d4bff5ca8c94234ce840e build by mockbuild@v20z-x86-64.home.local, 2009-08-29 14:07:55

1: cs:StandAlone ro:Secondary/Unknown ds:UpToDate/DUnknown   r----
    ns:0 nr:0 dw:0 dr:0 al:0 bm:0 lo:0 pe:0 ua:0 ap:0 ep:1 wo:b oos:4
也就是說(shuō)看不到Centos-2的狀態(tài)了（這個(gè)應(yīng)該沒(méi)有問(wèn)題）
把Centos-1的iptables去掉后，狀態(tài)沒(méi)有恢復(fù)，重啟兩臺(tái)機(jī)器的DRBD和heartbeat后，兩臺(tái)機(jī)器的DRBD狀態(tài)都變成了version: 8.3.2 (api:88/proto:86-90)
GIT-hash: dd7985327f146f33b86d4bff5ca8c94234ce840e build by mockbuild@v20z-x86-64.home.local, 2009-08-29 14:07:55

1: cs:StandAlone ro:Secondary/Unknown ds:UpToDate/DUnknown   r----
    ns:0 nr:0 dw:0 dr:0 al:0 bm:0 lo:0 pe:0 ua:0 ap:0 ep:1 wo:b oos:4

這到底是為什么呢？怎么解決��？高手指點(diǎn)下，謝謝！

附配置文件(兩臺(tái)都一樣）
[root@Centos-2 resource.d]# cat /etc/ha.d/ha.cf|grep -v \#
logfile /var/log/ha-log
keepalive 2
deadtime 10
warntime 5
udpport 694
auto_failback on
node    Centos-1 Centos-2
[root@Centos-2 resource.d]# cat /etc/ha.d/haresources|grep -v \#   
Centos-1 192.168.48.60 drbddisk::r0 Filesystem::/dev/drbd1::/mnt/drbd1::ext3

沒(méi)人知道怎么回事嗎。。

    DROP了雙側(cè)的通信 當(dāng)然會(huì)產(chǎn)生混亂了 兩側(cè)都在認(rèn)為對(duì)方已經(jīng)down了

那這種情況如何修復(fù)呢？
