redhat AS 4用RHCS做HA，斷掉第一台機器網線，服務不能切換！
兩台機器系統Redhat AS 4 U4
集群軟體 RHCS
兩台機器相關的配置如下：
# more /etc/hosts 兩台機器一樣的內容
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost
192.168.0.201 vm001
192.168.0.202 vm002
兩台機器正常啟動之後
#clustat -i 3
Member Status: Quorate
Member Name Status
------ ---- ------
vm001 Online, rgmanager
vm002 Online, Local, rgmanager
Service Name Owner (Last) State
------- ---- ----- ------ -----
ftpservice vm001 started
但是我斷掉第一根網線之後，等了1分鐘之後，出現
#clustat -i 3
Member Status: Quorate
Member Name Status
------ ---- ------
vm001 Offline
vm002 Online, Local, rgmanager
Service Name Owner (Last) State
------- ---- ----- ------ -----
ftpservice unknown started
我的集群配置文件是：
# more /etc/cluster/cluster.conf
<?xml version="1.0" ?>

請問有什麼辦法，解決網線斷了，在備機起服務？(首先我這兩台機器服務可以相互切換)

學習
我這裡也正準備弄個集群,可不可以把安裝文檔共享一下???
非常感謝!
《解決方案》
rh-cs-en-4.pdf，網上有的下載的！
《解決方案》
vsftpdHA.sh =
/var/log/messages =
ifconfig -a =
另外從4.4開始又加回了3里的仲裁分區
《解決方案》
我也做的兩個機器，我把其中一個機器的rgmanager停掉，整個cluster都down掉了，感覺這玩意可以對其上的服務提供高可用性，其本身沒有啥高可用性
《解決方案》
我想知道樓主配置的雙機的硬體設備都有什麼？？
兩台主機＋共享磁碟＋powerswitch＋雙機軟體？
《解決方案》
裝的系統是Redhat AS 4
雙機軟體是rhel-4-u4-rhcs-i386-disc1.iso
沒有powerswitch，機器是雙網卡，第二個網卡做心跳。
共享磁碟是dell cx300
就是弄不清楚，RHCS為什麼不能實現網線斷的切換，一直很納悶，為什麼會這樣了？
《解決方案》
仔細看一下/var/log/messages文件，你會找到答案的

正常的情況
# clustat -i 3
Member Status: Quorate
Member Name Status
------ ---- ------
vm001 Online, rgmanager
vm002 Online, Local, rgmanager
Service Name Owner (Last) State
------- ---- ----- ------ -----
ftpservice vm001 started
斷掉第一塊網卡的連接
# clustat -i 3
Member Status: Quorate
Member Name Status
------ ---- ------
vm001 Offline
vm002 Online, Local, rgmanager
Service Name Owner (Last) State
------- ---- ----- ------ -----
ftpservice unknown started
一直是這樣，切換不過去！

仔細看看紅色的部分吧
