在安裝RAC 時，出了不少問題。
現匯總如下：
1、開始安裝時，因兩節點同時運行了root.sh，以至出錯， ohasd 不能啟動。
後來刪除重新安裝，先前建立的CRS 磁碟組已不能選擇了。只好再退出來，（選擇已是磁碟成員）
（後面經查詢資料才知，可以在刪除檔案前，執行ASMCA進行管理ASM磁碟組）
先刪除CRS對應的3個磁碟 CRS1,CRS2,CRS3, 再使用 Oracleasm createdisk 重建立立。
再進入安裝介面，可以選擇此3個磁碟進行建立磁碟組CRS 了。
2.提示：ADVM/ACFS is not supported on CentOS-release-5-5.el5.centos
不知是否會有後遺症，但暫時沒出錯。
3.最後執行root.sh 完後，安裝步驟走到最後一步，又出： [INS-20802] Oracle Cluster Verification Utility failed
錯誤。
這裡暫時沒有其它更好的解決辦法，只好跳過去。安裝ORACLE 資料庫，並建立一個資料庫(DBCA)
有的人說是： 原來就是節點一致性上做的有問題 ，但我的檢查，全部通過。
