oracle11g RAC 啟動時無法識別ASM
環境:RHEL5.5 + oracle11g RAC
客戶聯絡說關閉cluster後,重啟啟動,發現CRS無法啟動。提示Cannot communicate with Cluster Ready Services。
登入主機檢查

從錯誤資訊判斷是ASM出現了問題,檢查ASM磁碟
[root@rac-2 ~]# /etc/init.d/oracleasm listdisks
ASMDATA01
ASMDATA02
ASMDATA03
OCR_VOTE
磁碟是存在的。
關閉CRS後,檢查CRS相關程式

CRS已經關閉,但是好多程式沒有釋放。手動kill掉這些程式
[root@rac-2 ~]# ps -ef | grep d.bin | awk '{print $2}' | xargs kill -9
kill 23131: No such process
