今天重啟一個dataguad的時候,無法啟動MRP進程,報錯如下

這里說一下環境
主庫是10g 2節點RAC,備庫同樣是2個節點10g RAC,但是只有節點1做日志恢復
事故經過:
昨天由于備庫的存儲故障(有raid,數據沒異常),就停了crs讓存儲工程師維護,維護以后,新磁盤需要同步數據,所以就今天啟動dg,間隔大概24小時
今天維護好了,需要啟動,2節點分別執行了/etc/init.d/init.crs start
都知道這個命令會啟動asm及db的實例,但是我給忽略了
在節點1起來以后,看日志,數據庫open到了readonly,然后執行了shutdown,并啟動到mount執行revoer,但是這里報錯,信息如上
其實現在很清晰的能看到,1節點啟動MRP進程準備恢復,但由于2節點也處于readonly模式,數據文件已經被占用了.所以節點1的MRP沒法恢復數據文件.就被關閉了
解決辦法:
shutdown 2節點db即可
