AsM丟魂記？（三）

今天我的朋友告訴我，儲存已經修好了。磁碟卷也找到了。讓我啟動一下資料庫的RAC。我滿懷信心的啟動資料庫，結果發現問題依舊。還是沒有找到ASM卷。難道是磁碟沒有掛載上？

的確比前天多找到一個219G的磁碟，但是肯定不是存放ASM資料的卷。我查詢過ASM存資料的磁碟有1個T。

那這個盤究竟是做什麼用的呢？

mount /dev/sdh1 /tmp

[root@rac2 tmp]# cd /tmp
[root@rac2 tmp]# ls
expdata exportcmd lost+found
[root@rac2 tmp]# cd expdata
[root@rac2 expdata]# ls
exportcmd.bk.dhm      FMIS_0002db01.dmp     fmis0014dbexport.log
exportcmd.dhm         fmis0002dbexport.log FMIS_0015db01.dmp
exportcmd.fmis0001    FMIS_0013db01.dmp     fmis0015dbexport.log
FMIS_0001db01.dmp     fmis0013dbexport.log FMIS_0016db01.dmp
fmis0001dbexport.log FMIS_0014db01.dmp     fmis0016dbexport.log
顯然是以前EXP匯出檔案，看來不是我要的ASM卷。

值得我憂慮的是:在/etc/fstab中並沒有看到這個磁碟：

我的理解是ASM對這個磁碟進行直接掛載，不需要寫到磁碟啟動項中。會是這樣嗎？

等找到這個磁碟就有答案了。
