今天我的朋友告诉我，存储已经修好了。磁盘卷也找到了。让我启动一下数据库的RAC。我满怀信心的启动数据库，结果发现问题依旧。还是没有找到ASM卷。难道是磁盘没有挂载上？

的确比前天多找到一个219G的磁盘，但是肯定不是存放ASM数据的卷。我查询过ASM存数据的磁盘有1个T。

那这个盘究竟是做什么用的呢？

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
显然是以前EXP导出文件，看来不是我要的ASM卷。

值得我忧虑的是:在/etc/fstab中并没有看到这个磁盘：

我的理解是ASM对这个磁盘进行直接挂载，不需要写到磁盘启动项中。会是这样吗？

等找到这个磁盘就有答案了。
