我用：
我用ocfs文件系统生成镜像文件如下：
ocrconfig -replace ocrmirror /ocfs/clusterware/ocr1
[root@rac2 clusterware]# ll
total 404212
-rw-r-----1 oracle oinstall 4165632 Feb 13 15:58 ocr
-rw-r--r--1 oracle oinstall 399507456 Feb 13 16:56 ocr1
1、生成的镜像很大，为什么？
然后
[root@rac2 clusterware]# ocrcheck
Status of Oracle Cluster Registry is as follows :

[root@rac2 clusterware]# ocrconfig -replace ocr
[root@rac2 clusterware]# ocrcheck
