-> 삭제하면 물리적 화일은 정보만 업데이트 되고 그냥 남아 있음.
2) 다음은 ocr disk 테스트
1. 그냥 add 하면 아래와 같이 에러발생함.
[root@ocfs1:/root]# ocrconfig -add /vote04/ocr04
PROT-30: The Oracle Cluster Registry location to be added is not usable.
PROC-50: The Oracle Cluster Registry location to be added is inaccessible on nodes ocfs1.
2. touch /vote04/ocr04
chown root:dba /vote04/ocr04
[root@ocfs1:/root]# ocrconfig -add /vote04/ocr04
[root@ocfs1:/root]# ocrcheck
Status of Oracle Cluster Registry is as follows :
Version : 4
Total space (kbytes) : 491684
Used space (kbytes) : 84036
Available space (kbytes) : 407648

3. delete 및 replace 테스트

- replace 진행
[root@ocfs1:/root]# ocrconfig -replace /vote03/ocr03 -replacement /vote04/ocr04
[root@ocfs1:/root]# ocrcheck
Status of Oracle Cluster Registry is as follows :
Version : 4

물리적인 화일은 남아있어서 수동으로 삭제 필요
[root@ocfs1:/vote04]# ls -al

결론 :
CFS 환경에서 ocr/voting add 작업시에는
1) voting 은 주어진 이름으로 바로 생성되고
2) ocr file 은 touch 로 미리 화일 생성이 되어 있어야 정상 작업이 가능하다
3) replace 도 정상적으로 잘됨.
