1. 공유 스토리지 생성
공유 스토리지 구성을 위해 고정 공간이 할당된 가상 디스크 6개를 추가로 생성합니다.
| 파일 이름 | 용량 | 타입 | 용도 | 비고 |
|---|---|---|---|---|
CRS1.vdi | 1GB | Fixed / Shareable | CRS 저장 영역 | 공유(shareable) 디스크로 사용하기 위해서 Fixed Size로 생성합니다. |
| CRS2.vdi | 1GB | Fixed / Shareable | ||
| CRS3.vdi | 1GB | Fixed / Shareable | ||
| DATA.vdi | 30GB | Fixed / Shareable | Data 저장 영역 | |
| FRA.vdi | 20GB | Fixed / Shareable | Fast Recovery Area | |
| RAW.vdi | 20GB | Fixed / Shareable | Raw Device 영역 |

Host 컴퓨터에서 VM에 연결시킬 공유 디스크를 생성합니다.
디스크는 2개의 노드에서 공유할 것이므로, 반드시 Fixed 모드로 디스크 공간이 사전에 할당되도록 생성해야 합니다.
B) 스토리지 파일 공유 설정
가상 디스크 타입 변경

생성된 디스크들은 모두 shareable 디스크로 속성 변경이 필요합니다.
VirtualBox의 GUI 툴을 사용하여 변경할 수도 있습니다.
C) VM에 스토리지 연결
정지된 1번 노드의 설정 모드로 들어가서 디스크 파일을 추가합니다.
SATA 콘트롤러의 오른쪽에 하드디스크 모양의 아이콘을 클릭합니다
vboxmanage 명령으로 이미 생성된 디스크 파일을 추가할 것이므로 <기존 디스크 선택하기>를 클릭합니다.
Not Attatched에 등록된 디스크 목록에서 "CRS1.vdi"를 선택한 후 <선택>을 클릭합니다.
만약 생성된 디스크 이미지가 목록에 없다면 <추가> 아이콘을 클릭한 후에 디스크 이미지를 찾아서 추가하면 됩니다.
정상적으로 스토리지가 추가된 것을 확인할 수 있습니다.
다른 공유 디스크들도 같은 방법으로 추가해줍니다.
나머지 디스크 파일 모두 순서에 맞게 SATA 컨트롤러에 등록시켜줍니다.
반드시 동일한 순서대로 다른 노드에도 등록시켜야 합니다.
2. 공유 스토리지 환경 구성

VM에 연결된 디스크에 fdisk 명령어로 파티션 분할 작업을 수행 합니다.
/dev/sdb에서부터 /dev/sdf까지는 하나의 파티션으로 분할하여 ASM 스토리지로 사용할 것입니다.
/dev/sdg 디스크는 15GB와 5GB의 파티셔으로 분할하여, 15GB는 raw device 영역으로 사용하고 나머지 5GB는 OCFS2으로 클러스터링하여 FRA 영역으로 사용합니다.
B) ASM 구성
ASM 환경 설정
oracleasm configure -i oracleasm init oracleasm status oracleasm configure
[root@rac1 ~]# oracleasm configure -i
Configuring the Oracle ASM library driver.
This will configure the on-boot properties of the Oracle ASM library
driver. The following questions will determine whether the driver is
loaded on boot and what permissions it will have. The current values
will be shown in brackets ('[]'). Hitting <ENTER> without typing an
answer will keep that current value. Ctrl-C will abort.
Default user to own the driver interface []: oracle
Default group to own the driver interface []: asmadmin
Start Oracle ASM library driver on boot (y/n) [n]: y
Scan for Oracle ASM disks on boot (y/n) [y]:
Writing Oracle ASM library driver configuration: done
[root@rac1 ~]# oracleasm init

Archive Log를 저장하기 위해서는 파일을 저장할 수 있는 공유 영역이 있어야 하며, 이를 위해서 OCFS2를 구성해야 합니다.
각각의 노드에 파일로 저장할 경우, 파일을 공유할 수 없어서 노드 장애로 인한 복구가 어려울 수 있습니다.
먼저 클러스터의 이름과 연결될 노드 정보를 저장합니다.
OCFS2 환경 설정 및 활성화

Configuring the O2CB driver.
This will configure the on-boot properties of the O2CB driver.
The following questions will determine whether the driver is loaded on
boot. The current values will be shown in brackets ('[]'). Hitting
<ENTER> without typing an answer will keep that current value. Ctrl-C
will abort.

포맷한 영역이 공유 경로에 마운트될 수 있도록 /etc/fstab에 정보를 저장합니다.
vi /etc/rc.d/rc.local 로 소유자 및 권한 설정
chown -R oracle:dba /FRA chmod -R 770 /FRA
OCFS2 영역의 소유자와 권한 부여 작업을 /etc/rc.d/rc.local에 저장하여 재기동시에 설정이 유지될 수 있도록 합니다.
부팅시 자동 수행 활성화
chmod +x /etc/rc.d/rc.local
