1. 디스크 파티션 작업
| 파티션명 | 파티션 크기 | 용도 |
|---|---|---|
| /dev/sdb1 | 15G | Raw Device 영역으로 세부 분할하여 사용 |
| /dev/sdb2 | 5G | OCFS2 영역으로 할당하여 Fast Recovery Area로 사용 (OCFS2를 이용한 공유 영역) |
A) 디스크 파티션 생성
root 유저로 수행
fdisk /dev/sdb
[root@rac1 ~]# ls /dev/sd*
/dev/sda /dev/sda1 /dev/sda2 /dev/sdb
[root@rac1 ~]# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x71c49a77.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
switch off the mode (command 'c') and change display units to
sectors (command 'u').

fdisk 명령어로 Raw Device로 사용할 디스크의 파티션을 생성합니다.
각 프롬프트에서 n → p → 1 → "엔터(기본값 1)" → "+15G" → n → p → 2 → "엔터(기본값 1960)" → "엔터(기본값 2610)" → p → w 를 입력하여 파티션 분할
B) 디스크 파티션 확인

fdisk -l /dev/sdb

쉘에서 수행할 경우 서버를 재부팅하게 되면 초기화되므로 /etc/rc.d/rc.local에 등록합니다.
H) Raw Device 소유자, 그룹 및 권한 정의
root 유저로 vi /etc/udev/rules.d/60-raw.rules 추가
ACTION=="add", KERNEL=="raw*", OWNER=="grid", GROUP=="dba", MODE=="0660" #ACTION=="add", KERNEL=="raw*", OWNER=="oracle", GROUP=="dba", MODE=="0660"
Raw Device 의 소유자, 그룹 및 권한 설정이 재부팅시에도 적용될 수 있도록 rules에 추가합니다.
{"enableNumbering":true}
3. FRA 영역을 위한 OCFS2 설정
A) OCFS2 설치를 위한 Linux Local Yum 설정
외부 인터넷 연결을 하지않고 설치 ISO 이미지로 YUM Repository를 구성하여 yum install을 사용할 수 있도록 설정하는 방법입니다.
디스크 마운트
mount /dev/cdrom /mnt df | grep mnt
[root@ol6 ~]# mount /dev/cdrom /mnt mount: block device /dev/sr0 is write-protected, mounting read-only [root@ol6 ~]# df | grep mnt Filesystem 1K-blocks Used Available Use% Mounted on /dev/sr0 3976444 3976444 0 100% /mnt
VM에 ISO 파일을 연결하고, cdrom을 디렉토리에 mount 시켜줍니다.
기존 Repository 파일 정리
mv /etc/yum.repos.d/public-yum-ol6.repo /etc/yum.repos.d/public-yum-ol6.repo.bak
[root@ol6 ~]# mv /etc/yum.repos.d/public-yum-ol6.repo /etc/yum.repos.d/public-yum-ol6.repo.bak
기존에 생성되어 있던 Repository 파일은 모두 이름을 변경하여, 사용하지 않도록 수정합니다.
vi /etc/yum.repos.d/local.repo
[ol6] name=ol6 baseurl=file:///mnt/ enabled=1 gpgcheck=0
[root@ol6 ~]# cat /etc/yum.repos.d/local.repo [ol6] name=ol6 baseurl=file:///mnt/ enabled=1 gpgcheck=0
local.repo라는 Repository 파일을 생성합니다.
Repository 이름과 연결될 디렉토리 등을 입력합니다.
Repository 로딩 및 확인
