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)

디스크 파티션 생성

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').

[root@rac1 ~]# ls /dev/sd*
/dev/sda  /dev/sda1  /dev/sda2  /dev/sdb  /dev/sdb1  /dev/sdb2

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

디스크 파티션 확인

fdisk -l /dev/sdb

[root@rac1 ~]# fdisk -l /dev/sdb
