*** kernel source install ***
1. kernel source (kernel-2.6.18-128.el5.src.rpm) download
2. kernel-2.6.18-128.el5.src.rpm install
-> /usr/src/redhat/SPEC/kernel-2.6.spec 설치됨
3. /usr/src/redhat/SPEC/kernel-2.6.spec 파일을 vi 편집기로 연다
4. %clean을 찾아서 rm -rf $RPM_BUILD_ROOT 주석처리 (xfs source를 얻기위함)
5. #rpmbuild -bb kernel-2.6.spec : 컴파일 (unifdef 패키지 설치되어있어야 함)
-> 설치 중간에 "Not enough random bytes available. Please do some other work to give
the OS a chance to collect more entrop!" 라는 메세지가 뜰 경우, 다른 창에서
#rngd -r /dev/urandom 실행하면 설치 계속됨
6. #cd /usr/src/redhat/BUILD/kernel-2.6.18/linux--2.6.18.x86-64/
7. #make mrproper : 커널환경삭제
8. /boot/config-2.6.18-128.el5 파일을 .config 로 복사
9. make oldconfig
10. .config파일을 vi 편집기로 열어서 XFS 부분 수정
#CONFIG_XFS_FS is not set
->주석 빼고 CONFIG_XFS_FS=m
* m : module file 생성, y : kermodule에 삽입
11. mkdir .tmp_versions
(* 만들어주지 않을 경우 컴파일하는 중간에 .tmp_version 디렉토리 생성하라는 메세지 출력)
12. make fs/xfs/xfs.ko
13. cd /usr/src/redhat/BUILD/kernels/linux-2.6.8-128.el5-x86_64/fs/xfs xfs 생성 확인
(#ls -ltr)
14. cd /usr/src/redhatBUILD/kernels/linux-2.6.8-128.el5-x86_64 /fs/xfs
15. insmod xfs.ko
16. lsmod 로 확인
17. cp xfs.ko /lib/modules/2.6.18-128.el5/kernel/fs/
18. cd /lib/modules/2.6.18-128.el5
19. depmod -a
( * depmod : module.dep 파일생성)
20. modprobe로 올릴 수 있다.
(modprobe -r xfs : xfs 모듈 삭제)
21. xfs로 filesystem 구성
