최근 SAN 기반 리눅스 클러스터 파일 시스템들이 개발되고 있다. 이들은 중앙 파일 서버를 두지 않으며, 디스크를 공유하는 클라이언트들이 화이버 채널을 통하여 마치 파일 서버처럼 디스크에 자유롭게 접근할 수 있다. 따라서 이 시스템들은 유용성, 부하의 균형, 확장성 등에서 장점을 가질 수 있다. 이 논문에서는 새로운 SAN 기반 리눅스 클러스터 파일 시스템을 위해 설계된 메타데이터 관리 방법들에 대하여 기술한다. 먼저, 디스크 접근 시간에서 기본의 방법보다 우수한 새로운 inode의 구조를 설명하고, 확장 해싱을 사용하는 새로운 디렉토리 구조에 대하여 기술한다. 또한, 대규모의 파일 시스템에 적합한 새로운 빈 공간 관리 방법을 제안하고, 메타데이터의 저널링 방법에 대하여 소개한다. 그리고, 성능 평가를 통하여 제안된 방법들의 우수성을 보인다.
