이 메시지를 이해하기 위해선 몇 가지의 용어 뜻을 알고 있어야 합니다.

 

DMA (Direct Memory Access)

DMA는 디바이스가 CPU의 개입 없이 직접 메모리에 접근할 수 있도록 하는 기술입니다. 이를 통해 데이터를 더 빠르게 전송할 수 있으며, CPU의 부하를 줄일 수 있습니다.

 

IDNF (Identifier Not Found): 요청된 데이터 블록이나 섹터를 디스크 상에서 찾을 수 없을 때 발생하는 오류 코드입니다.

 

UDMA (Ultra DMA): DMA 전송 모드의 한 형태로, 데이터 전송 속도를 향상시키는 기술입니다. UDMA/133은 초당 133MB의 데이터 전송 속도를 지원합니다.

 

Emask (Error Mask): 발생한 오류의 유형이나 성격을 나타내는 코드입니다. 예를 들어, 'invalid argument'는 전달된 명령이나 파라미터가 잘못되었음을 나타냅니다.

 

IRQ (Interrupt Request): 하드웨어 장치가 CPU의 주의를 요청할 때 사용하는 신호 또는 번호입니다. IRQ 상태는 장치가 시스템에 어떤 중단 요청을 보냈는지 나타냅니다.

 

EH (Error Handling): 시스템이 오류를 감지하고 처리하는 메커니즘입니다. 'EH complete'는 오류 처리 절차가 완료되었음을 나타냅니다.

 

CDB (Command Descriptor Block): SCSI(스몰 컴퓨터 시스템 인터페이스) 장치에 전송되는 명령 세트입니다. ATA 장치에서도 비슷한 개념이 사용되며, 장치에 수행할 작업을 알립니다.

 

Logical block address (LBA): 디스크 상의 데이터 블록 위치를 지정하는 방법입니다. 'Logical block address out of range' 오류는 요청된 블록 주소가 디스크의 범위를 벗어났음을 의미합니다.

 

로그 메시지 분석을 통해 확인할 수 있는 주요 문제는 하드 드라이브 또는 SSD와의 통신 문제, 특히 "WRITE DMA EXT" 명령 실행 중 "IDNF (Identifier Not Found)" 오류가 발생한 것입니다. 이 오류는 시스템이 디스크 상의 특정 블록에 액세스하려고 시도했지만 해당 블록을 찾을 수 없음을 나타냅니다. 일반적으로 이는 물리적 또는 논리적 디스크 손상과 관련이 있습니다.

 

해결방안은 smartctl, 파일시스템 검사, 디스크 포맷, sata 케이블 연결 확인, 디스크 교체가 있겠습니다.
