dmesg가 출력할 수 있는 메세지 종류 - hard resetting link

이 메시지는 주로 SATA 연결에 문제가 있을 때 나타납니다.

 

SATA 케이블이란?

SATA(시리얼 ATA)는 컴퓨터의 저장 장치와 메인보드를 연결하는 표준 인터페이스입니다. 기존의 병렬 ATA(PATA)보다 빠른 데이터 전송 속도를 제공하며, 더 얇고 유연한 케이블을 사용하여 컴퓨터 내부의 공간 활용도를 높입니다. SATA는 데이터를 직렬 방식으로 전송하기 때문에 더 효율적이며, 현재 대부분의 하드 드라이브와 SSD에서 사용되고 있습니다. 이 이미지는 SATA 케이블이 디스크와 메인 보드를 연결한 사례입니다.

이 에러가 나타나는 경우는 SATA 케이블 자체 문제, 드라이브 식별 실패, SATA 링크 속도 설정 등등 여러 경우에서 에러가 발생할 수 있습니다.

 

예시:
ata2.00: exception Emask 0x0 SAct 0x2 SErr 0x0 action 0x6 frozen

ata2.00: cmd 60/48:08:6f:13:3a/00:00:01:00:00/40 tag 1 ncq 36864 in

ata2.00: status: { DRDY }

ata2: hard resetting link

ata2: SATA link up 3.0 Gbps (SStatus 123 SControl 300)

ata2.00: configured for UDMA/133

ata2: EH complete

ATA (Advanced Technology Attachment)

ATA는 스토리지 장치를 컴퓨터 시스템에 연결하기 위한 표준 인터페이스입니다.

이 로그 메시지는 ATA 장치(일반적으로 하드 드라이브나 SSD)와의 통신 문제를 나타냅니다. 특히, 장치가 명령을 완료하지 못하고 타임아웃(timeout)이 발생하여 시스템이 해당 SATA 링크를 재설정하려고 시도한 상황을 보여줍니다. 문제 해결을 위해 구체적이고 단계별로 접근하는 것이 중요합니다.

 

DRDY ERR:

DRDY는 Device Ready의 약자로, 하드웨어 장치가 데이터 전송을 위해 준비되었음을 나타내는 신호입니다

이 메시지는 주로 디스크 읽기/쓰기 작업 중에 문제가 발생했음을 나타냅니다.

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.
