사람들은 느린 서버로 인해 문제를 겪고 있습니다. 작은 테이블에 쓰는 데는 5초 이상이 걸리며 이는 매우 느립니다. MySQL 데이터베이스, D3 데이터베이스 및 Linux 파일 시스템의 손상 여부를 검사했는데 오류가 보고되지 않았습니다.
Acronis SnapAPI에서 보고된 group descriptors corrupted!것 같은 상황이 발생했습니다 . dmesg저는 Acronis에 연락했으며 이 문제에 대해 답변을 기다리고 있습니다. 그들이 나에게 부패가 있는 올바른 방향을 알려줄 수 있기를 바랍니다.
또 다른 문제 dmesg는 sd 0:0:0:0: Warning! Received an indication that the operating parameters on this target have changed. The Linux SCSI layer does not automatically adjust these parameters. 이 경고가 무엇을 의미하는지 잘 모르겠습니다.
