저는 Debian 10에서 KVM을 호스트로 사용하고 있으며 현재 두 명의 게스트도 Debian 10입니다. 손님은 자주 "말더듬"합니다. 즉, 적어도 한 시간에 여러 번 손님이 10초 동안 응답하지 않는다는 의미입니다. SSH 세션이 열려 있고 입력 중이라면 게스트가 자발적으로 "고정 해제"될 때까지 아무것도 할 수 없습니다. "동결" 직전에 입력한 내용이 여전히 버퍼링되어 있는 것 같습니다. 게스트가 고정 해제되면 모든 내용이 명령줄에 나타나기 때문입니다.
호스트 상자는 그런 일을 겪지 않습니다.
호스트는 다음 구성을 사용하는 활성/수동 클러스터의 일부입니다.
- 두 개의 디스크가 RAID-1 설정에서 작동하고 있고, 두 개의 파티션이 루트 fs용으로 형성되고 , 두 개의 더 큰 파티션이 게스트 데이터용으로
/dev/md0결합됩니다 ./dev/md1 /dev/md1두 클러스터 호스트 사이의 DRBD 장치에 사용됩니다. 동기 쓰기를 위한 프로토콜 C는 호스트 간에 사용됩니다.- LVM은 DRBD 장치 위에 쌓입니다. 게스트는 디스크에 원시 LVM 볼륨을 사용합니다.
- 두 번째 호스트는 존재하지 않으며 아직 생산되지 않습니다.
올바르게 기억한다면 KVM 호스트 또는 게스트 설정에서 실제로 아무것도 변경하지 않았으며 기본값을 사용했습니다. 어쨌든 제가 가지고 있는 구성은 이렇습니다.

답변1
문제가 있는 것은 DRBD가 아니었고, 문제가 있었던 것은 호스트와 VM 캐시, IO 모드였습니다. writethroughVM 설정 및 기타 디스크(rw) 처리량을 초당 수백 킬로바이트로 분명히 감소시켰기 때문에 sync속도가 극도로 느렸습니다. . 이를 최적화한 후 문제가 사라졌습니다.

하이퍼바이저(호스트)가 메모리를 스와핑할 수 있습니다. 호스트에는 하드웨어 출력당 16GB RAM만 있습니다. *-메모리 설명: 시스템 메모리 물리적 ID: 7 슬롯: 시스템 보드 또는 마더보드 크기: 16GiB
