FreeNAS(9.10-STABLE-201605240427) 서버와 여러 CentOS 6.4 시스템이 있습니다. 그러나 CentOS 시스템은 CIFS 또는 NFS(3 및 4)를 사용하여 마운트되었는지 여부에 관계없이 4KB보다 큰 파일에 대해 FreeNAS 마운트에 쓸 수 없는 것 같습니다.
이상한 이유로 4KB(페이지 크기)보다 큰 파일에 쓰려고 할 때마다 일종의 교착 상태가 발생하는 것 같습니다.
이것은 /bin/ls를 마운트에 복사하려고 할 때 CentOS 시스템의 NFS 디버그 로그에서 발췌한 것입니다.

나는 이 문제의 원인이 무엇인지 전혀 모릅니다. Windows 및 OS X 클라이언트 모두 문제 없이 이러한 파티션을 마운트하고 읽고 쓸 수 있습니다. 이러한 장치는 동일한 스위치에 직접 연결되며 VLAN 태그/가상 인터페이스 외에는 네트워크에 장애가 발생할 이유가 없습니다.
Ubuntu 컴퓨터에서 문제를 재현할 수 있었기 때문에 FreeNAS 서버 자체에 결함이 있다고 생각했지만 다시 설치해도 문제가 해결되지 않았습니다.
답변1
그것을 해결했습니다.
FreeNAS의 기본 MTU 설정은 9000이며, 네트워크 카드는 이 설정을 지원하지 않습니다. 따라서 많은 패킷이 삭제되어 중단이 발생할 수 있습니다.
해결 방법은 네트워크 인터페이스 설정에 "mtu 1400"을 추가하는 것입니다.
이것은 네트워크 문제입니다. 이것이 같은 위치에 있는 누군가에게 도움이 되기를 바랍니다.
