Symptoms

用户正在执行“网络链路中断验证测试”。用户恢复网络连接访问后,除一个 Red Had Enterprise Linux 客户端外,其他所有 NFS 客户端都可以恢复对 Unity NFS 共享的 NFS 访问。

 

在 Unity 和 Red Had Enterprise Linux 客户端之间同时执行的网络跟踪显示,Red Had Enterprise Linux 客户端尝试使用 NFSv4.2 装载 Unity NFS 共享。

NFS V4 Call (Reply In 13) EXCHANGE_ID
NFS V4 Reply (Call In 12) Status: NFS4ERR_MINOR_VERS_MISMATCH

 

Cause

跟踪捕获了 NFSv4 客户端发出次要版本为“2”的EXCHANGE_ID请求,该请求收到 Unity 响应 NFS4ERR_MINOR_VERS_MISMATCH (10021),指示 Unity 不支持此次要版本。

 

Resolution

NFS4ERR_MINOR_VERS_MISMATCH (10021) 响应后,NFSv4 客户端有责任将次要版本从“2”回退到“1”或“0”(或使用 NFSv3)。

建议对 NFSv4 主机执行“重新启动”。然后,主机会尝试与支持的次要版本协商。
