linux nfs会崩溃么,Linux系统NFS故障现象

一、故障

故障：clnt_create: RPC: Port mapper failure - Unable to receive: errno 111 (Connection refused)

原因：NFS服务端RPC服务没有启动，需要将RPC服务启动

故障：clnt_create: RPC: Program not registered

原因：NFS服务先启动，RPC后启动，需要将NFS服务重新启动

故障：clnt_create: RPC: Port mapper failure - Unable to receive: errno 113 (No route to host)

原因：NFS服务端，防火墙拦截

二、NFS状态信息
