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

1)
[root@nfs_server ~]# cat /var/lib/nfs/rmtab 
192.168.1.114:/data:0x00000001
2)
[root@nfs_server ~]# cat /var/lib/nfs/etab
