1.如果使用命令mount -t nfs 192.168.1.101:/opt/FriendlyARM/mini2440/root_nfs /mnt/root_nfs，则会有如下的错误提示（也就是省去了"-o nolock"）： # mount -t nfs 192.168.1.101:/opt/FriendlyARM/mini2440/root_nfs /mnt/root_nfs portmap: server localhost not responding, timed out RPC: failed to contact portmap (errno -5). portmap: server localhost not responding, timed out RPC: failed to contact portmap (errno -5). lockd_up: makesock failed, error=-5 portmap: server localhost not responding, timed out RPC: failed to contact portmap (errno -5).
