例如：10.10.19.12:/ /local/test nfs vers=4,minorversion=0,hard,timeo=600,retrans=2,_netdev,noresvport 0 0

使用 NFS3.0 挂载
<挂载点IP>:/<fsid> <待挂载目标目录> nfs vers=3,nolock,proto=tcp,hard,timeo=600,retrans=2,_netdev,noresvport 0 0
例如：10.10.19.12:/djoajeo4 /local/test nfs vers=3,nolock,proto=tcp,hard,timeo=600,retrans=2,_netdev,noresvport 0 0

使用 Turbo 挂载
