查看 NFS 的活动网络连接
您可以使用以下命令验证是否与 SVM 建立了多个 TCP 连接： network connections active show 命令。
例如，如果要查看 NFS 会话中继，请查找来自同一客户端在每个节点的不同接口上的连接：
cluster::*> network connections active show -node cluster-0* -vserver PNFS

查看已连接客户端的 NFS 版本信息
您还可以使用以下方式查看 NFS 连接： nfs connected-clients show 命令。请注意，此处显示的客户列表是过去 48 小时内有活跃 NFS 流量的客户。空闲的 NFS 客户端（即使仍然挂载）可能要等到访问挂载点时才会显示出来。您可以通过指定以下参数来筛选这些客户端，使其仅显示最近访问过的客户端： -idle-time 特征。
例如，要查看过去 10 分钟内 pNFS SVM 中有活动的客户：
cluster::*> nfs connected-clients show -vserver PNFS -idle-time <10m> Node: node-01 Vserver: PNFS Data-Ip: 10.x.x.x Local Remote Client-Ip Protocol Volume Policy Idle-Time Reqs Reqs Trunking 10.x.x.a nfs4.2 PNFS_root default 9m 10s 0 149 false 10.x.x.a nfs4.2 FG_0001 default 9m 10s 135847 0 false 10.x.x.b nfs4.2 PNFS_root default 8m 12s 0 157 false 10.x.x.b nfs4.2 FG_0001 default 8m 12s 52111 0 false
