适用于

ONTAP 9
NFSv4

问题描述

management_lif_ip 和 client_ip 之间存在 NFS 连接

示例：

Cluster::> nfs connected-clients show -vserver svm_name

Node: node-01 Vserver: svm_name Data-Ip: management_lif_ip Client-Ip Protocol Volume Policy Idle-Time Local-Reqs Remote-Reqs -------------- -------- --------- -------- ------------ ---------- ---------- Trunking ------- client_ip nfs4.2 volume_name default 0s 777466141 0 false

root@server-name1:~:> tcpdump -i interface_name -ne host management_lif_ip

tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

listening on br-mgmt, link-type EN10MB (Ethernet), capture size 262144 bytes

没有使用 LIF management_lif_ip 的挂载点

root@server-name1:~:> mount | grep nfs

没有带有 management_lif_ip 的挂载点
