<div dir="ltr"><pre style="white-space:pre-wrap;color:rgb(0,0,0)">hi, I'm sorry to ask for help if it is a common question. I noticed that in glusterfs NLMv4 is only available over TCP,but not available over UDP as the show of "rpcinfo -p" when using glusterfs to export volumes through NFS protocol. The result is as follow:</pre><pre style="white-space:pre-wrap;color:rgb(0,0,0)"><pre style="word-wrap:break-word;white-space:pre-wrap"> program vers proto port service
