Hi,

I understand that you are running a support distribution Redhat 7.6 ? right ?

If it is the case, and you want to investigate your current problem, I suggest you to open a case at support@mellanox.com

You can also look at the Redhat doucmentation regarding nfs server configuration and espcially nfs over rdma paragraph.

Thanks

Marc
