Did you install on client and server Mellanox OFED version 3.3-184.108.40.206?
What is the kernel revision running on client and server?
Could you confirm the FW on the HCA's (both side client & server).
Putting aside NFS, are you able to validate an RDMA connection between client and server?
Hi, Sophie, thank you for reply: noticed that you are referring to MOFED 3.3-220.127.116.11 -- while problem what observed on MOFED-3.3-18.104.22.168 -- upgraded the OFED distro and NFSoRDMA works fine on ConnectX-4 Lx now.
Original problem was observed on CentOS 7.2, 3.10.0-327.el7.x86_64, OFED 3.3-22.214.171.124 & ConnectX-4 LX NICs (server & client identical systems).
Thanks & Regards,
