Thank you for your reply. I fully forgot about the email thread, but I got the fio working
and able to get my project related to developing a tool for IOPS and latency completed.
The problem was device was removed by the administrator and I got it working. My apologies
for not getting back.
I have few questions about how to handle I/O errors in NVMF initiator, am going to start a

This error means your NVMe-oF subsystem does not have any namespaces. That usually means
there is a problem in the configuration file.
NVMF configuration file:
Listen RDMA 172.17.2.175:11345
What version of SPDK are you using? The NVMe directive inside of the [Subsystem] section
was replaced with syntax that looks like this:
Namespace Nvme0n1 1
And Nvme0n1 is defined by the [Nvme] section with syntax like this:
TransportId "trtype:PCIe traddr:0000:00:00.0" Nvme0
See etc/spdk/nvmf.conf.in for a full example. If you upgraded SPDK to a newer version but
didn't update your configuration file, you'll end up with a subsystem with 0
namespaces because it doesn't understand the NVMe directive anymore.
