Taget detection NVME-oF using StarWind Initiator not working :(

TrueNAS General

I try to use NVME-Of as alternative for iSCSI.

So:

  • I defined a NVME-oF share on my TrueNas system (25.10.1)
  • Added related rules on my firewall
  • Downloaded and installed the ‘StarWind NVME-oF Intitiator’
  • Installed it on my WIndows11 Pro PC
  • Defined a portal under Discovery
  • And watched for the Target to appear …….

And that did not happen …..

  • I disabled the firewall …. did hot help
  • Looked in the log (C:\ProgramData\StarWind\NVMeoF-GUI\Logs\NVMeoF-GUI.log)
    (so connection to portal fails)
  • Started Wireshark looking for a cause

And where the StarWind log tells me that it tried to reach the portal ip …. my Wireshark log tells me that there are no packages from my pc in the direction of the portal (my TrueNas system).

Which definitively explains why it can not find the target …..

Does someone understands the problem / know how to solve this !?

Has any one a working NVME-oF setup between TrueNas and a Windows PC !? If so how did you manage that?

I tried further and for some reason the windows client does try to reach my TrueNas system now. However it still does not work.

There is minimal communication to setup a connection I assume, but it fails

No idea why.

Hello,

Also for me doesn’t work.

The only way that I find to connect to NVME-Of Target is to use Chelsio tool (I have direct connection form Win11 Pro to TrueNAS using two T62100-CR).

Best Regards,

Antonio

I discussed this with StarWind. Together with a StarWind support engineer we did investigate the problem using my network / setup using the actual StarWind 2.0 initiator.

Since I am using the TrueNas community edition, which only support NVME-oF via TCP, we did tests via TCP only.

We did a couple of tests looked at the initiator behavoir and made (wireshark) traces. As a result he StarWind engineer agreed that there is a problem. StarWind will further analyze it.

I am on the list of persons to be informed about about solutions / progress. I will post an update here if there is a solution.

There are people using the driver, so probably the issue is not effecting every one (especially not if they using RDMA)

Any update on this? I was just trying the same thing and am having the exact same result.

Just tried connecting to a fresh install of Truenas 25.10 from 2 different Windows server 2025 hosts and failed with the same issue.

IS anyone able to connect via Nvme-OF/TCP ?
