Hi Jonathan,

Thanks for the detailed report.  Would you mind filing a GitHub issue?  We'll have a bug scrub tomorrow morning and a GitHub issue will make sure it gets looked at.

Regards,

-Jim

    Hi,

    I converted my old conf file using config_converter.py but there is no
    Nvme section in the json file output. When I run nvmf_tgt I get these
    errors.

    Not sure why there is an iscsi_set_options method in my json.  This is
    the nvme section in the conf file:

    [Nvme]
      TransportId "trtype:PCIe traddr:0007:01:00.0" Nvme0
      HotplugEnable Yes
      HotplugPollRate 1000000

    And my json is below. Is there something missing in it?
