    Description

      The obdechosurvey test 3 on the Master has following error:

      tgt_request_handle()) @@@ echo_srv: No target for connected export
      

      According to client's log, commands for odbecho were send and received by server successfully. After receiving the server has been provided attach and setup of the obdecho without errors.
      During setup the obdecho was not configured into obd_device and doesn't represented in lu device but use legacy obd device stack. In that case it lack an ability to execute an any network requests so have a root cause of test failing.
      Obdecho survey test 3 uses a special obd srv target to simulate fast disk storage. Previously it replaced an obdfilter module in lustre stack and provides a operations over fake device. Then obdfilter replaced with OFD and unified target project landed but not obd echo srv. Now, the obd echo srv has to be also rewrited to use an lu device stack with target support.

            spitzcor the Fix Version is not an indicator of the progress it is a marker of the importance relating to the release. Let's discuss in more detail in the upcoming LWG call.

            Considering the progress here, can we set the Fix Version to 2.11.0?

            I've made quick review of the code to update, that shouldn't be difficult, most of code can be copied from OFD and adapted for Echo Server.

            Yes, I agree that current echo server target is not functional and should be updated. At the same time that looks wrong this test passes at Maloo, seems it does just nothing.
