  1. make sure IP and RDMA network is OK. but does not setup nvme target. 2, run benchmark with below steps

then the application will hang at below code: at the endpoint.connect part. it will hang, never return.

FabricsConnectResponseCqe connect(long timeout, TimeUnit timeoutUnit) throws IOException { NativeBuffer buffer = new NativeByteBuffer( ByteBuffer.allocateDirect(RdmaCmRequestPrivateData.SIZE)); RdmaCmRequestPrivateData privateData = new RdmaCmRequestPrivateData(buffer); privateData.setQueueId(queueId); privateData.setRdmaQpReceiveQueueSize(submissionQueueSize); privateData.setRdmaQpSendQueueSize((short) (submissionQueueSize - 1)); this.endpoint.getConnParam().setPrivate_data(buffer.getAddress()); this.endpoint.getConnParam().setPrivate_data_len((byte) RdmaCmRequestPrivateData.SIZE); InetSocketAddress socketAddress = controller.getTransportId().getAddress(); try { //FIXME: rejected requests are not handled by DiSNI //FIXME: check for overflow endpoint.connect(socketAddress, (int)TimeUnit.MILLISECONDS.convert(timeout, timeoutUnit)); } catch (Exception exception) { throw new IOException(exception); }

It will after the timeout. Reduce the timeout if you want it to happen earlier. Otherwise if that does not work open a ticket in the Disni repository.

BTW you can set the timeout with Controller.connect there is an overload which allows you to set it: https://github.com/zrlio/jNVMf/blob/master/src/main/java/com/ibm/jnvmf/Nvme.java

got it. thank you so much!~, timeout is Ok so far. I will see if we need fail immediately later. can you help raise ticket on libdisni?
