Shuhei Matsumoto 44ab133f70 example/nvmf: Fix the case when thread is terminated by communicating with other threads As we have done for SPDK reactor, SPDK thread termination needs communication among SPDK threads. So At application shutdown, create the while loop until all threads are destroyed and in the loop, check each thread is exited, and destroy the thread if exited or mark it as exiting and retry checking after traversing other threads.

NVMe-oF target without SPDK event framework

Overview

This example is used to show how to use the nvmf lib. In this example we want to encourage user to use RPC cmd so we would only support RPC style.

Usage

This example's usage is very similar with nvmf_tgt, difference is that you must use the RPC cmd to setup the nvmf target.

First, start this example app. You can use the -m to specify how many cores you want to use. The other parameters you can use -h to show. ./nvmf -m 0xf -r /var/tmp/spdk.sock

Then, you need to use the RPC cmd to config the nvmf target. You can use the -h to get how many RPC cmd you can use. As this example is about nvmf so I think you can focus on the nvmf cmds and the bdev cmds. ./scripts/rpc.py -h

Next, You should use the RPC cmd to setup nvmf target. ./scripts/rpc.py nvmf_create_transport -t RDMA -g nvmf_example ./scripts/rpc.py nvmf_create_subsystem -t nvmf_example -s SPDK00000000000001 -a -m 32 nqn.2016-06.io.spdk:cnode1 ./scripts/rpc.py bdev_malloc_create -b Malloc1 128 512 ./scripts/rpc.py nvmf_subsystem_add_ns -t nvmf_example nqn.2016-06.io.spdk:cnode1 Malloc1 ./scripts/rpc.py nvmf_subsystem_add_listener -t rdma -f Ipv4 -a 192.168.0.10 -s 4420 -p nvmf_example nqn.2016-06.io.spdk:cnode1

Last, start the initiator to connect the nvmf example target and test the IOs $ROOT_SPDK/example/nvme/perf/perf -q 64 -o 4095 -w randrw -M 30 -l -t 60
-r "trtype:RDMA adrfam:IPv4 traddr:192.168.0.10 trsvcid:4420 subnqn:nqn.2016-06.io.spdk:cnode1"
