Hi Ranjan,
Nice to meet you. I’m adding SPDK mailing list for wider audience (someone may find it helpful someday 😊 ). Maybe it has to do something with additional comments on each line in configuration file – try to remove them. Also in “spdk_rpc_port =4420” you are missing space after “=” – I doubt that this may has something to do with that missing space, but it is always worth trying removing it. Everything else looks good. Let me know if that won’t work – I’ll try to reproduce environment on my side.

Regards,
Maciej

Subject: Fail to start cinder service

Hi Maciej,
I am Ranjan from WDC. Request your  help in understanding as why I am not able to start the cinder service.
I saw some of your patches and looks like you are more into this field. Hence pinging you.

For experiment : devstack as well my client is running in the same server.

My host IP for Horizon (private network) : 192.168.1.14
My target IP where rpc is listening : 192.168.1.111
My target has 2 data ports , one is : 192.168.1.111 and another : 172.168.1.111

Spdk entried in my  Cinder.conf

[spdk]
spdk_rpc_ip = 192.168.1.111 #address to machine with SPDK
spdk_rpc_port =4420 #port to use to send commands to SPDK once running with -r
#spdk_rpc_username = admin#username set in remote_rpc.py
#spdk_rpc_password = admin#password set in remote_rpc.py
target_ip_address = 172.168.1.111 #NVMe-oF interface
target_port = 4420
target_protocol = nvmet_rdma
target_helper = spdk-nvmeof
target_prefix = nqn.1992-05.com.wdc
volume_driver = cinder.volume.drivers.spdk.SPDKDriver
volume_backend_name = SPDK
