I hope I have posted the query in the right forum thread. I was trying to setup SPDK on Linux Kernel 5.6.4. While trying to execute t= he NVMe arbitration example, I am facing Starting I/O failed exception. I h= ave added debug prints to get the value of error and it was -22. The attached NVMe SSD has a single namespace of 64MB and 4k sector size for= mat and single controller. Since basic script was giving exception, I tried= reducing the IO count to 1 and io size in bytes to 4096 to keep the IO pro= file simple. But I still faced the same exception. Is there any configuration missing while setting up SPDK? I have tried most of the other examples too, it is observed that NVMe Admin= commands and queue creation is working fine but the example script is unab= le to submit NVM I/O commands to the controller due to the mentioned except= ion. SPDK version Starting SPDK v20.07-pre git sha1 e69375b / DPDK 19.11.0 initialization... Thanks in advance. Regards, Harshit --===============0136338973129867374==--
