To Reproduce Steps to reproduce the behavior: 1.Prepare the spdk configuration file cp /KVSSD/application/kvbench/spdk/spdk/etc/spdk/rocksdb.conf.in /tmp/rocksdb.conf /KVSSD/application/kvbench/spdk/spdk/scripts/gen_nvme.sh >> /tmp/rocksdb.conf

  1. Reserve hugepage cat /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages echo 1024 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages
    1. Setup spdk environment /KVSSD/application/kvbench/spdk/spdk/scripts/setup.sh
    2. Create BlobFS on the device /KVSSD/application/kvbench/spdk/spdk/test/lib/blobfs/mkfs/mkfs e.g. ./test/lib/blobfs/mkfs/mkfs /tmp/rocksdb.conf Nvme0n1

Expected behavior create blobfs correctly.

System environment (please complete the following information) Firmware version : ETA51KCA_20191021_ENC.bin Number of SSDs : 1 OS & Kernel version [e.g., Ubuntu 16.04 Kernel v4.9.5]: Ubuntu 16.04 Kernel v4.13.15 GCC version [e.g., gcc v5.0.0] :5.4.0 User driver version : spdk-18.04 Driver [Kernel or user driver or emulator] : User Driver

Blobfs needs block firmware. Your SSD was downloaded the KV firmware. Please firstly download the block firmware to SSD, then try it again.
