Environment

RAID Model: All
Host Hardware: All
Operating System: Linux

Issue

Running performance tests can take a long time if done manually. This scripts automates this process.

Resolution

Download link 

1. Download the file and save it as graid-bench-script.zip in the current directory
2. Create the "graid-bench" folder 

  mkdir -p ./graid-bench

3. Extract the contents of the downloaded file to the folder

  unzip -q graid-bench-script-0.1.4f.zip -d ./graid-bench -x __*

4. cd to "./graid-bench" folder, and edit the "graid.conf" file as you want.

cd graid-bench
vi graid-bench.conf

# List all the NVMe devices
# must match NVME_COUNT
NVME_LIST=("nvme8n1" "nvme9n1" "nvme10n1" "nvme11n1" "nvme12n1" "nvme13n1" "nvme14n1" "nvme15n1")

# Set the RAID controller model
RAID_CTRLR=SR1010

# Set the filesystem to use

# Set the list of thread counts to use
# aleast keep the "afterdiscard"
TS_LS=("afterdiscard" "afterprecondition" "aftersustain")

# Enable or disable quick tests
QUICK_TEST=true

# Enable or disable full sequence testing(total/4)
SCAN=false

# Enable or disable testing with job-depth statistics
LS_JB=false

# Set the list of job-depth statistics to use
JOB_LS=(1 4 8 16 64)

# Set the list of queue depths to use
QD_LS=(1 4 8 16 64)

# Enable or disable testing of physical drives
RUN_PD=true

# Enable or disable testing of virtual drives
RUN_VD=true

# Enable or disable testing of all physical drives
RUN_PD_ALL=true

# Set the runtime for testing physical drives
PD_RUNTIME=180 # 3 minutes

# Set the runtime for testing virtual drives
VD_RUNTIME=180 # 3 minutes

# Enable or disable testing of software RAID
RUN_MD=false

# Set the name of the software RAID device to test
MD_NAME="md0"

# Set the block size for software RAID tests
MD_BS=128

# Enable or disable dummy tests
DUMMY=false
   3. execute the graid-bench.sh 
      ```sh
       $ bash graid-bench.sh
      ```
   4. after it finishes, it will generate a tar file call"graid_bench_result_[yourhostname]-[timestamp].tar", please  send back to graid
