Vdbench multi-node test file system read and write

Procedure:

1. First install java (including master control node) on each node that needs to be tested

two。 Then make sure that the hostname of each node is different, and it is best to turn off each firewall

3. Mount the network storage to be tested on each node

4. Then operate each node in turn, enter the vdbench directory with cmd, and run "vdbenchrsh" (enter listening mode)

5. Open the host file on the master control and write down the ip and hostname of each node.

6. To the master control node, use cmd to enter the vdbench directory and run "vdbench-f parmfile" (parmfile is a pre-configured configuration file)

Write operation profile:

Hd=default,shell=vdbench

Hd=hd1,system=10.20.16.96

Hd=hd2,system=10.20.16.98

Hd=hd3,system=10.20.16.99

Fsd=default,depth=1,width=1,files=3,size=5g

Fsd=fsd1,anchor=Z:\\ 1

Fsd=fsd2,anchor=Z:\\ 2

Fsd=fsd3,anchor=Z:\\ 3

Fwd=default,operation=write,xfersize=1M,threads=2,fileio=random,fileselect=random,openflags=directio

Fwd=fwd1,fsd=fsd1,host=hd1

Fwd=fwd2,fsd=fsd2,host=hd2

Fwd=fwd3,fsd=fsd3,host=hd3

Rd=rd1,fwd= (fwd1-fwd3), fwdrate=max,format=yes

Read the operation profile:

Hd=default,shell=vdbench

Hd=hd1,system=10.20.16.96

Hd=hd2,system=10.20.16.98

Hd=hd3,system=10.20.16.99

Fsd=default,depth=1,width=1,files=3,size=5g

Fsd=fsd1,anchor=Z:\\ 1

Fsd=fsd2,anchor=Z:\\ 2

Fsd=fsd3,anchor=Z:\\ 3

Fwd=default,operation=read,xfersize=1M,threads=2,fileio=random,fileselect=random,openflags=directio

Fwd=fwd1,fsd=fsd1,host=hd1

Fwd=fwd2,fsd=fsd2,host=hd2

Fwd=fwd3,fsd=fsd3,host=hd3

Rd=rd1,fwd= (fwd1-fwd3), fwdrate=max,format=no

Interpretation of profile parameters:

Hd

Host definition (hd=default is the default configuration and will be applied to every hd you define)

System

IP address or network name

Fsd

Name of the file system definition

Depth

The number of levels to create under the locator

Width

The number of directories to be created under the locator

Files

Number of files to create at the lowest level

Sizes

File size to be created

Anchor

The directory in which the directory structure will be created (the mounted test directory)

Fwd

Name of the file system workload definition

Operation

Mkdir, rmdir, create, delete, open, close, read, write, getattr and setattr. Select a single file operation to perform.

Xfersizes

Block size processed by data transfer (read and write operations)

Threads

The number of concurrent threads for this workload. Each thread needs at least 1 file (the number of threads cannot be greater than the number of files)

Fileio

Random or sequential, indicating how the file Iramp O will be executed

Fileselect

Random or sequential, identifying how to select a file or directory

Rd

Run definition

Fwdrate

Number of file system operations performed per second

Format

Yes / no / only / restart / clean / directories

Actions to be performed before starting to run

Yes: delete the previous file structure and recreate directories and files according to the configuration file

No: the original file directory structure is used by default, and no files are created.

Elapsed

The running duration in seconds. Default is 30s.

Interval

Report interval sequence number, default 1s

Openflags

Use the "directio" value in Windows to eliminate caching

Statement interpretation:

The report output by default is in the output folder under the program directory

(you can also specify the report location "vdbench-f parmfile-o C:\ test\" when running the program.)

In the default report folder, mainly look at summary.html and totals.html

The entry data of "starting RD=format_for_rd1" in the report is to initialize the test environment (create folders, empty files, etc.), mainly looking at the next entry (self-defined)

Summary.html: record all the data information

Totals.html: record the average data after all data calculations

Note:

1. Test environment: multi-node, windows, file system, for testing linux/ block devices, please see the manual.

two。 The name of the configuration file is customized. for more parameters of the configuration file, please see the manual.

Appendix: (sample configuration file for single node is as follows)

Fsd=fsd1,anchor=C:\\ test,depth=1,width=1,files=2,size=5g

Fwd=fwd1,fsd=fsd1,operation=read,xfersize=1M,threads=1,fileio=random,fileselect=random,openflags=directio

Rd=rd1,fwd=fwd1,fwdrate=max,format=no,elapsed=30
