How to fill data upto a size in multiple disk? - powershell

Question

I am creating 4 mountpoint disk in Windows OS. I need to copy files up to a threshold value (say 50 GB).
I tried with vdbench. It works fine, but it throws an exception at last.
compratio=4
dedupratio=1
dedupunit=256k
* Host Definition section
hd=default,user=Administator,shell=vdbench,jvms=1
hd=localhost,system=localhost
********************************************************************************
* Storage Definition section
fsd=fsd1,anchor=C:\UnMapTest-Volume1\disk1\,depth=1,width=1,files=1,size=5g
fsd=fsd2,anchor=C:\UnMapTest-Volume2\disk2\,depth=1,width=1,files=1,size=5g
fwd=fwd1,fsd=fsd*,operation=write,xfersize=1m,fileio=sequential,fileselect=random,threads=10
rd=rd1,fwd=fwd1,fwdrate=max,format=yes,elapsed=1h,interval=1
Below is the exception from vdbench. Due to this my calling script would fail.

05:29:14.296 Do you maybe have more threads running than that you have
05:29:14.296 files and therefore some threads ultimately give up after 10000 tries?

I am using PowerShell in a Windows machine. Even if some other tools like Diskspd is having way to fill data up to some threshold then please provide me.

Answer 1

I found the answer by myself.
I have done this using Diskspd.exe as below
The following command fill 50 GB data in the mentioned disk folder
.\diskspd.exe -c50G -b4K -t2 C:\UnMapTest-Volume1\disk1\testfile1.dat
It is very simple than Vdbench for my requirement.
Caution : But it is not having real data so array side disk size is
not shown up with the size
