如何将数据填充到多个磁盘中的大小？

Question

我在Windows操作系统中创建了4个挂载点磁盘。我需要将文件复制到阈值（例如50 GB）。

我试过vdbench。它工作正常，但它最后抛出异常。

compratio=4
dedupratio=1
dedupunit=256k

* Host Definition section

hd=default,user=Administator,shell=vdbench,jvms=1
hd=localhost,system=localhost

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

以下是vdbench的例外情况。由于这个原因，我的调用脚本会失败。

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?

我在Windows机器上使用PowerShell。即使像Diskspd这样的其他工具有办法将数据填充到某个阈值，请提供给我。

Answer 1

我自己找到了答案。

我使用Diskspd.exe完成了这个操作，如下所示

以下命令在上述磁盘文件夹中填充50 GB数据

.\diskspd.exe -c50G -b4K -t2 C:\UnMapTest-Volume1\disk1\testfile1.dat 

根据我的要求，它比Vdbench简单。

注意：但它没有真正的数据，所以阵列侧磁盘大小没有显示大小
