VMFleet Diskspd script shows zeros in output.

Question

Speaking shortly, I decided to stress-test my brand new 4-node S2D cluster.

I started with IOMeter and got the initial results (max IOPS/Throughput on different patterns). Then I thought it would be a good idea to find IOmeter configs that would simulate the real production workload. Sadly, I didn't find anything useful for IOmeter, but discovered the fancy Powershell script called VMFleet that uses MS Diskspd to stress the storage and simulates the "bootstorm".

I followed this blog article during the configuration process to prepare and configure the lab.

set-vmfleet.ps1 script showed me some errors so I replicated all the steps manually.

Next I ran start-vmfleet.ps1 but it seems that output just shows zeros instead of actual results.

For how long should I run the watch-cluster.ps1 to see the results? Have anyone used VMFleet before? This doesn't look like the expected behaviour.

Thanks in advance!

The results should show-up immediately when you run "watch-cluster.ps1".

Did you ran "install-vmfleet.sp1" or just copied everything to the folder manually?

I see what you mean.. I have actually copied everything in the folder. Could it be causing the issue? – B.J.Goodman Jun 15 '17 at 17:09

Yeah, that's exactly the reason. – Strepsils Jun 16 '17 at 12:18
