I think it could be a combination of both the vSAN node failure and the Resync throttling.

I believe the vSAN Resync throttling being enabled could also be a cause.

I agree with Stefania, that could definitely cause the issue.

I think the high backend IOPs could be due to a vSAN node failure.

That's a good point, Starr. It's important to consider all possible causes.

Haha, imagine if the correct answers were A and D. The cluster DRS threshold set to Aggressive and the object repair timer value increased? Sounds like a recipe for disaster!

I agree with B and E, but I also think C could be a factor. If vSAN Resync throttling is enabled, it can lead to increased IOPs during the resync process.

I think B and E are the main causes of the high backend IOPs.

I think the correct answers are B and E. A node failure can definitely cause high backend IOPs, and changing the protection level from FTT=0 to FTT=1 would also increase the load on the backend.
