What happens when Headroom Management goes wrong:

Q. Why were players unable to access Yahoo! Fantasy sports on November 11th?
A. We have giant machines called “filers” that store all of the data about your teams and leagues. These filers serve millions of files every hour for our games, and normally our machines can handle this with no problem. Recently, we discovered a hardware issue in one of the filers that caused the other one to overload. We replaced some hardware, re-configured the setup, and did some testing. However this Sunday – at approximately 12:15 pm ET – the new configuration failed. This created an overload on storage capacity and took the Fantasy part of our site down.

Comment on 7-Mode to Clustered ONTAP Transition by Jonathan Perel http://recoverymonkey.org/2016/02/05/7-mode-to-clustered-ontap-transition/#comment-18096 Fri, 12 Aug 2016 20:51:09 +0000 http://recoverymonkey.org/?p=775#comment-18096 Is there a reason why the copy-free 7-Mode to Cluster mode migration requires a purchasing a new controller? Wouldn’t it be possible to purchase a new disk shelf, export the Mode-7 settings, disconnect the controller from the existing 7-mode shelves, connect the existing controller to the new shelf, set up the controller as a new Cluster on the new shelf, connect the 7-mode shelves to the controller, and import the 7-mode settings. Is there a reason why this would not be possible? If so, there still be a way to roll back?

I suspect their is an IO performance issue caused by very intermittent latency problems.

The subsystem vendor shows figues which demonstrate that the average IOPS is very good.

What standard Unix tools can be used to determine the real latency on an IO subsystem.
