Data Protection: In progress

Let’s see – 75 hours to rebalance after replacing one drive and I have three more drives to do. That’s 12.5 days of waiting for the automation to do its thing.

It would take maybe 36 hours to rsync all of my Drobo’s content over to a few external USB drives then I can just swap all the drives in one shot, do a low-level rebuild, then rsync the content back over.

Heisenberg Monitoring Uncertainty Principle

In certain implementations of software monitoring solutions, the type, quantity, and frequency of monitoring – the system or service checks – can result in an increase in load on the systems being tested. This increased load can lead to the flawed interpretation that additional monitoring tools are necessary to identify the load factors, resulting in further-increased load.

Or, to summarize: throw so much monitoring at a platform that it unexpectedly increases load, which prompts additional monitoring. Repeat.

Or, to summarize the summary: You cannot observe any system without impacting it.
