Splunk warning [ ref:_00D409oyL._5003317y65P:ref ]
Hello Garrett -
Thank you for contacting Splunk Technical Support. The second post-er is correct; it doesn't matter if defrag is set to never - if you're OK with seeing WARN'ings in the log.
We advise to turn off both. Our documentation points to an Answers page that has been verified by Splunk as correct, and it specifically describes turning off both.

https://answers.splunk.com/answers/188875/how-do-i-disable-transparent-huge-pages-thp-and-co.html
So, run with that and you'll be good to go!

p.s. To clarify my last email: Leaving defrag at "always" does not have a performance impact, but you will see the warning in the log. We don't consider this a bug, because we ask that it also be turned off, per the verified Answers post with instructions.
I hope that's more clear.
Cheers,
Eric Ryder
