Scenario: Production environment, SharePoint 2016 MinRole Farm, 1 Application with Search Server and 1 Front-End with Distributed Cache. On App server, getting Availability Error

"Available drive space is less than twice the value of physical memory."

I am considering relocating Pagefile.sys to the D drive (80 GB). Researching and found this article: https://blogs.msdn.microsoft.com/chaun/2014/07/09/recommendations-for-page-files-on-sharepoint-servers/

I want to know if someone has tried this approach of relocating pagefile.sys as a way to get free space on the C drive (80 GB size) on SharePoint 2016 and get rid of this Availability error in Central Admin.

Just disable the health analyzer rule. Monitor your disk free space via other means. The rule is nonsensical given it needs 5*RAM for free disk space, which doesn't make sense except for a full dump with a BSOD. This isn't the default for Windows (it takes a mini dump instead).

  • Thank you @Trevor Seward for answering, but this is not the 5*RAM rule, this is the other one that is looking for 2*RAM. Do you recommend disabling as well as for the 5*RAM?
