Subject: Setting huge_pages=off when HugePages are allocated in Linux?
Date: Wed, 28 Jan 2026 10:31:36 -0500
Message-ID: <CANzqJaD0Nj2SvXrGCM-p_TUaeN84TzRteo7jxqSdARaZDiXABA@mail.gmail.com> (raw)
In the example in this (quite helpful) Cybertec post, 10475 HugePages are
allocated.
https://www.cybertec-postgresql.com/en/huge-pages-postgresql/
If we set "huge_pages = off" within PG and then restart PG, will Linux see
those 10475 HugePages as off-limits to normal 4KiB allocations?
