It seems like someone thinks that linux servers should never use any swap. This swapped_warn triggers if you've used more than 50 MB of swap space. I find this silly..
You can tune it using something like "mmchconfig mmhealth-gpfs-swap_alert_threshold_kb=2000000 --force", but I wouldn't want to pollute my config with such settings.. Maybe just disable it using "mmhealth event hide swapped_warn". -jf On Sun, Feb 15, 2026 at 11:33 PM Jonathan Buzzard <[email protected]> wrote: > > > I have a question about the swapped_warn event.
