I need to disable transparent_hugepage at boot time (before some big services start up). This is on centos7 machines using SystemD.
There are many ways to do this. It isn't clear which is the best/easiest way to do it via puppet. (Here is a list of ways to do it manually http://answers.splunk.com/answers/188875/how-do-i-disable-transparent-huge-pages-thp-and-co.html and here is one more http://docs.mongodb.org/manual/tutorial/transparent-huge-pages/) The most straightforward way seems to be to edit /etc/default/grub: Change this line in /etc/default/grub and add transparent_hugepage=never to the GRUB_CMDLINE_LINUX. i.e. Change this line: GRUB_CMDLINE_LINUX="rd.lvm.lv=centos_ks-7/root rd.lvm.lv=centos_ks-7/swap crashkernel=auto vconsole.font=latarcyrheb-sun16 vconsole.keymap=us intel_pstate=disable rhgb quiet transparent_hugepage=never" to GRUB_CMDLINE_LINUX="rd.lvm.lv=centos_ks-7/root rd.lvm.lv=centos_ks-7/swap crashkernel=auto vconsole.font=latarcyrheb-sun16 vconsole.keymap=us intel_pstate=disable rhgb quiet transparent_hugepage=never" However doing that in puppet (even with Augeas) seems non-trivial. Any suggestions? Tom P.S. I'm also considering making a systemd "unit" that just sets the parameter and is scheduled to run before any of the major services on the machine. However that seems like a long way to do a short thing. -- Email: t...@whatexit.org Work: tlimonce...@stackoverflow.com Skype: YesThatTom Blog: http://EverythingSysadmin.com -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
