Hi Guys,
Im currently cleaning up my kernal setting due my recent upgrades to 302 - and this manual page is useless.
1. if you use the kernal parameter at boot time - this does not remove the defrag warning.
2., if you use the rc.local script this also fails as rc.local runs AFTER the mongo script.
I have found two ways to resolve
eikther add this to /etc/init.d/mongod
echo never >/sys/kernel/mm/transparent_hugepage/enabled
echo never > /sys/kernel/mm/transparent_hugepage/defrag
OR
reorder the scripts numbers in /etc/rc3.d
set S895mongod to S100mongod, so it runs AFTER S99local
