changing swappiness - permission denied

Question

I use "echo 0 > /proc/sys/vm/swappiness" to set swappiness but even if I'm root i've got access denied. Do you know what should I do to unlock it ?

I suspect SELinux. Try getenforce and if it returns enforcing, you can temporarily disable SELinux with setenforce 0. For permanent disablement see /etc/selinux/config.

Before disabling SELinux you may try sysctl -w vm.swappiness=0.

You might want to check if SELinux is active. It imposes restrictions even on root.

The commmand sestatus will tell you if SELinux is active.
