Drop_Cache in LXC container

[yena]

Is it possible to exec this command inside a LXC container ?

echo 3 > /proc/sys/vm/drop_caches
bash: /proc/sys/vm/drop_caches: Read-only file system

If not, can i exec a command on the Container but running this on the Host with
echo 3 > /proc/sys/vm/drop_caches ?

Thanks!
