Avnet SmartEdge IoT Gateway - cgroup memory

stopje over 5 years ago

Hi,

On avnet Raspbian system (as delivered with IoT gateway) I have hard time to enable cgroup memory.

I added to cgroup_enable=memory cgroup_memory=1 /boot/cmdline.txt with no effect.

Is there any special trick needed?

It depends on what release you have stopje . https://github.com/raspberrypi/linux/commit/ba742b52e5099b3ed964e78f227dc96460b5cdc0 explains the confusion. Please post the release from:
uname -a

uname -a gives:
Linux raspberrypi 4.14.79-v7+ #91 SMP Tue Jul 16 05:42:32 PDT 2019 armv7l GNU/Linux
I used both cgroup_enable=memory and cgroup_memory=1 but unfortunatelly it still didn't work. Might it be related to some avnet modifications?

Here is all the details cgroups(7) - Linux manual page .
the availability of the cgroups feature is governed by the CONFIG_CGROUPS kernel con‐
figuration option. So maybe it was not built with this!
Linux cgroup started version 2 in Linux 4.5. Since you are not there yet, an upgrade or newer version may help.
Check docker for which you need. Version 1 may be OK! Or not.
Can you use standard Rasbian?
