dax systemd unit files

What is it for?

The goal is to have PMem devices exposed as a system-ram after system reboots, when PMem dimms are ready. In order to achieve that following command

daxctl reconfigure-device --mode=system-ram all

should be executed before kubelet.service starts but not earlier than PMem dimms are available in the OS. This way kubelet and Docker will have visibility on all /sys/fs/cgroup/cpuset/cpuset.mems available on the host node (additional PMem NUMA nodes).

How to use systemd units in this directory?

Run steps below:

  1. Copy dax* files to /etc/systemd/system/:
cp dax* /etc/systemd/system/
  1. Enable necessary unit:
systemctl enable dax-waitdev.path
