Description

ceph-ansible supported os tuning in which a set of options could be specified in your group vars that would be included in a file written to /etc/sysctl.d/ on a given set of hosts. Cephadm should try to include this feature as well.

From ceph-ansible

#  - { name: vm.swappiness, value: 10 }
#  - { name: vm.min_free_kbytes, value: "{{ vm_min_free_kbytes }}" }
