From 7cd7e91ab3de5aa75dc963cb08b0618c1885cf0d Mon Sep 17 00:00:00 2001
From: NeilBrown <neilb@suse.com>
Date: Wed, 5 Dec 2018 16:35:00 +1100
Subject: [PATCH 05/11] Monitor: add system timer to run --oneshot periodically
"mdadm --monitor --oneshot" can be used to get a warning
if there are any degraded arrays. It can be helpful to get
this warning periodically while the condition persists.
This patch add a systemd service and timer which can
be enabled with
systemctl enable mdmonitor-oneshot.service
and will then provide daily warnings.
