From 7cd7e91ab3de5aa75dc963cb08b0618c1885cf0d Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Wed, 5 Dec 2018 16:35:00 +1100 Subject: [RHEL7.7 PATCH 05/21] 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.
