Disable Software RAID Monitor (mdmonitor) The 'mdmonitor' service is used for monitoring a software RAID array; hardware RAID setups do not use this service. The 'mdmonitor' service can be disabled with the following command: '$ sudo systemctl disable mdmonitor' If software RAID monitoring is not required, there is no need to run this service. Fix: # # Disable mdmonitor.service for all systemd targets # systemctl disable mdmonitor.service # # Stop mdmonitor.service if currently running # systemctl stop mdmonitor.service oval:org.secpod.oval:def:48317 oval:org.secpod.oval:def:48317 oval:org.secpod.oval:def:48782 SCAP Repo OVAL Definition 2018-11-08
