Issue/Introduction

When we restarted CAPM daemons, we received the Warning message to Run 'systemctl daemon-reload' to reload units. We would like to know is there any impact if we execute this Run command and why we received this message below:

Warning: mysql.service changed on disk. Run 'systemctl daemon-reload' to reload

Redirecting to /bin/systemctl start caperfcenter_sso.service

Warning: caperfcenter_sso.service changed on disk. Run 'systemctl daemon-reload' to reload units

Redirecting to /bin/systemctl start caperfcenter_console.service

Environment

Release : NetOps 20.2

Component : IM Reporting / Admin / Configuration

Cause

 daemon-reload
       Reload systemd manager configuration. This will rerun all generators (see systemd.generator(7)), reload
       all unit files, and recreate the entire dependency tree. While the daemon is being reloaded, all sockets
       systemd listens on behalf of user configuration will stay accessible.

       This command should not be confused with the reload command.

Resolution

Run 'systemctl daemon-reload'
