No, not visible in the DB. Just see in GUI...

Once the service isn't visible anymore (eg. reboot), it will disappear from the GUI.

I've rebooted several times and the ghost monitor stays in the GUI...

I've rebooted several times and the ghost monitor stays in the GUI...

Before or after you disabled the service?

Before or after you disabled the service?

Alwin, I figured out how to get rid of the ghost monitor today...
Go to Shell on node with ghost monitor
ls /var/lib/ceph/mon #should see name of monitor
rm -rf /var/lib/ceph/mon/<name of monitor>

I then navigated to Ceph page in GUI and the ghost monitor was gone...

systemctl disable ceph-mon@<node-name>.service, replace the node name with the one you want to disable.

Not working.
