Monitors, managers and MDS duplicates in GUI

PVE 8.1.10

After some updates, rebooting of the nodes, adding new nodes - I ended up with this:



When I try to remove all instances, all disappears, but then when I create new ones, also those dead duplicates create.
How can I clean this?

Hi,

I would first refresh the PVE Web UI by hitting [Ctrl+Shift+R] keys. If that didn't help could you please check the `ceph status` command output?

Refreshing without cache changes nothing, and this is the status from ceph:

I encountered the same problem; it might be due to a duplicate short hostname with fqdn.
The system is started by ceph-mds@sh-xxx-pve-test-151.service via systemd.
I obtained this data from https://10.0.4.151:8006/api2/json/cluster/ceph/metadata

Hi @Chronos.Song I would check the `/etc/hostname` and see if contains only the short node name and that it resolves correctly, then restart or reboot hte affected node.
