Weird double server entry and a entry of a deleted machine

[mico]

Hello

I have a weird issue on my second host.
I am not sure what i did exactly (i did change the hostname to all capital)
But now i have the strange thing that there is a double entry of my server in the datacenter view.
The bottom one should not be there.
Also there is a machine with Nr1 100 there that i already deleted.
The second picture is what i get when i click on the 100 entry.
I want to remove the Host02 entry but i don`t know how.
So i need help how to. Does anyone know how to do this?
Thanks

Please check: https://www.thomas-krenn.com/de/wiki/Hostname_ändern_in_einem_produktiven_Proxmox_Ceph_HCI_Cluster its not that easy to change the hostname, you might need to autotranslate it (as its german). But the commands should help you, as there are many locations, where the new names needs to be changed so its works without issues.
