Proxmox fresh install on debian: cluster already exist

[emmanuelvargas]

Hello all,
I have a very strange issue on a new proxmox 8.2.4 install on a deb12 :
I followed the instruction (i reinstall several time to ne sure and still the same)

Once the install is done i connect to the gui to join another proxmox fresh install and surprise it s look like by default there is already a cluster existing (named "debian").

Did i missed something?
Thanks

Still not found any clue on it and cannot find any other thread with this issue :/

Since you're saying installation on top of debian:
Is there a reason to not use the default proxmox installer?
Which instructions did you follow to do the installation on top of debian, the one on the wikie [1] or something else?
Have you already tried following the "seperate node" instructions, including the part to prepare the host for being in a new cluster?

Yes there is a reason : we generate a specific iso with provisioning information and some internal tools for monitoring and pre-setup the servers on for a lot of different reason so i cannot install an iso for prod (I could do it for my test but would like to in the same env that for prod)

Tried with [1],
tried also with an ansible job that only applying the steps in the wiki
tried also with this ansible job : https://github.com/lae/ansible-role-proxmox (same result)

once the installation is done I follow the 'separate" instructions you mentioned and this is working : after that i can join the cluster but in my point of view this is not clean and sometime i had to fight to having this separate working (sometime work on first try and sometime need to reinstall to have the seperate working ...)

So I would like to avoid separate the host to re-join another cluster.

is there any log somewhere to try to find which step is creating the cluster during the installation?

Many thanks

The only logs I know about creating/joining a cluster are (from within the GUI) found under <node> -> Task History -> Filter -> Task Type: "clustercreate" and/or "clusterjoin"

Also, have you already tried using a "clean" debian iso and installing on top of that (to see if maybe one of your custom additions is to 'blame' for the cluster-creation.)
