Re: [EXTERNAL EMAIL] Re: [uyuni-users] RE: Uyuni System ID: not incrementing since upgrade.

Hi Simon, I am not sure if it can help but i have fixed duplicate ID issues in the past following this giude. https://www.uyuni-project.org/uyuni-docs/uyuni/administration/tshoot-registe... Regards On 28/09/2020 09:09, Simon Avery wrote:

Hi Silvio

Thanks for this - this does indeed look to be the core of the issue;

machine1# cat /etc/machine-id 57dcc3a1bbed44f6a97dc4c8058eb4d3

machine2# cat /etc/machine-id 57dcc3a1bbed44f6a97dc4c8058eb4d3

I don't know the history of these machines, but cloning does seem possible. Both machine co-existed on Spacewalk okay, but of course they used osad and rhnsd which presumably don't care about this value.

Thanks to you and Robert for your help - I think I'm good to take it on from here.

Regards

S

I'm puzzled - how could both machines get the same ID? Surely Uyuni issues it to the client during the bootstrap process? The machine-id is a unique identifier that comes either from hardware, or from your virtualization software, or in worst case randomly generated - but it should really be unique.

Uyuni does _not_ set it, rather it uses it to determine if a client is the same of another that's already registered or not (despite possible changes in hostname, IP addresses and so on).

Note that the machine-id is very different from the minion key, or the name that you see in the Uyuni Web UI!

You can learn more about machine-id here:

https://www.man7.org/linux/man-pages/man5/machine-id.5.html

It is a requirement that any Uyuni client has a unique and fixed machine-id. Note that if you clone VMs the machine-id might be cloned as well, so you need to change it.
