Hi,
it's getting a little too long, so please forgive the top post. The
engine emits the message "Host with the same address already exists."
only if you trying to add host with the same hostname it doesn't have
any connection to it's ID, so please check if your hosts have unique
hostnames (e.g. I ran into this when I didn't get hostname from dhcp and
both of my hosts were localhost.localdomain).
Regards,
Jirka

Hi there.
I'm trying to install a hosted-engine on our second node (fist
engine
runs on node1).
But I always get the message:
[ ERROR ] Cannot automatically add the host to the Default cluster:
Cannot add Host. Host with the same address already exists.
I'm not entirely sure what I have to do when this message comes, so
I
just press ENTER:

To continue make a selection from the options below:
(1) Continue setup - engine installation is complete

Is there any other interaction required prior to selecting "1"?
In the Web Gui I get the following message:

I admit I never tried that. Not sure how exactly it's supposed to work.
A bit more details:
Normally, a host is registered only in the engine's database. A hosted
engine is additionally registered in a special hosted-engine metadata
file managed by the ha daemon [1]. The question above appears if the host id
is found in this metadata file. It seems we never check if it's already
in the engine database - the assumption is that if an existing host is
re-purposed as a hosted-engine, it should first be "uninstalled" - at least
not be in use (no VMs) and removed from its cluster/dc/the engine.

what type of hardware is this? check the host uuid is not the same
on
both please.
http://lists.ovirt.org/pipermail/users/2014-September/027278.html
Hi,
this is Supermicro Hardware. But the uuids differ. Anyway, I
regenerated
the uuid on node2. But I first have to fix another problem. After a
reboot the first engine on node1 doesn't start because it says the
storage path cannot be found. arrgh
I will investigate this and report my findings.
Cheers,
Stefan

Well everything is up and running again but I still have the same
problem. I did a uuidgen > /etc/vdsm/vdsm.id on ovirt node 2 and 3
even
though the uuids were different already.
What does ovirt mean by "Host with the same address already exists"?
What HOST is it referring to?
Greetings,
Stefan
oh, not same uuid, rather same host name (like ip address or dns name
used to access it)
it - is the engine or the ovirt-node? The nodes have definitely
different ip addresses and dns entries. This is verified.
If it is the engine then I might have a problem understanding some
things I Basically want one engine that runs on each node, if needed.
Cheers
The hosts.
Didi/Sandro?
It will probably be simplest to remove the second (and third?) host
from then engine, then try again.
