Re: [ovirt-users] Error while executing action: Cannot add Host. Host with the same UUID already exists.

18 Jun 2015

      Please compare:

# dmidecode -s system-uuid

At both machines.

If equals then your bios has well known bug, the method to override it is to manually create /etc/vdsm/vdsm.id

Thanks,
i solved it by:
uuidgen > /etc/vdsm/vdsm.id
I was just confused because /etc/vdsm/vdsm.id did not exist at that
point on my new node.
Thanks.

Hi,
I have resolved this in such way.
On the engine host connect to db:
su postgres
psql -s engine
Then delete host from db manualy:
select vds_id from vds_static where host_name = 'HOST_NAME';
delete from vds_statistics where vds_id = 'id';
delete from vds_dynamic where vds_id = 'id';
delete from vds_static where vds_id = 'id';

A log will be nice.
    However, can you please compare /etc/vdsm/vdsm.id <http://vdsm.id>
    in both hosts?
    If not available at new host it might be a bios issue, try to
    uuidgen > /etc/vdsm/vdsm.id <http://vdsm.id> and add host.
