Re: [ovirt-users] Change ip host

[Marcin Michta]

  
  
So, you can do it without remove node from engine, but when you use
FQDN in engine.
Put the host in maintenance mode. Make sure that inside /etc/hosts
of the engine you have entered new address.
Next, edit

/var/lib/vdsm/persistence/netconf/nets/ovirtmgmt on the node where
is configured IP address and run

vdsm-tool restore-nets. Than restart your node. Inside engine should
be able to put out of maintenance mode this host. 
That was tested by my.

Regards.

  Hi,
I have installed ovirt 3.6 with 1 manager and 1 host
I need to change the ip, I decided to do the following:

4. reinstall the host with the correct ip
5. add the host to the ovirt infrastructure

questions:

1. is there the possibility of losing vm during this
operation?
2. is it necessary remove the host for the re-installation?
3. is it necessary put the host in maintenance mode to
remove it from ovirt infrastructure?

thanks a lot

Re: [ovirt-users] Change ip host

[Fernando Fuentes]

Nicola,

I guess this all boils down on the type of storage domain you have
setup... If its shared than your vms will be ok. If its Local than if
something goes wrong with the hosts than you could be in lots of
trouble.

I went through something similar... I had to move DC (one host on the
main DC) the hosts took a crap... I thought I lost everything but to my
understanding the VM's are in my storage domain (iSCSI) as soon as I
brought a new host online (same hostname) it all worked just fine.

My procedure was as follow:

Remove broken host from ovirt.
Re-install host
re add host to ovirt

Things came back online on its own... WIN :)
