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 :) Regards, -- Fernando Fuentes ffuen...@txweather.org http://www.txweather.org On Wed, Jun 29, 2016, at 09:24 AM, nicola.gentile.to wrote: > 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: > > 1. put the host in maintenance mode > 2. remove the host > 3. update the information on the dns server with new ip > 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 > > Nicola > _______________________________________________ > Users mailing list > Users@ovirt.org > http://lists.ovirt.org/mailman/listinfo/users _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
