Hi guys, what's the right way to change IP ( or FQDN ) on the host in replica 1 and 3 configuration? Thanks in advance. Best regards.
I think the best is:Remove the host from oVirt, remove-brick the brick on the host, peet detatch, reinstall, add-brick in gluster, add in ovirt Best Regards,Strahil Nikolov On Wed, Jul 7, 2021 at 17:20, radchenko.anatoliy@gmail.com<radchenko.anatoliy@gmail.com> wrote: Hi guys, what's the right way to change IP ( or FQDN ) on the host in replica 1 and 3 configuration?

Hi Strahil, thanks for your response. i understand. But yesterday happened this on one of cluster that was off for a long time: router could not assign same ip and assigned another IP and all went well - cluster is up, gluster with briks is ok (gluster is configured with another internal network). Which mechanism made ip of ovirtmgmt change in this case? Is it possible simply change dhcp parameters on router and assign by MAC new ip?

Usually when the IP is taken by a different interface, the server does not have much of a choice and assigns a different one. This is a good thing because after reboot etc. you won't end up with different IP on the same interface.
Is it possible simply change dhcp parameters on router and assign by MAC new ip?
Usually DHCP server support so called "static lease", you basically tell the server that this particular MAC will always receive IP a.b.c.d. The server is then aware of it and does not serve this IP to anything else, if you need to change the IP just change the static lease record for the MAC address. Just be aware that the lease has some expiration time and won't be renewed until it expires or something else happens that would force the interface to ask the DHCP server again. Thanks again

Interfaces on oVirt hosts act just like regular DHCP client so there is not much from oVirt point of view that can be done.

I agree, you either use static IPs outisde the dhcp range, or you provide static dhcp leases (mac to ip binding). In worst case scenario, changing the dns A/AAAA & PTR records to the new IP should bring you to a working state. As it was mentioned, it's pure DHCP Server-Client relationship and nothing specific to oVirt.
