Thanks for the info, but where does it get the new hostname from? Do I
need to change the actual server hostnames of my nodes? If I were to do
that then the hosts would not be accessible due to the fact that the
gluster storage subnet is isolated.
I guess I'm confused about what gdeploy does during a new HCI deployment.
I understand that you are now suppose to use hostnames that resolve to the
storage network subnet in the first step and then specify FQDNs for
management in the next step. Where do the FQDNs actually get used?
Can someone confirm if the hostname of oVirt host nodes should as shown by
the "#hostname" command should resolve to IPs on the gluster storage
network?

The reset-brick and replace-brick affects only one brick and notifies
the
gluster cluster that a new hostname:/brick_path is being used.
Of course, you need a hostname that resolves to the IP that is on the
storage network.
WARNING: Ensure that no heals are pending as the commands are wiping the
brick and data there is lost.

What does the reset brick option do and is it safe to do this on a live
system or do all VMs need to be brought down first? How does resetting the
brick fix the issue with gluster peers using the server hostnames which are
attached to IPs on the ovirtmanagement network?

Is there a way to fix this on a hci deployment which is already in
operation? I do have a separate gluster network which is chosen for
migration and gluster network but when I originally deployed I used just
one set of host names which resolve to management network subnet.
You will need to change the interface that's used by the bricks. You can
do this by using the "Reset brick" option, once the gluster management
network is set correctly on the storage interface from ovirt-engine
I appear to have a situation where gluster traffic may be going through
both networks in seeing what looks like gluster traffic on both the gluster
interface and ovirt management.

Thank you Simone for the clarifications.
I've redeployed with both management and storage FQDNs; now everything
seems to be in its place.
I only have a couple of questions:
1) In the Gluster deployment Wizard, section 1 (Hosts) and 2 (Additional
Hosts) are misleading; should be renamed in something like "Host
Configuration: Storage side" / "Host Configuration: Management side".
2) what is the real function of the "Gluster Network" cluster traffic
type? What it actually does?
Thanks,
Stefano.
