3:13 p.m.
Hi,
I've deployed an oVirt HC starting with latest oVirt Node 4.3.6; this is my simple
network plan (FQDNs only resolves the front-end addresses):
front-end back-end
engine.ovirt 192.168.110.10
node1.ovirt 192.168.110.11 192.168.210.11
node2.ovirt 192.168.110.12 192.168.210.12
node3.ovirt 192.168.110.13 192.168.210.13
at the end I followed the RHHI-V 1.6 Deployment Guide where, at chapter 9 [1], it suggests
to create a logical network for Gluster traffic. Now I can see, indeed, back-end addresses
added in the address pool:
[root@node1 ~]# gluster peer status
Number of Peers: 2
Hostname: node3.ovirt
Uuid: 3fe33e8b-d073-4d7a-8bda-441c42317c92
State: Peer in Cluster (Connected)
Other names:
192.168.210.13
Hostname: node2.ovirt

State: Peer in Cluster (Connected)
Other names:
192.168.210.12
The problem is that the Gluster traffic seems still to flow on the management interfaces:
[root@node1 ~]# tcpdump -i ovirtmgmt portrange 49152-49664
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

The storage traffic allocation over multiple subnets is implicitly set by
name resolution and routing rules.
Please use two distinct hostnames for each host: the first one should
resolve only as an address on the management network and the second one as
an address on the storage network.
In the cockpit wizard for the hyperconverged deployment you will be
prompted twice about the name of the three hosts: on the first tab (named

New subject: [oVirt HC] Gluster traffic still flows on mgmt even after choosing a different Gluster nw
This is an interesting topic, I've had a 3 node HCI cluster configured the
same way and now I'm questioning whether or not my gluster traffic has been
using my gig network instead of my 10gig network on separate subnet.

New subject: [oVirt HC] Gluster traffic still flows on mgmt even after choosing a different Gluster nw
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.

New subject: [oVirt HC] Gluster traffic still flows on mgmt even after choosing a different Gluster nw
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.
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.

New subject: [oVirt HC] Gluster traffic still flows on mgmt even after choosing a different Gluster nw
I had originally setup my cluster following this older guide at
https://blogs.ovirt.org/2018/02/up-and-running-with-ovirt-4-2-and-gluster...
and
the fqdn steps did not exist at that time. After deployment I then followed
steps to add gluster network and set that network as storage and
migration. What is the difference between what I did and the new method
gdeploy uses? If my gluster config is using hostnames on the management
network subnet but the gluster network is set for gluster and migration
traffic what happens?

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

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?
