8:13 a.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
Uuid: a95a9233-203d-4280-92b9-04217fa338d8
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
listening on ovirtmgmt, link-type EN10MB (Ethernet), capture size 262144 bytes

...
and no yet to the eth1 I dedicated to gluster:
[root@node1 ~]# tcpdump -i eth1 portrange 49152-49664
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth1, link-type EN10MB (Ethernet), capture size 262144 bytes
What am I missing here? What can I do to force the Gluster traffic to really flow on
dedicated Gluster network?
Thank you,
Stefano.
