[ovirt-users] Dedicated NICs for gluster network

[Nicolas Ecarnot]

Hello,

[Here : oVirt 3.5.3, 3 x CentOS 7.0 hosts with replica-3 gluster SD on 
the hosts].

On the switchs, I have created a dedicated VLAN to isolate the glusterFS 
traffic, but I'm not using it yet.
I was thinking of creating a dedicated IP for each node's gluster NIC, 
and a DNS record by the way ("my_nodes_name_GL"), but I fear using this 
hostname or this ip in oVirt GUI host network interface tab, leading 
oVirt think this is a different host.

Not being sure this fear is clearly described, let's say :
- On each node, I create a second ip+(dns record in the soa) used by 
gluster, plugged on the correct VLAN
- in oVirt gui, in the host network setting tab, the interface will be 
seen, with its ip, but reverse-dns-related to a different hostname.
Here, I fear oVirt might check this reverse DNS and declare this NIC 
belongs to another host.

I would also prefer not use a reverse pointing to the name of the host 
management ip, as this is evil and I'm a good guy.

On your side, how do you cope with a dedicated storage network in case 
of storage+compute mixed hosts?
