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