[ovirt-users] Single Node oVirt and Gluster Hyperconverged
I have a question about this specific prerequisite-
* You must have at least 2 interfaces on the host, so that the frontend and backend
traffic can be separated out. Having only one network will cause the engine monitoring,
client traffic, gluster I/O traffic to all run together and interfere each other. To
segregate the backend network, the gluster cluster is formed using the backend network
addresses, and the nodes are added to the engine using the frontend network address.
>>You must have at least 2 interfaces on the host, so that the

me. You need at least 2 NICs.

you need to have the IPs in different subnets or can they be in the same subnet?
For reference, I was able to set this up with two IPs in the same subnet and it does seem
to work. However, I have noted some slowness issues while connecting storage domains
during startup and frequently get messages about needing to restart the HA agent. Usually
it seems after I try to restart services I can get the system to recognize the engine
storage domain and start the engine. I wonder if my problem is the fact that both my
front and backend IPs are in the same subnet? Thanks for your advice.
