Re: [Users] Multiple network interfaces on engine?
Thanks Michael, I'm still trying to get my head around this, but I can't see how I configure the networks on the engine? For nodes and AOI it's OK, but in my case I am running the engine as a separate server which is not a node and does not show up as a Host in the GUI. Or do I need to add the engine as a host in the GUI as well, to be able to configure it? - Ursprungligt meddelande - Från: Michael Pasternak mpast...@redhat.com Till: Rickard Kristiansson rick...@sanuksystems.com Kopia: users@ovirt.org Skickat: måndag, 23 sep 2013 12:21:40 Ämne: Re: [Users] Multiple network interfaces on engine?

Re: [Users] Multiple network interfaces on engine?
OK. Maybe I'm asking for something irrelevant, but to answer René's question; The use case is that there are two separate physical networks for general IP and storage IP, and Engine seems to require to be able to reach the NFS server to validate the connection when configuring mapping. So to be able to configure a NFS server, the Engine needs to be connected also to the storage network. It worked fine after manually tweaking the sysconfig/network-scripts, but this config was then shortly overridden by Engine discovering and trying to use the second NIC for bonding with ovirtmgmt. - Ursprungligt meddelande - Från: Michael Pasternak mpast...@redhat.com Till: Rickard Kristiansson rick...@sanuksystems.com, users@ovirt.org, Oved Ourfalli ov...@redhat.com Kopia: Ohad Levy ol...@redhat.com Skickat: måndag, 23 sep 2013 13:35:40 Ämne: Re: [Users] Multiple network interfaces on engine?

It looks like you have a bond defined somewhere and it looks like you have vdsm running on your engine server. Just looking at my two engine servers and none has more than one ip. The one in the test setup doesn't even have storage assigned and doesn't need it. It sends mount commands to the hosts which DO have a separate storage network. My engine hosts don't host the iso/export domains so don't need to be in the storage network. If you have the possibility, go back to a bare machine with NetworkManager turned off and network turned on. Make sure networking is working as expected, eth0=ip in managment, eth1= ip in storage. Install/setup ovirt-engine-setup, don't install vdsm (gets installed if you do allinone!) and things should 'just' work.

Re: [Users] Multiple network interfaces on engine?
is it possible that you have all-in-one installed and have both the engine and host on a same machine?

For nodes and AOI it's OK, but in my case I am running the engine as a separate server which is not a node and does not show up as a Host in the GUI. Or do I need to add the engine as a host in the GUI as well, to be able to configure it? IIUC your question, you have various options: 1. GUI 2. SDKs 3. CLI you need to create network in DC, attach it to cluster, attach to host NIC/s (if you want it to be atomic operation, i.e you expect connectivity loss during the operation/s, setupnetworks should be used, otherwise you can use attach-network dialogues in UI) *Från: *Michael Pasternak mpast...@redhat.com *Till: *Rickard Kristiansson rick...@sanuksystems.com *Kopia: *users@ovirt.org *Skickat: *måndag, 23 sep 2013 12:21:40 *Ämne: *Re: [Users] Multiple network interfaces on engine?

Re: [Users] Multiple network interfaces on engine?
OK, thanks. Then I'm happy with the explanations that it is supposed to work the way I initially expected.. That all operations are actually carried out on the nodes is good news, and should solve all worries. I'll go back and see what is actually going wrong on the engine and try to fix it. I'd love to reinstall the engine, but as I can't find any documentation on how to reliably move configs from one engine to another, and I was brave enough to already put ovirt into production with a number of hypervisors, I'm somewhat limited to what I can/dare to do. - Ursprungligt meddelande - I have also more than one interface in my Engine but never had this problem, I don't have a ovirtmgmt network on my Engine hosts thats not needed. I can understand the need for the engine server to have a nic/ip in the managment network AND a nic/ip in the storage network. I also have a separate access/public network and ilo network. It looks like you have a bond defined somewhere and it looks like you have vdsm running on your engine server. Just looking at my two engine servers and none has more than one ip.
