Non-Operational state because management interfaces down
<html><bodyHi, I have 2-node ovirt "cluster".

<html><bodyHi, I setup it via oVirt. The problem is that there is no link detected on the real interfaces for management (ovirtmgmt is UP but NO-CARRIER). If I add another interface (with link detected) to the bond (temporarily as I need it for backup) it's working properly. Cheers, Luf Demeter Tibor píše v Pá 14. 11. 2014 v 12:42 +0100:
Hi,
Did you set your bond devices and IP addresses via ovirt's network management, or by hand on the nodes?
In my experiences you need to set up ip addresses on the node's network interface via ovirt' management, because it won't working.

Hi Luf, Apologies, I probably don't understand the details of your L2 toplogy; how come when you turn off one host it affects the link state of of the other one's interfaces?... Yours, Lior. On 14/11/14 11:43, Finstrle, Ludek wrote:

Hi Lior, If I'm not mistaken, on Luf's topology, there is no switch on the management bond (bond0) - just a cross or regular eth cable connecting physical interfaces on both nodes. So when one node is powered down, there is no link detected on the other node. Regards, On Mon, Nov 17, 2014 at 12:02 PM, Lior Vernia <lvernia@redhat.com> wrote:

Hey, Thanks, so how come node2 moves to non-operational state rather than non-responsive (i.e. how come it's reachable from the engine)? The IP address via which it was installed, belongs to which network interface? bond1 which is used for data? Lior. On 18/11/14 12:17, Finstrle, Ludek wrote:

So when you take node1 down and node2's management interface goes down, how come the engine is still able to communicate with node2? Is the hostname also resolved to the data IP?

switch0 -----\ /-----\ /----- switch0 node1 node2 switch1 -----/ \-----/ \----- switch1
I setup everything as I want/expect but I hit one problem and I don't know how to fix it. The problem is when I switch off one of
for maintenance (node01.ovirt in this case). I get in ovirt engine this message:
Host node02.ovirt moved to Non-Operational state because interfaces which are down are needed by required networks in the current cluster: 'bond0 (ovirtmgmt)'.
Do you have any idea how to avoid it? I can't change
architecture as I don't have 10Gb switch.
BTW it's the same as if I want to start with only 1 node and separated data and mgmt networks:
switch ----- host --(not connected iface for mgmt as I don't need it)
Thanks,
Luf

Thanks, so how come node2 moves to non-operational state rather than non-responsive (i.e. how come it's reachable from the engine)? The IP address via which it was installed, belongs to which network interface? bond1 which is used for data?

Hi,
yes that's exactly what I tried to describe. Thanks Ekin. There is no switch between 2 hosts/nodes (for ovirtmgmt network). It's similar to situation when I tried just one host/node and put the ovirtmgmt network to not connected network interface (will connect it once we buy second host).

Hi Lior,
If I'm not mistaken, on Luf's topology, there is no switch on the management bond (bond0) - just a cross or regular eth cable connecting physical interfaces on both nodes. So when one node is powered down, there is no link detected on the other node.

Hi Luf, Let me have a think about it and I'll get back to you on whether there's a workaround or something needs to be enhanced in the engine logic. Thanks for bringing this up! Yours, Lior. On 20/11/14 15:11, Finstrle, Ludek wrote:
