Re: [ovirt-users] Non-Operational state because management interfaces down

2014-11-23 Thread Lior Vernia 
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.

It's not exact description of the situation.

1) both nodes up => everything is working properly
2) second node power off
3) first node still have interfaces up (ovirtmgmt -> ens1f0 just without
link detected) => first node is switched into Non-Operational mode
(there should be at least some switch if I require link detected)
4) ping is working correctly over ovirtmgmt (checked via tcpdump)
between remaining node and hosted engine running on that node

I switch back to the problematic situation and ensure I'm not saying
misleading information (ens1f0 is network interface for ovirtmgmt):
ovirtmgmt: flags=4163  mtu 9000
ens1f0: flags=4099  mtu 9000
# ethtool ens1f0

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?

Re: [ovirt-users] Non-Operational state because management interfaces down

2014-11-17 Thread Ekin Meroğlu 
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,

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.

Re: [ovirt-users] Non-Operational state because management interfaces down

2014-11-14 Thread Demeter Tibor 
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.
