Re: [ovirt-users] Network instability after upgrade 3.6.0 -> 3.6.1

2015-12-29 Thread Jon Archer
Stefano,

I am currently experiencing the same issue. 2x nic lacp config at switch, mode 
4 bond at server with no connectivity. Interestingly I am able to ping the 
switch itself.

I haven't had time to investigate thoroughly but my first thought is an update 
somewhere.

Did you ever resolve and get back to mode=4?

Jon

My guess is that this is a consequence of your networking problems.

[ovirt-users] Network instability after upgrade 3.6.0 -> 3.6.1

2015-12-17 Thread Stefano Danzi

Hello,
I have one testing host (only one host) with self hosted engine and 2 VM 
(one linux and one windows).


After upgrade ovirt from 3.6.0 to 3.6.1 the network connection works 
discontinuously.
Every 10 minutes HA agent restart hosted engine VM because result down. 
But the machine is UP,

only the network stop to work for some minutes.
I activate global maintenace mode to prevent engine reboot. If I ssh to 
the hosted engine sometimes
the connection work and sometimes no.  Using VNC connection to engine I 
see that sometime VM reach external network

and sometimes no.
If I do a tcpdump on phisical ethernet interface I don't see any packet 
when network on vm don't work.

2015-12-17 Thread Stefano Danzi

I partially solve the problem.

My host machine has 2 network interfaces with a bond. The bond was 
configured with  mode=4 (802.3ad) and switch was configured in the same way.
If I remove one network cable the network become stable. With both 
cables attached the network is instable.


I removed the link aggregation configuration from switch and change the 
bond in mode=2 (balance-xor). Now the network are stable.
The strange thing is that previous configuration worked fine for one 
year... since the last upgrade.


Now ha-agent don't reboot the hosted-engine anymore, but I receive two 
emails from brocker evere 2/5 minutes.
First a mail with "ovirt-hosted-engine state transition 
StartState-ReinitializeFSM" and after "ovirt-hosted-engine state
