Hi All,

Sorry didn't particpate discussion. Got pretty big issue with the cloud
yesterday. Very intersting one.
I have 2 networks with 2 dedicated VR (not VPC). One of the netowork with
default gateway, the second one just for internal interconnect between VMs.
Both network are IsolatedWithNoSNAT service, basically only DHCP. Both
network started. I started fire-up VMs and got default gateway on the
second NIC (it's configured to be on the first). Doing some troubleshooting
on it i found that default gateway was overwitten when second interface was
activating. From my understanding VR of the network not designated to be
"default" should not provide DHCP option "router", but it did.
More over it provided wrong default gateway. In my configuration default
gateway points to device in the reserved IP range (external router), but VR
is pushed own IP address as default gw, so network was completely down.
Here is some numbers

network 1 - 10.1.12.0/24 range 10.1.12.1-240, default gw 10.1.12.254
network 2 - 10.1.22.0/24 range 10.1.22.1-240, default gw 10.1.22.254 (i
have to specify it here, but i really don't need it, more over that ip is
down)

NIC1 on all VMs in network1, NIC1 is default
NIC2 on all VMs in network2

But i got default gw from network2, and it was 10.1.22.1, which is not in
configuration at all.

That is very confusing. I wasn't able to fix that issue, so i removed
network2 completely.

Configuration above was working with 4.5 and 4.4, so it points me that
there is definetely something wrong with 4.6 system VM image.

That solution to increase time-out rather work-arround then real fix for
the problem. There is no way that router is booting for 4-5 minutes.
 

The routers from Daniel work when we bumped global setting
router.aggregation.command.each.timeout to 20 or higher. You may need to
upgrade to 4.7.1 for that to work, but that's a good thing to do anyway
because it has a load of fixes over 4.6. The upgrade is quick and
painless.

For the record, it doesn't have to do with the template. Be happy we
reuse it, makes upgrading way easier.

Regards, Remi

4.7.1 also affected.
All versions use 4.6 templates.

P.S.: would it be usefull to move discussion to devs list. Looks like
it's
pretty big issue.

Hi!

After upgrading from 4.5.2 to 4.6.2, I also face this issue. We use
both
KVM and XenServer. Any stable workaround for this?

Thanx

Martin

Betreff: Re: upgrading 4.5.2 -> 4.6.0 virtualrouter upgrade timeout

Hello guys,

I've just upgraded to 4.6.2 and have similar issues with three virtual
routers out of 22 in total. They are all failing exactly the same way
as
described here.

Has anyone found a permanent workaround for this issue?

Thanks

Andrei

Does anybody else experiemce problems due to (very) slow deployment of
VRs?

Update / FYI:
After faking the particular VRu in sql, I tried to restart that
network, and it always fails. To me it looks like the
update_config.py - which takes almost all cpu ressources - runs way
longer any watchdog will accept.

I'm able to mitigate that by very nasty workarounds:
a) start the router
b) wait until its provisioned
c) restart cloudstack-management
d)  update vm_instance
set state='Running',
power_state='PowerOn' where name = 'r-XXX-VM';
e) once: update domain_router
set template_version="Cloudstack Release 4.6.0 Wed Nov 4 08:22:47 UTC
2015", scripts_version="546c9e7ac38e0aa16ecc498899dac8e2"
where id=XXX;
f) wait until update_config.py finishes (for me thats about 15
minutes)

Since I expect the need for VR restarts in the future, this behaviour
is somehow unsatisfying. It needs a lot of errorprone intervention.

I'm quite unsure if it's introduced with the update or the particular
VR just has simply not been restarted after getting configured with
lots of ips and rules.

Hi List!

After upgrading from 4.5.2 to 4.6.0 I faced a problem with one
virtualrouter. This particular VR has about 10 IPs w/ LB and FW
rules
defined. During the upgrade process, and after about 4-5 minutes a
watchdog kicks in and kills the respective VR due to no response.

So far I didn't find any timeout value in the global settings.
Temporarily setting network.router.EnableServiceMonitoring to false
doesn't change the behaviour.

Any help, how to mitigate that nasty timeout would be really
appreciated :)

cheers,

Stephan
