[ovirt-users] unable to add host in oVirt4.2
Hi When I add additional node with the version4.2 in the engine , getting the error " Host has no default route." though the node has the default gateway, below are the logs, Can you please help on the same? https://pastebin.com/sDyVkvVY Thanks, Nagaraju ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/site/privacy-policy/ oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/OR7VHK3MMZCKPHAZRFL2OUP537EUJRKA/
Re: [ovirt-users] Unable to add host to cluster after network
Hi Stack, Indeed this is a bug in the engine. We have opened a case [1] and are working to fix it on 4.2 ASAP Thanks for posting...

Confirmed. Setting the second network to 'not required' did not break the loop. I hard powered off the box, let ovirt set it as down (thus breaking the loop), then powered it back on. The loop continued (at least twice anyway - takes roughly 5 minutes for a loop). > > I haven't tried deleting the second network yet. Let me try that before > I rebuild to test the first point. Confirmed. Same thing as above only this time I deleted every network but ovirtmgmt. Again, went through 2 full loops without resolving. I am going to do a fresh rebuild and test by having the second network set to 'not required' before adding a second host. ~Stack~ signature.asc Description: OpenPGP digital signature ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Setting the second network to 'not-required' does not seem to break my hosts out of their infinite loop. I haven't tried deleting the second network yet. Let me try that before I rebuild to test the first point. Thank you for your feedback.

Re: [ovirt-users] Unable to add host to cluster after network
Hi Stack,
I read through your ordeal and I would like to post a few comments:
- When I try to reproduce your scenario with the second network set to
'not required' before on-boarding the second host, it is processed and set
to 'up' by the engine without any hiccups or any errors in the log.
- On the other hand, if the network is 'required' the scenario
reproduces, but on my setup it can be resolved: initially the second
network is proclaimed missing and the host becomes non-operational, with
its interfaces disappearing from the engine as you reported. But if the
second network is rendered 'not-required' or even deleted for that matter
from the engine, engine succeeds in reconnecting to the second host within
a couple of minutes, and the host gains 'up' status.

[ovirt-users] Unable to add host to cluster after network
Greetings,
After a few days of trial, error, and madness - I *think* I found the
source of my problem. Or at least I can now replicate it reliably. These
are the basics of my speed-run-to-test-failures setup.
Fresh minimal install of Scientific Linux 7.4 on a physical host for my
engine. Add the 4.2 repo and run engine-setup - just blast through the
defaults. Configure it with default DC and cluster.
Fresh minimal install of Scientific Linux 7.4 on node1 - configure only
the primary network card. Add the ovirt repo.
Add the host into cluster. Provisions just fine. Life is good.
Now here is where things split.
Scenario 1: build node2 same as node 1 configuring only the primary
network card and add it as a host. Provisions just fine. Life is good.
Scenario 2: Configure a second network. In my case a BMC/IPMI network.
Doesn't matter if it is required or not - both will cause failures
however the errors are slightly more evident with required. Make sure
the network is assigned to your node1 and is properly assigned an IP and
configured in the up state. Now build node2 same as before with only the
primary network configured and add it as a host.
Failure followed by infinite loop of setting it into Non-Operational!
The pop-up gives you some crap about "Host has no default route." but
that is 100% a red-herring.
Dig a little deeper and you get a message like this:
"node2 does not comply with the cluster Default networks, the following
networks are missing on host: 'ovirtmgmt'"
Ah. That's a bit more relevant, but why can't it configure it? Or at
least get to the point where it asks me "Hey, networking is a bit off -
do you want to configure that now?" That would be nice...
Fortunately the troubleshooting guide has something about that!
https://www.ovirt.org/documentation/how-to/troubleshooting/troubleshooting/
Unfortunately, it doesn't do anything to help. Even after doing these
steps, the loop just keeps going...nothing changes.
https://www.ovirt.org/develop/developer-guide/vdsm/installing-vdsm-from-rpm/
Scratch it all and completely rebuild AGAIN for...
Scenario 3: Configure a second network (BMC) and assign it to node1 just
like before. Build out node2 same as node1 but this time add in the
EXACT SAME NETWORK CONFIGURATION THAT IS WORKING ON NODE1 - ALL of the
ifcfg-* files (but update the IP address to correct host, obviously).
Now add it as a host.
Doh! Same error. :-/
OK fine. Let's really get into it. First off, the networking page for
the host is blank. It never pulls back the network cards so you can't
actually make changes via the web page. Nor can you assign networks. So
the web interface doesn't help at all.
Let's look at the engine log instead.
