Alex,

I haven't run into any issues with ovirt-ha-agent. I'm adding Simone who may have a better idea of what could be causing the problem. Could you provide any logs you have available from that deployment? Also, could you please run "journalctl -u ovirt-ha-agent" on that host and provide the output?

Thanks!

Hi Philip,

I finally was not able to complete it.
The ovirt ha agent at host was not starting for some reason.
It could be because I ran a hosted-engine-cleanup earlier.
So I need to repeat from scratch to be able to reproduce/verify.

I overcame this with:

run at host:

/usr/sbin/ovirt-hosted-engine-cleanup

Redeployed then engine
engine-setup

This time was ok.

Thanx,

Hi,

Thanx for the feedback.

getent ahostsv4 v0.mydomain

gives:

172.16.30.10    STREAM v0
172.16.30.10    DGRAM 
172.16.30.10    RAW   

which means that

getent ahostsv4 v0.mydomain | grep v0.mydomain

gives null

I overcame this by using the flag --noansible to proceed with the python way and it did succeed.

Now I am stuck at engine-setup create CA step. It never finishes and I see several errors at setup log (grep -iE 'error|fail' ):

I selected to autoconfigure the DB but seems that some auth issue is being logged for DB account of engine.

Any ideas on this?
I can share more logs if needed.

Thanx,
Alex

Hi Alex,

I believe the lines below from the deploy log point to the issue. I bolded the important parts. It looks like it was unable to resolve the FQDN for the host. What output and return code do you get when you run "getent ahostsv4 v0.mydomain | grep v0.mydomain" on that machine?

Additionally, work is underway to make the logs easier to read and more useful so that troubleshooting issues like this won't be as difficult in the future. I'm sorry for any frustration it's caused and appreciate you reaching out to work through the issue.

Hi all,

I am trying to setup ovirt 4.2 self hosted with 3 nodes.

I have done several 4.1 installations without issues. Now at 4.2 I get:

[ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "Unable to resolve address\n"}
[ ERROR ] Failed to execute stage 'Closing up': Failed executing ansible-playbook

I am running:

hosted-engine --deploy --config-append=/root/ovirt/storage.conf

Checking the log doesn't give an easy reference of the issue. Seems to be related with DNS but I can confirm that the host can resolve the engine FQDN from /etc/hosts or from the DNS server.

Any ideas?

Thanx,
Alex
