the task, "Check the dns information provided by the virthost" fails

[Honza Pokorny]

During a devmode run against rdo cloud:

$ bash devmode.sh --no-gate --ovb

It looks like the connection to rdo-cloud is not quite fast enough.
Please try w/ https://review.openstack.org/#/c/471886/ which adjusts the ansible config and the ssh settings.

[Honza Pokorny (hpokorny)]

Even with the retries, the issue still occurs.

The dns server in the defaults is out of commission.
You'll need the dns servers specified in https://review.openstack.org/#/c/474781/

Also, ssh_args = -o ServerAliveInterval=30 is required if ssh is timing out.

[wes hayutin (weshayutin)]

This is an issue w/ rdo-cloud atm..

Everyone is either hitting timeouts or other ssh errors.

Examples:

ssh: connect to host localhost port 22: Connection refused\r\n", "unreachable": true

 UNREACHABLE! => {"changed": false, "msg": "Failed to connect to the host via ssh: Warning: Permanently added 'localhost' (ECDSA) to the list of known hosts.\r\nPermission denied (publickey,gssapi-keyex,gssapi-with-mic,password).\r\n", "unreachable": true}

fatal: [undercloud]: FAILED! => {"failed": true, "msg": "Timeout (12s) waiting for privilege escalation prompt: "}

[Bogdan Dobrelya (bogdando)]

hint: using the ansible.cfg with

[default]
timeout = 90

helps to mitigate those "Timeout (12s) waiting for privilege escalation prompt: "

The error you hit was related to the network, however there is also a bug sitting behind that task as well. It is resolved w/ https://review.openstack.org/#/c/478273/

[Ronelle Landy (rlandy)]

https://review.openstack.org/#/c/478273/ has merged.

We have a periodic job running now to check devmode on OVB.
With setting'ssh_args = -o ServerAliveInterval=30' in ansible.cfg, devmode on OVB has been passing since 07/01:

[Ronelle Landy (rlandy)]

Confirmed with honza that devmode on OVB is working now:
<honza> rlandy: yes, definitely working now
closing this out
