Red Hat Satellite engineering is moving the tracking of its product development work on Satellite to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "Satellite project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs will be migrated starting at the end of May. If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:

When provisioning a host with discovery if the host's subnet does not have a tftp proxy configured the discovered host will reboot and go back into the discovery mode.  Foreman should be able to recognize this situation and at least warn the user that this is not configured.  

I'm not positive if there is even a use case for the tftp proxy to not be associated to the subnet in this sceanrio, so we may want to block the discovery provisioning attempt if not.

At least one customer has hit this.


Version-Release number of selected component (if applicable):
6.1.4

How reproducible:
Always

Steps to Reproduce:
1.  Configure pxe discovery but do not associate the subnet with a tftp proxy/capsule
2. boot a system on that subnet
3. attempt to provision it

Actual results:
System reboots and goes back into discover

Expected results:
At least a warning is given to inform the user the tftp proxy is not configured on the subnet.


Additional info:

Created redmine issue http://projects.theforeman.org/issues/12705 from this bug

Well, if you don't have TFTP set, no provisioning will be orchestrated. That has nothing to do with Discovery :-)

I am unlikely to give this a priority as plugins are not able to do stuff like UI warnings without Deface gem. But I could issue a Flash warning message during provisioning, this will only work with one host provisioning tho. If you can help me reviewing and testing the patch, let me know.

Moving to POST since upstream bug http://projects.theforeman.org/issues/12705 has been closed

Upstream bug was mis-closed.

Guys, this is trivial thing that does not need to be tracked here, we have an upstream issue, I am unlikely to work on that soon.
