RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 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 "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". 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 "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-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.

Comment 2 Petr Vobornik 2017-04-07 10:14:08 UTC 
ipa host-add checks if host is resolvable via DNS. In this case the resolution failed. It indicates a configuration problem.

SERVFAIL means error 2:  
    Server failure - The name server was unable to process this 
                     query due to a problem with the name server.

https://tools.ietf.org/html/rfc1035

What is your DNS configuration?
  What zones does the IPA server manage?
  Did you set any DNS forwarders during server installation?
  Did you set any forward zones?

Some info might be in
  # journalctl -u named-pkcs11.service

If you don't care and it is just for testing, then workaround is to use --force option.
Comment 3 Martijn ten Heuvel 2017-04-07 10:55:35 UTC 
The issue is not that the command failed, but the typo in the error, it says "anwered" instead of "answered".
Comment 4 Martin Bašti 2017-04-07 11:08:28 UTC 
This is bug in DNS python, it is already fixed upstream.

To fix this we have to backport patch to RHEL.

Comment 5 Petr Vobornik 2017-04-13 15:59:27 UTC 
Per assessment in comment 4, moving to python-dns component.
Comment 6 Charalampos Stratakis 2017-04-13 16:09:15 UTC 
As we are currently way past the devel phase, asking the respective QE owner if the fix can be included at the current erratum of python-dns for RHEL 7.4
