Capsule Sync fails with 'PLP0000: Importer indicated a failed response' error on Red Hat Satellite.

Solution Verified - Updated

Environment

  • Red Hat Satellite 6.4 and above.

Issue

  • During a capsule sync, the error PLP0000: Importer indicated a failed response is generated in /var/log/foreman/production.log on the Red Hat Satellite server.

  • The pulp.server.managers.repo.sync.sync task on the Satellite shows the following traceback:

      raise pulp_exceptions.PulpExecutionException(_('Importer indicated a failed response'))
  PulpExecutionException: Importer indicated a failed response

  • On the Capsule, under the /var/log/messages file, logging will indicate that an attempt to retrieve metadata from the Satellite resulted in a Not Found error.

Resolution

  • Refresh the affected Content View by re-publishing and selecting the Force Yum Metadata Regeneration checkbox option.

Root Cause

  • Broken symlinks in the pulp repository's filesystem structure caused the capsule to fail retrieve the metadata.

  • The cause of the broken symlinks is unknown, but it is currently suspected of happening during a Content View publish task.

Diagnostic Steps

  • The PLP0000: Importer indicated a failed response is a fairly generic error indicating that something went wrong. Since it occurred during a Capsule sync attempt, examining the Capsule logs during the time of failure yields more information.

  • In the /var/log/messages of the capsule, the following example shows that pulp attempted to retrieve the metadata for a specified repository, ultimately resulting in a "Not Found". The pulp importer then throws an IOError and raises the exception PulpExecutionException: Importer indicated a failed response which is reported by the Satellite.

  • Examining the "repodata" files under the repository's directory structure on the Satellite will show it not linked to a valid file.
