Description

When media is not set or not available via taxonomy, we generate error trace:

2016-08-05 12:28:16 [app] [W] Fetch TFTP boot files for mac52540028624f.lab.eng.rdu2.redhat.com task failed with the following error: undefined method `path' for nil:NilClass

We should catch for exceptions in the orchestration code and issue error.

History

#1 Updated by Lukas Zapletal almost 5 years ago

We need to check for StandardError in the setTFTPBootFiles method.

#2 Updated by Lukas Zapletal almost 5 years ago

When doing this, put an ERF entry on our wiki with explanation of the error.

#5 Updated by Dominic Cleal almost 5 years ago

  • Project changed from Foreman to Katello
  • Category deleted (Orchestration)

This is already implemented in boot_files_uri in #15439, but the stack trace above looks like the issue is introduced by Katello which is not deferring to the original boot_files_uri method containing the safety checks.

I'd suggest whatever checks are in Foreman should be applied to Katello, or it should call, not override, the original method.

Oh right, I had this feeling I was fixing this already! Thanks. Over to Katello folks! Easy one.

For the record, the required change is to run through these checks when overriding the method: https://github.com/theforeman/foreman/pull/3597/files
