Catalog compilation failed sometimes

[Vyacheslav Struk]

Catalog compilation fails with:

Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Could not autoload puppet/type/vs_port: Could not autoload puppet/provider/vs_port/ovs_redhat_el6: Could not find parent provider ovs_redhat of ovs_redhat_el6 on node <fqdn here>
Warning: Not using cache on failed catalog
Error: Could not retrieve catalog; skipping run

Sometimes puppet run ends-up successfully with just the same config, so it looks like a kind of race condition.
Both ovs_redhat_el6.rb and ovs_redhat.rb are present on a client and they are equal to server's files.
Puppet version is 3.6.2, module is from a master branch.

I am also experiencing the the same behaviour listed here. I am running on RHEL7 with 2 physical NICs bonded with OVS, and a bridge on top. The module works fine on RHEL6 with the same configuration, though not in RHEL7. Puppet agent and master are 3.8.1

I am using the puppet-vswitch master branch.

I have had the catalog compile successfully without changing any other code, the vast majority of the time though indicates the above failure.

I got the same issue on Fedora 22.

Hi all
Just wanted to add some more details of my environment to assist with anyone looking at this bug.

Hi all,

Hacking the ovs_redhat_el6.rb file as referenced here https://bugzilla.redhat.com/show_bug.cgi?id=1234042 fixes the issue

The changes required are:
modules/vswitch/lib/puppet/provider/vs_port$ diff /tmp/upstream_ovs_redhat_el6.rb ovs_redhat_el6.rb
0a1
> require File.expand_path(File.join(File.dirname(__FILE__), '.','ovs_redhat.rb'))

    Add require ovs_redhat.rb to ovs_redhat_el6.rb

    This change adds an explicit require of ovs_redhat.rb to the
    ovs_redhat_el6 provider to address possible compilation errors when
    the ovs_redhat provider was not loaded before the el6 version.
