Description Goutham Pacha Ravi 2019-07-31 17:00:01 UTC

+++ This bug was initially created as a clone of Bug #1724622 +++

Description of problem:
This failure was found on an RHOSP platform with TripleO deployed configuration, a gist of which is:

1) Setup a mod-wsgi proxy for the manila-api with Apache
2) Expose the manila endpoints via haproxy
3) Run manila microversion tempest tests

manila_tempest_tests.tests.api.test_microversions.MicroversionsTest.test_microversions_v1_no_version[api,positive] (from manila)

Comment 2 Goutham Pacha Ravi 2019-09-16 21:34:54 UTC

At present, we do not have a plan to pursue a fix for this issue in OSP 14. The issue has been addressed in OSP 13 and OSP 15, and future releases. If you use OSP 14, and feel that this issue is affecting you, please feel free to skip these API-only tests (manila_tempest_tests.tests.api.test_microversions.MicroversionsTest) when running manila tempest tests.  If you disagree, please feel free to re-open this bug.
