Doc Type: Bug Fix
Doc Text:
Cause: error handling when communicating with Manila didn't account for all possible failures. Consequence: unexpected errors when talking to Manila would degrade the operator and thus the cluster. Fix: treat all failures to reach the Manila endpoint as a non fatal error Result: the Manila operator gets disabled instead of making the cluster degraded.

Description OpenShift BugZilla Robot 2021-09-07 14:25:22 UTC
+++ This bug was initially created as a clone of Bug #2001620 +++

Description of problem: It's possible that for one reason or another we're unable to reach the Manila endpoint. In the past we've tried to be smart and handled errors differently, if it's a 404, a 403, or other types of errors. The problem with this approach is that it's very easy to forget valid failure cases. We've had a recent example with proxy setting not correctly propagated to the Manila pod and degrading the cluster.

We should instead treat all failures to reach the Manila endpoint as a non fatal error and disable the Manila operator instead of making the cluster degraded.
