Description Jan Safranek 2021-08-02 15:41:15 UTC

We run e2e tests on a cluster with masters in 5 different zones, while workers only in 3 zones. Test "should schedule pods in the same zones as statically provisioned PVs" schedules a pod on a master, which then won't run.

We have a "<drop>" PR to skip the test: https://github.com/openshift/kubernetes/pull/870. 
Replace this <drop> patch with a proper fix upstream.


Idea: Use GetReadySchedulableNodes to get list of all schedulable and untainted nodes when considering zones where to provision a volume.
