Last modified: 2017-08-16 15:51 EDT
Description of problem: PVs are dynamically provisioned with incorrect/inaccurate AccessModes Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Create a PVC asking for RWM AccessModes from a provisioner that can only do RWO (e.g. AWS EBS) 2. PV is created with RWM AccessModes 3. PV can't be used as RWM because it's an AWS EBS disk. Actual results: PV is created with incorrect AccessModes Expected results: PV is not created with incorrect AccessModes, provisioning should fail
