This may be one of the unfortunate side-effects of allowing "pre-bound" volumes. We would like to deprecate this (unintentional) feature at some point. In your case, are you specifying the claim in the PV, or the PV in the claim? Please provide the yaml for PV and PVC. Assigning to jsafrane for further investigation. In current implementation, pre-binding volume to a claim (and claim to a volume) trumps everything, including label checks, size, access modes and storage class in future. User wants a specific volume/claim and he gets it. Erin, is this common understanding or should we do something about it. This is worked as expected. If a PV contains a ClaimRef, access and size should be ignored. Thanks, will udpate the test case re-open this bug according to https://bugzilla.redhat.com/show_bug.cgi?id=1366500#c4 Ok, per the two BZs the updated behavior is here: https://github.com/kubernetes/kubernetes/pull/30690 marking as 'post' while we backport & merge into openshift. Need origin PR... This is passed on openshift v3.3.0.24-dirty kubernetes v1.3.0+507d3a7 etcd 2.3.0+git After create pv and pvc using https://bugzilla.redhat.com/show_bug.cgi?id=1360171#c0 pv is avaiable and pvc is pending Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
