Question

An open-data PVC requests an access mode the provisioner cannot offer, and binding fails. What rule explains the failure?

Accepted Answer

Requested PVC accessModes must be supported by the PersistentVolume or provisioner backend — You can’t order a “shared writable” pizza from a shop that only sells single slices—the backend has to support the access mode you ask for. If the PVC wants RWX and the disk type is RWO-only, binding fails. Modes aren’t decoration kubelet rewrites away.

Answer

Any accessModes string is accepted; kubelet converts unsupported modes at mount time

Answer

accessModes are cosmetic labels and never participate in PV/PVC binding

Answer

CSI ignores accessModes whenever allowVolumeExpansion is true
