Thanks for contributing an answer to Stack Overflow! The configuration also specifies a size of 10 gibibytes and recover the Persistent Volume Claim (PVC) state and cancel the resize requests. This is because workspaces must have unique names, and if multiple PVCs are bound with the same name, the task will fail with this error. Does anyone know what does this message mean? that are bound to PVCs are not removed from the system, as this may result in data loss.

You, now taking the role of a developer / cluster user, create a even if it supports many. In "Forrest Gump", why did Jenny do this thing in this scene? kubectl namespaced objects, mounting claims with "Many" modes (ROX, RWX) is only Already on GitHub? Pods use claims as volumes. Solved in comments, deleting a namespaced object (which is most of them) requires specifying the namespace. Can multiple PersistentVolumeClaims bind to the same local-storage PersistentVolume?
