The persistent volume (PV) lifecycle follows five phases: provision, bind, use, release, and reclaim. Each phase has behaviors that affect storage availability and data retention. Understanding the lifecycle helps you choose reclaim policies, troubleshoot binding failures, and prevent data loss.
PVs are resources in the cluster. Persistent volume claims (PVCs) are requests for those resources and also act as claim checks to the resource.
The interaction between PVs and PVCs has the following lifecycle.
