Question

An open-data team has one ReadWriteOnce PersistentVolume. What happens if two PVCs try to bind that same PV at once?

Accepted Answer

Only one PVC can bind the PV at a time; the second claim stays unbound until the volume is free. — One key, one lease. A single PV binds to one PVC; a second claim doesn’t get to share that lock just because it wants to.

Answer

Both PVCs bind simultaneously because RWO allows two writers across namespaces.

Answer

Kubernetes merges the two PVCs into a single claim named with a hash.

Answer

The second PVC automatically converts the PV access mode to ReadWriteMany.
