When cloning a PVC of 60GiB size, the system autofills the remote size to be 8192 PeB. This size cannot be changed in the UI before starting the clone.

CNV - 4.14.3

always

1.Create a VM with a PVC of 60Gib
2.Power off the VM
3.As a cluster admin, clone the 60GiB PVC (Storage -> PersistentVolumeClaims -> Kebab menu next to pvc

The system tries to clone the 60 GiB PVC as a 8192 PeB

A new pvc of the 60 GiB

This seems like the closed BZ 2177979.I will upload a screenshot of the UI.
Here is the yaml for the original pvc.
