Issue

On a PV using an ontap-nas backend with a snapshot reserve set, creating a Snapshot from Kubernetes/Openshift causes the following error:

In version 21.07.0:

csi.trident.netapp.io_trident-csi-<UUID> failed to provision volume with StorageClass "storage-class-nas-snap-reserve":

error getting handle for DataSource Type VolumeSnapshot by Name <SNAP_NAME>:

requested volume size 10737418240 is less than the size 17895698432 for the source snapshot <SNAP_NAME>

In version 21.07.1:

Failed to check and update snapshot content: error updating status for volume snapshot content snapcontent-<UUID>:
