that would help reduce the skew. A constraint
is considered "Unsatisfiable" for an incoming

For example, in a 3-zone cluster, MaxSkew is set
to 1, and pods with the same labelSelector spread
as 3/1/1: | zone1 | zone2 | zone3 | | P P P | P | P |
If WhenUnsatisfiable is set to DoNotSchedule,
incoming pod can only be scheduled to zone2(zone3)

source, it will create a new volume based on the contents

dataSourceRef:
description: 'Specifies the object from which to populate
the volume with data, if a non-empty volume is desired.
This may be any local object from a non-empty API group
(non core object) or a PersistentVolumeClaim object. When
this field is specified, volume binding will only succeed
if the type of the specified object matches some installed
volume populator or dynamic provisioner. This field will
replace the functionality of the DataSource field and as
such if both fields are non-empty, they must have the same
value. For backwards compatibility, both fields (DataSource
and DataSourceRef) will be set to the same value automatically
if one of them is empty and the other is non-empty. There
are two important differences between DataSource and DataSourceRef:
* While DataSource only allows two specific types of objects,
DataSourceRef allows any non-core object, as well as PersistentVolumeClaim
objects. * While DataSource ignores disallowed values (dropping
them), DataSourceRef preserves all values, and generates
an error if a disallowed value is specified. (Alpha) Using
this field requires the AnyVolumeDataSource feature gate
to be enabled.'
