This issue occurs when a volume in Ready state is moved across storage pools.

Let us say there is a data volume, volume0 in Ready state in a cluster scope 
primary storage primary0.
Now, when an operation is attempted to attach this volume to a vm in another 
cluster, the volume is moved to the new cluster and the asking size is zero at 
this time.

you can observe logs like below with asking size 0 in the management server 
logs.
