Volume snapmirror available space difference

[Julien_Mos]

Hi,

I wonder how is that possible that my source and destination volume have not the same available space ?

It's okey to have some GB, i mean the synchronisation has to be execute, but when we talk about hundred of GB is that normal ?

Please attach the screenshot of the difference, it helps.

In the mean time - Could you also give us the output of how the 'storage efficiency' is configured for the source/dest. If the storage efficiency configuration on the destination volume does not match source volume, it will result in loss of storage efficiency on transfer. In this case, destination volume shows higher disk usage than source volume. Also, mention the ONTAP version.

Effiency is enable on the source volume, but not on the dest. (that what i red in the documentation of Netapp).

Ontap version : Ontap 9.6P2

ok. That could explain the difference in space.
