By default, data protection volumes are set to the grow_shrink autosize mode, which enables the volume to grow or shrink in response to the amount of used space. If volume autosize is not enabled for the snapmirror destination, consider enabling it and setting it to grow_shrink.

They used a surrogate cluster on source acting as a tertiary (A->C) of a cascade. Customer relocated the tertiary (A->C) to the DR site and attempted to reestablish replication (C->B). This failed with the not common snapshot error. The common snapshots were on the (A->C) cluster but the snapmirror transfer with mirrorallsnapshot did not transfer the common snapshot or daily snaps.
