VSC with SVM-DR / Snapshot cannot age due "database record owner"

Hey folks,

we have some troubles with Snapshots of VM-Datastore via VSC in combination with SVM-DR relationship of the NFS-Datastore.

Snapshots cannot be deleted as configured in the vsc backup job because some snapshots have an record-owner entry. 

CL1::*> snapshot show -volume ESXxx -fields owners,busy,record-owner,create-time
vserver volume      snapshot                         create-time              busy  owners record-owner

Due to this entry, we cannot delete the snapshot in VSC, SystemManager and CLI (*force should work, but the vsc will not know about the deletion).

We are looking for a way to delete the record-owner entry or to prevent the vm backup process (VSC+SVM-DR) to create snapshots with stuck Database record owner.

Is there anyone out there, who already had such an behaviour? And maybe an solution? 

Thanks for any hints,

regards,

Pat
