Found the issue, we have protocol auditing enabled, and the cluster does not allow for log rotation.  So in the 45 days of use, there were 10TB of logs created...  I'm trying to see if support has any implementation to automatically rotate the logs, as the information is sent to a CEE provider.  Thanks again for your help!!!
Been getting no where with support where we are seeing an 8-10TB discrepancy in free space between two identical clusters, we have approx. 20TB of data.  We replicate everything except for one folder which is 838GB with overhead in size.  On both sides we keep 30 days of snapshots, but we have had to pretty much delete all snapshots on the source to regain some free space.  Being told by support that you will see a difference in capacity, which I understand, but not so much...Has anyone seen similar issues?
