Exchange 2010 Database Copy Failed with high Copy Queue Length and no log files

I recently noticed the following after creating an Exchange 2010 (SP2) Database Copy (Exchange DAG across two datacenters and two AD Sites):

·         DB Copy Status: Failed. Error: The required log file <nr> for <DB> is missing on the active copy
·         High Copy Queue Length
·         DB Copy (.edb file) was created but no log files

1.       Remove passive DB Copy
2.       Delete DB & log files from disk
3.       Force AD replication between AD Sites
4.       Dismount active database
5.       Delete all E0*.log files
6.       Mount database
7.       Create DB Copy
