Hi, I have two Exchange Server, ServerA and ServerB. I would like to copy DatabaseA from ServerB to ServerA. I used EMC to "add mailbox database copy" but found below error. I checked the databaseA.edb had been copied to ServerA. The log folder is empty. I checked the services of two Exchange Server, the Microsoft Exchange Search Indexer is running. 

Thank you!

Event ID: 2059
The required log file 5043358 for DatabaseA\ServerA is missing on the active copy. If you removed the log file, please replace it. If the log file is lost, the database copy will need to be reseeded using Update-MailboxDatabaseCopy.

Have you rebooted the two machines since then? You could also try restarting the Search' service. Is this a fresh copy your creating? Meaning, was there ever a copy on Server A?

So you created a DAG > Added Server B to the DAG with its mailbox database. You then went into EMC and added another database copy?I would restart search service on both machines. Then Open Exchange MAnagement Shell : Run Get-MailboxDatabaseCopyStatus *

 * Verify the above only shows one 'Copy' of your database. If it does (still in EMS) run Add-MailboxDatabaseCopy <Name of Database> -ServerToAdd <ServerA>

Please let me know what comes of the above.

Are all the Exchange services running or not?

Test-ServiceHealth

Running that cmdlet (EMS) on both servers should tell you.

Hi,

According to the error message, please ensure the Microsoft Exchange Search Service run correctly in Server B. We can restart it for testing.

Please run Get-MailboxDatabaseCopyStatus -Identity DatabaseA | FL to get status information about mailbox database copies. Besides, run Test-ReplicationHealth -Identity "ServerB" to voew continuous replication status information about mailbox database copies.
More details about those monitor methods for DAG, for your reference: https://technet.microsoft.com/en-us/library/dd351258(v=exchg.80).aspx
