Exchange 2013: Unable to Create A Copy of the Database

Exchange 2013: Unable to Create A Copy of the Database

I was working on the issue where someone messed up the database. Only 1^st copy was mounted and other copies were not healthy.

Environment:

3 data center expanded DAG

2 Data center has Exchange servers

1 Data Center has FSW

Only one data center is internet facing.

Issue:

While creating a copy of the database on the 2^nd server, we got the following errors.

First Error

The seeding operation failed. Error: An error occurred while performing the seed operation. Error: Failed to notify source server “server fqdn ” about the local truncation point. Hresult: 0xc8000713. Error: Unable to find the file.

2^nd error

Failed to open a log truncation context to source server. Hresult: 0xc7ff1004. Error: Error returned from an ESE function call (-1305).

Resolution:

This is the issue with the old logs folder which was not in the sync.

For the 1^st error.

-Login to the source server

-Remove the 2^nd copy of the database

-Dismount the database

-Verify database is clean shutdown by running the command eseutil /mh driveletter:\database\database.edb

-Now rename the logs file folder to logs old.

-Mount the database

-Now the 1^st issue will be fixed.

For the 2^nd error.

-Login to the destination server where we are creating the 2^nd copy

-Now rename the logs and database file folder by adding old prefix.

-Add the 2^nd database copy.

-Now the 2nd issue will be fixed.

This environment was not backed up so there was a time when circular logging was enabled then disabled. After this one of the administrator messed up the database copies while expanding the C drive.

Conclusion:

This most important thing is to remember the error and its code because error will not clearly tell you the cause of the issue.

Next important thing is to take all precaution even if the environment is not in production.
