KB4497230 - FIX: Fail to join the secondary replica if the database has a defunct filegroup in SQL Server 2014, 2016 and 2017

Symptoms

Consider the following scenario:

  • You have a database with a defunct filegroup which you are trying to add to an Always On availability group (AG) in Microsoft SQL Server 2014, 2016 and 2017.

  • You are able to add the database to the primary replica and restore the full and log backups with NORECOVERY on the secondary replica without issue.

In this scenario, when you try to join the database to the availability group on the secondary replica with ALTER DATABASE <DatabaseName> SET HADR AVAILABILITY GROUP = <AGName> or use automatic seeding to configure secondary replica, you notice that errors 17207 and 5120 are reported for the data file in the defunct filegroup:

## spid##     Starting up database 'DatabaseName'.

## spid##     Error: 17207, Severity: 16, State: 1.

## spid##     FileMgr::StartSecondaryDataFiles: Operating system error 2(The system cannot find the file specified.) occurred while creating or opening file 'FilePath'. Diagnose and correct the operating system error, and retry the operation.

## spid##     Error: 5120, Severity: 16, State: 5.

## spid##     Unable to open the physical file "FilePath". Operating system error 2: "2(The system cannot find the file specified.)".

You will also see the database go into Not Synchronizing/Recovery Pending mode on the secondary replica after the ALTER DATABASE command is executed.
