I have found the following error during report server configuration in TFS 2013. How can I solve this?
An error occurred within the report server database. This may be due to a connection failure, timeout or low disk condition within the database. (rsReportServerDatabaseError)
Database ID 6, Page (1:179) is marked RestorePending, which may indicate disk corruption. To recover from this state, perform a restore.
It looks like your database has gone corrupt during a restore action or failed to recover from a disk failure.
You'll need to check the SQL server that's hosting your TFS databases and ensure that it has enough free space, that its disks are in a healthy state and then either restore the analysis and warehouse databases or rebuild the warehouse using the TFS Administration Console.
Make sure you safeguard the last successful backup of your TFS environment on another disk or preferably system before trying to rebuild or restore. Such actions tend to cause massive disk IO and can further degrade the underlying disk.
