Unable to resume.| ## Explanation Database mirroring failed to redo a log record on the mirror. ### Possible Causes The most likely cause is that an add-file operation completed on the principal database but then failed on the mirror database because file names or directory structures differ on the principal server and mirror server. ## User Action Look in the [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] error log for the cause of this error. Try to resolve the cause and resume mirroring on the database. ## See Also [Troubleshoot Database Mirroring Configuration (SQL Server)](~/database-engine/database-mirroring/troubleshoot-database-mirroring-configuration-sql-server.md)
