sys.master_files catalog view for TLOG growth is not updated on an AG secondary
When a database is a part of an AvailabilityGroup and you adjust the filegrowth setting for the transaction log it will update the meta data in the sys.database_files catalog view, however the sys.master_files catalog view on the AG secondaries will not be updated, and will still reflect the incorrect information. This could lead to incorrect settings being applied on AG failover.
This is a similar bug to https://support.microsoft.com/en-us/kb/2855755
This only applies to transaction log growth settings. Database file settings are correctly reflected on the secondary servers.
