I'm currently working with an instance of FIM where the FIMSynchronizationService database has grown to >200Gb and occupied all available disk space so that the sync service will no longer run. The reasons why this occurred are still being investigated but in the meantime I need to get this database down to a reasonable size so that I can restore at least some functionality. I can't simply perform a shrink operation because SQL Manager reports 0Mb free space in the database itself. The transaction log is much smaller (about the expected size).
Short of detaching the database, moving it to a different/new partition and re-attaching (which will be difficult in the specific context) or reinstalling the sync service, are there any T-SQL commands that might help to free up some space so that a shrink operation will work? PowerShell?
All suggestions appreciated!
