Question : Shrinkfile and backup log with truncate only do not shrink log

Hi,

The log file will not shrink in size.
I used the following commend (to no avail):
  CHECKPOINT
  GO
  DBCC shrinkfile('DBNAME', 1)
  GO
  BACKUP LOG CAM WITH TRUNCATE_ONLY
  GO
  DBCC shrinkfile('DBNAME', 1)
  GO

The dabase was imported from 2000 a few weeks ago.
It is using the "FULL" recovery model, since it is a high availability system.

When I run SP_LOCK, I see no locking transactions.

When I run the DBCC opentran, I see the following:
  Transaction information for database 'DBNAME'.
  Replicated Transaction Information:
          Oldest distributed LSN     : (0:0:0)
          Oldest non-distributed LSN : (145792:201:1)

But there is no replication on this database... And there hasn't been since I got here (1 year+).
I also ran the:
  EXEC sp_repldone @xactid = NULL, @xact_segno = NULL, @numtrans = 0,     @time = 0, @reset = 1
But I got the message:
  Msg 18757, Level 16, State 1, Procedure sp_repldone, Line 1
  Unable to execute procedure. The database is not published...

Any ideas?

You should look at http://support.microsoft.com/kb/907511/en-us
and remember that log files are circular.  If you have a 1 GB of log file, it will shrink it to the point in the log that is free to the end of the file.
