           Summary: Database locking due to write contention between CTR
                    sql connection and tier migrator sql connection
           Product: GlusterFS
           Version: mainline
         Component: tiering

Description of problem:
The DB on the brick is been accessed by CTR, for write and
tier migrator, for read and write. The write from tier migrator is reseting
the heat counters after a cycle. Since we are using sqlite, two connections
trying to write would cause a db lock contention. As a result CTR used to fail
to update the db.
