Synopsis
svnadmin list-dblogs REPOS_PATH
Description
Berkeley DB creates logs of all changes to the
        repository, which allow it to recover in the face of
        catastrophe.  Unless you enable
        DB_LOG_AUTOREMOVE, the logfiles
        accumulate, although most are no longer used and can be
        deleted to reclaim disk space.  See the section called “Managing Disk Space” for more
        information.
