The extend size I was referring to is not related to any ondisk size. It depends on the location the write() is issued to. Say you have a 100K sized file and you issue a write() at offset 1G. If the fs supports sparse files, it will allocate (and init) blocks only around the 1G location, leaving a hole in between. A non-sparsefile supporting fs, on the other hand, will need to allocate (and init) the entire space between 100K and 1G. _______________________________________________ Ocfs2-users mailing list Ocfs2-users@oss.oracle.com http://oss.oracle.com/mailman/listinfo/ocfs2-users
