[Ocfs2-users] Zero allocated blocks for nonempty file

[Sérgio Surkamp]

Hi.

I *suppose* its the inline-data feature, as it's permit the allocation
of small files and directories inside the inode itself.

From mkfs.ocfs2 man page:

                   inline-data
                          Enable  inline-data  support.  If  this
                   feature  is turned on, OCFS2 will store small files
                   and directo- ries  inside  the inode block. Data is
                   transparently moved out to an extent when it no
                   longer fits inside the inode block. In some cases,
                   this can also make a positive impact on  cold-cache
                   directory  and  file operations.

Regards,
Sérgio
