Updated scrub packages that fix one bug and add one enhancement are now available for Red Hat Enterprise Linux 6.
Scrub writes patterns on files or disk devices to make retrieving the data more difficult. It is a program for erasing disks.

Bug Fix

BZ#903890
When the "scrub -X" command was executed, it rewrote free space on given disk partition but failed to remove files created during this process. As a consequence, the respective file system remained full after this process. With this update, the newly created files are removed, and the file system regains the free space.
In addition, this update adds the following

Enhancement

BZ#907173
With this update, the new "-E" option has been added to scrub, which has the ability to scrub only used blocks of a sparse file. This option is especially useful in combination with large sparse files, as it skips the holes in the sparse file. Nevertheless, use this option with caution, as the result may not be compliant with cited standards and information about the actual on-disk data allocation may leak since only the allocated parts will be scrubbed.
Users of scrub are advised to upgrade to these updated packages, which fix this bug and add this enhancement.
