The e2fsprogs-1.39 shipped with CentOS would not be useful since it
does not have extents support plus some other patches. So you should
install e2fsprogs from the clusterfs website.

We are currently working to remove the external dependency on db-4 and
replace it with tdb which is available in e2fsprogs-1.40 itself. Until
this work is finished, you can try installing an older version of db4.
