Users are encouraged to always run the latest version of e2fsprogs on their servers.
The Lustre-enhanced version of GNU tar is capable of backing up and restoring the Lustre layout for files. This requires that the user specify the --xattr option when backing up and restoring the files. The RHEL6.3 and derivative releases of GNU tar include Lustre specific enhancements, so the separate Lustre-enhanced GNU tar is not needed for those releases.
