'lookup-unhashed' option of distribute should be 'auto' by default.
* Added 'auto' option, older boolean options works as they used to. * This option should make 'create' rate faster, also handles self-healing of linkfile properly in case of scaling to more servers or filesystem is getting full.

Avati <avati@dev.gluster.com> BUG: 584 (automatically configure 'lookup-unhashed' option) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=584
