Comment 1 Krishna Srinivas 2010-04-16 23:38:33 UTC 
distribute option lookup-unhashed should be on by default. 
Assume the following scenario:

* distribute subvolumes expanded
* defrag script is run to create new hash ranges, still no link files are created
* create of an existing file name is done. This causes the create to succeed as it looks up at a subvol pointed to by new hash range. hence duplicate entries are created.

Making lookup-unhashed auto not fix the above problem. lookup-unhashed on will fix.
