2.mount the volume and start kernel untar on the mount point
3.keep on adding bricks to the volume i.e. volume becomes distributed-stripe with increasing distribute count
  
Actual results:

Comment 1 shishir gowda 2012-05-07 08:54:23 UTC 
The issue is seen when a non-distribute volume is converted to a distribute
volume(through add-brick). Existing directories would not have any extended
attributes set on them, which would lead to failure.

Removing the 3.3.0beta milestone, as this issue can not be fixed in this time
frame.
