Task Status of Volume testvol
------------------------------------------------------------------------------
There are no active volume tasks
Steps to Reproduce:
===================
1. Create a 1x(4+2) disperse volume
2. start creating files/dirs from the client.
3. On one of the storage node, turn on/off the USS feature with 'gluster volume
set testvol uss on/off'
Actual results:
=================
IO error on the client
Expected results:
=================
There should not be any IO error
Additional info:
================
volume statedumps will be attached to this bug.
