Description of problem:

Here is my volume configuration:

  # gluster volume info testvol
 
  Volume Name: testvol
  Type: Distribute
  Status: Started
  Number of Bricks: 1
  Transport-type: tcp
  Bricks:
  Brick1: server1:/bricks/0001
  Options Reconfigured:
  performance.io-thread-count: 1
  performance.flush-behind: off
  performance.quick-read: off

Now, when I am doing file operations, I can see two glusterfsd threads are writing to the brick. First I found out this using `top -p $(pgrep glusterfsd) -H`, there it was clear that two thread were consuming CPU. Then I performed strace on those threads. I could see both of these threads were doing IO.
