+++ This bug was initially created as a clone of Bug #1202218 +++
Description of problem:
=======================
In a 1x(8+4) disperse volume, there are input/output errors on nfs mount after
2 bricks were brought down and the gluster volume is started by force. The
mount point goes into state state and takes long time to recover.
Version-Release number of selected component (if applicable):
==============================================================
[root at vertigo ~]# gluster --version

How reproducible:
=================
100%
Steps to Reproduce:
1. create a 1x(8+4) disperse volume.
2. NFS mount on the client and start creating files/directories with mkdir and
dd
3. Now, bring down 2 of the bricks
4. Wait for some time and let IO run.
5. Start the gluster volume with force option from any of the server.
Actual results:
================
input/output errors on nfs mount
Expected results:
=================
No errors should be seen and IO should resume as normal
Gluster volume options:
=======================
