Nothing specific except the data creation was in progress. Before this test,
performed the ignore_deletes test as mentioned in bug id 1224906. 



Version-Release number of selected component (if applicable):
=============================================================



Steps Carried:
1. Create master and slave cluster
2. Create and start master,meta,slave volume
3. Mount the volume fuse,nfs on client
4. Create huge set of dat (copy /etc multiple times overs fuse and nfs client)
5. Performed basic test of ignore_deletes option and hit bug id 1224906
6. Set the ignore_deletes to false.
7. Started creating huge set of data from master (copy /etc multiple times over
