Steps to Reproduce:
1. Created 6*2 distriubuted-replicate volume
2. Mounted on client (both fuse and nfs mount)
3. Created fuse-test and nfs-test directories on fuse and nfs mount respectively.
4. Ran script1.sh on both fuse and nfs test directories. Script does the directory and file creation, dd etc.
5. Tried to remove all the files and directories from fuse and nfs mount simultaneously.
6. Tried to do ls from fuse and nfs mount. NFS mount hung and one of the server reported a core.
