How reproducible:
always

Steps to Reproduce:
1.setup nfs windows client
2.make some dirs and files
3.try to remove them
  
Actual results:
deletion fails

Expected results:
the deletion should succeed

Hi,

We couldn't delete any files and directories when connecting glusterfs to windows via NFS.
We could make/change files and directories.
Although it has written that glusterfs can be connected with windows NFS client in the page shown below.
Any ideas to workaround/fix this ?

http://docs.redhat.com/docs/en-US/Red_Hat_Storage_Software_Appliance/3.2/html/User_Guide/chap-Administration_Guide-GlusterFS_Client.html

ENVIRONMENT:
OS: RHEL6 x86_64
GlusterFS: 3.2.5
Windows OS: Windows2008R2
Windows NFS ver: NFSv3

We tried to solve this problem with Microsoft.
We captured network traffic between NFS server and NFS client.
Access call is sent to NFS server from NFS client before sending delete call.
We found that glusterfs has returnd 'not allow (ACCESS3_DELETE=0)' to the access call.
In the case that glusterfs is connected to linux via NFS, linux NFS client is deleting files and directories by ignoring 'not allow (ACCESS3_DELETE=0)'.
However, windows NFS client does not ignore 'not allow (ACCESS3_DELETE=0)' and does not try to files and directories.

Our research summary:
NFS server NFS client responce to access call
gluster NFS server　<->　windows NFS client Not Allow Delete (can't delete any files and directories)
gluster NFS server <->　linux NFS client Not Allow Delete (can delete files and directories by ignoring responce to access call)
linux NFS server <->　windows NFS client Allow Delete (can delete files and directories)

We took captures of network traffic on three cases.
Summary of the captures to access call are below for reference.
