            Bug ID: 1370113
           Summary: SMB:Create time getting updated always when the file
                    is accessed or modified on windows client
           Product: GlusterFS
           Version: 3.8.3
         Component: gluster-smb
          Severity: high
          Assignee: bugs at gluster.org

Description of problem:
*****************************

On a windows client when a MS-word doc is created, in the properties it updates
create time, modified time and access time.
Now when the doc is accessed again and modified and again the properties are
checked , it actually updates the create time as well along with mtime and
atime.

Similar test execution result on different shares as follows:

1) On windows local share : create time doesn't changes when the doc is
accessed or modified.
2) On Samba-xfs share  : Create time doesn't doesn't changes when the doc is
accessed or modified.

Only with glusterfs-samba share the issue is seen.

Also tested with stat-prefetch off and on, doesn't make any difference.


Version-Release number of selected component (if applicable):
*********************************************
glusterfs-3.8.2-0.24.gitf524648.el7.x86_64

Note: This is a private build based on 3.8.3 with few md-cache patches.


How reproducible:
Always

Steps to Reproduce:
***************************
1.Create a 2X2 volume and access it from windows client
2.Create a ms-word doc on the share
3.Check the properties of doc , check atime,mtime and create time
4.Open the doc and write some data in it.
5. Again verify the properties for mtime, atime and create time

Actual results:
****************************
The create time also gets updated same as access time and modify time.


Expected results:
****************************

The create time of doc should not be changed along with modify and access time

Additional info:

Doesn't look like issue with md-cache. Will verify on the build without
md-cache patches and will update the bug.
