            Bug ID: 1554286
           Summary: Xattr not updated if increase the retetion of a
                    WORM/Retained file
           Product: GlusterFS
           Version: 3.12
         Component: unclassified
          Assignee: bugs at gluster.org
          Reporter: david.spisla at iternity.com
                CC: bugs at gluster.org



Description of problem:
At the moment, gluster stores the default retention period in the
retention_state data model.This model contains several informations about the
WORM state and defines it. The informations inside that model are used in
several places in the WORM Xlator. After setting all datas, this model will be
serialized and saved as xattr named "trusted.reten_state".

If someone increases the atime of a WORM/Retained file, there will be a new
atime and therefore a new retention. But the value of the retention_period
which was initially stored in the xattr named "trusted.reten_state", will not
be updated.

Version-Release number of selected component (if applicable):
3.12.5


How reproducible:
You need access to a gluster volume via FUSE or something else and
worm-file-level must be switched on.

Steps to Reproduce:
[root at fs-debug1 gv0]# date && echo test >> test.txt
Mon Mar 12 10:17:51 GMT 2018

[root at fs-debug1 gv0]# date && chmod 444 test.txt 
Mon Mar 12 10:18:06 GMT 2018

[root at fs-debug1 gv0]# date && getfattr -d -m "trusted.reten_state"
/gluster/brick1/glusterbrick/test.txt 
Mon Mar 12 10:18:32 GMT 2018
getfattr: Removing leading '/' from absolute path names
# file: gluster/brick1/glusterbrick/test.txt
trusted.reten_state="11/120/180"

[root at fs-debug1 gv0]# date && touch -a -t 201803121125 test.txt Mon Mar 12
10:18:46 GMT 2018

[root at fs-debug1 gv0]# stat test.txt

getfattr: Removing leading '/' from absolute path names
# file: gluster/brick1/glusterbrick/test.txt
trusted.reten_state="11/120/180"


Actual results:
The value of the retention_period (120) is not updated in the xattr after
increasing the atime of a WORM/Retained file manually.


Expected results:
This value should be updated in the xattr
