            Bug ID: 1596904
           Summary: remove-brick is failing to remove hidden dot files
           Product: GlusterFS
           Version: mainline
         Component: object-storage
          Severity: low
          Assignee: bugs at gluster.org
          Reporter: chris.king at conoak.com
                CC: bugs at gluster.org



Description of problem:

after completing "remove-brick", the removed drive is still full of the hidden
"dot files" (eg .htaccess). However, the dot files where still relocated to new
bricks on the volume (not lost).


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

glusterfs 4.0.2


How reproducible:

I have only run this once, but both bricks still contained the all of the
hidden dot files.


Steps to Reproduce:
1. ensure that you have hidden files on volume
2. gluster volume remove-brick conoak-photos
liberator:/mnt/disk1/conoak-photos-data liberator:/mnt/disk3/conoak-photos-data
start
3. gluster volume remove-brick conoak-photos
liberator:/mnt/disk1/conoak-photos-data liberator:/mnt/disk3/conoak-photos-data
status
4. wait until status is "completed"
5. gluster volume remove-brick conoak-photos
liberator:/mnt/disk1/conoak-photos-data liberator:/mnt/disk3/conoak-photos-data
commit
6. find /mnt/disk1 -type f | grep -v "/[.]glusterfs/"
7. find /mnt/disk3 -type f | grep -v "/[.]glusterfs/"


Actual results:

hundreds of files still be found on the removed brick
eg
/mnt/disk1/conoak-photos-data/Photos/2003/2003-05-02/downsize/.picasa.ini
/mnt/disk1/conoak-photos-data/Photos/2003/2003-05-02/.picasa.ini
/mnt/disk1/conoak-photos-data/Photos/2003/2003-05-25/.picasa.ini
/mnt/disk1/conoak-photos-data/Photos/2003/2003-05-30/.picasa.ini


Expected results:

Expected no files on the removed brick.


Additional info:

one of the bricks has zero sized files and had the "T" attribute, the other
brick and volume where original size;

ls -la /mnt/disk1/conoak-photos-data/Photos/2003/2003-05-02/.picasa.ini
