> 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:

Are all the files on the removed bricks zero sized 'T' files? If yes, these are
internal files and can be ignored.
