Fixed In Version: glusterfs-3.8.4-54.15
Doc Type: Bug Fix
Doc Text:
Previously, glusterd could not handle blank real paths when checking if brick path is already a part of another volume, during volume create. Hence, volume create requests would fail with the error 'Brick may be containing or be contained by an existing brick'. This update fixes the path comparison logic to correctly handle blank paths, and thus prevents failure of further volume create requests.

Comment 8 Bala Konda Reddy M 2018-07-13 10:21:54 EDT 
Build: 3.8.4-54.15

On a live-build(3.8.4-54.10) I hit the issue by following the below steps.

1. Ran glusterd with gdb prior to that install glusterfs-debuginfo packages
   gdb -p `pidof glusterd`
2. Do "b glusterd_is_brickpath_available" and continue using c
3. Go till line 1326 (where brickinfo->real_path will get the brick path for creating the volume)
4. perform  p brickinfo->real_path = "" and continued the steps  
5. The volume will fail.

Now with the fix, followed the above steps
The new volume created successfully.

Hence marking this as verified
