Fixed In Version: glusterfs-3.12.2-14
Doc Type: Bug Fix
Doc Text:
Earlier, during volume create, glusterd failed to handle blank real paths while checking if the brick path is already a part of another volume. Hence, volume create requests would fail. This update fixes the path comparison logic. Now, glusterd can handle blank paths and prevents failure of volume create requests.

Comment 13 Bala Konda Reddy M 2018-07-19 05:31:14 EDT 
Build: 3.12.2-14

Simulated the bug using gdb as below
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.

The new volume created successfully.

Hence marking this as verified
