[root@ip-10-138-150-225 ~]# setfattr -x trusted.glusterfs.volume-id /data/share
[root@ip-10-138-150-225 ~]# setfattr -x trusted.gfid /data/share
[root@ip-10-138-150-225 ~]# service glusterd stop
       [  OK  ]

[root@ip-10-138-150-225 ~]# cd /data/share/

.  ..  a1  a2  a3  b1  b2  b3  c1  c2  c3  c4  d1  d2  d3  .glusterfs
[root@ip-10-138-150-225 share]# rm -rf .glusterfs
[root@ip-10-138-150-225 share]# ls
a1  a2  a3  b1  b2  b3  c1  c2  c3  c4  d1  d2  d3
[root@ip-10-138-150-225 share]# cd /var/lib/glusterd/
[root@ip-10-138-150-225 glusterd]# ls 
glusterd.info  glustershd  groups  hooks  nfs  options  peers  vols
[root@ip-10-138-150-225 glusterd]# rm -rf *
[root@ip-10-138-150-225 glusterd]# service glusterd start
Starting glusterd:                                         [  OK  ]

/data/share : Is the directory for which gluster is setup..
.glusterfs : Is the directory where all meta data is stored so it need to be removed..
/var/lib/glusterd/ : Directory where volume information is stored..

Note don't delete the all files in /var/lib/glusterd/ if you have more than one gluster volume configured in server..
