I checked now if shapshot exists.
Both servers has no snapshots.
As I have no snapshot, when disk full problem will be happened, I will
have to reboot glusterfsd.
(web1)
[root at web1 ~]# gluster snap list
No snapshots present
[root at web1 ~]# gluster snap info
No snapshots present
[root at web1 ~]# gluster snap status
No snapshots present
[root at web1 ~]# gluster snap delete all
No snapshots present
(web2)
[root at web2 ~]# gluster snap list
No snapshots present
[root at web2 ~]# gluster snap info
No snapshots present
[root at web2 ~]# gluster snap status

[root at web2 ~]# gluster snap delete all
