It works. Thanks, Aravinda.
According to Red Hat's documentation, I can see the hidden folders by using ls
-l command. It seems that this is different from the content in the Red Hat
document.
[root@pgsql-1 ~]# ls -la /mnt/glusterfs_disperse_vol_2/
... cannot see any hidden directory ...
[root@pgsql-1 ~]# ls -la /mnt/glusterfs_disperse_vol_2/.snaps_disperse_vol_2

Observed one more thing from your Volume info. Snaps directory is configured as
----
features.snapshot-directory: .snaps_disperse_vol_2

Try `ls /media3/.snaps_disperse_vol_2` and `ls
/mnt/disperse_vol_2/.snaps_disperse_vol_2`

It makes me crazy, I don't have any clues to solve this problem.

I think `.snaps` is not shown when you do `ls` it is a virtual directory.
Please confirm if it is not visible when you run ls command as below.
ls /media3/.snaps
In the fuse example, Snap volume itself is mounted and not using User
Serviceable snapshots feature. Try mounting as below and see if .snaps
directory is visible.
mount -t glusterfs 10.10.10.1:/disperse_vol_2 /mnt/disperse_vol_2
ls /mnt/disperse_vol_2/.snaps

Tks, Aravinda
The snapshot is already activated and you can see the snapshot status is
started in the previous command output.

Sorry for disturbing you... Uh, I met a very strange GlusterFS problem: I can
access snapshots by using FUSE mount and it works fine. However, when I test
Gluster USER-SERVICEABLE snapshots feature, I find I cannot see .snap directory
in the NFS shared directory. So pls help me solve this problem, many thanks~
My Gluster version is glusterfs 8.6. My OS version is CentOS 7.9.2009
Here is gluster volume and snapshot info.

But I can not see any .snaps directory in the media3 directory.
```
[root@pgsql-1 media-cifs]# mount -t nfs 10.10.10.1:/disperse_vol_2 /media3/

I can access snapshot by using FUSE mount and it works fine.
```
[root@pgsql-1 media-cifs]# mount -t glusterfs
