[Gluster-users] Gluster USER SERVICEABLE SNAPSHOTS: Cannot see `.snaps` directory

[samfisher1]

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.

```

[root at pgsql-1 media-cifs]# gluster v info disperse_vol_2




Volume Name: disperse_vol_2

Type: Disperse

Volume ID: a8bd1d15-20c0-43af-a66e-eb166bd92f4c

Here is the snapshot info:

```

[root at pgsql-1 media-cifs]# gluster snap info snap_disperse_vol_2_test1

Snapshot                  : snap_disperse_vol_2_test1

        Origin Volume name        : disperse_vol_2

        Snaps taken for disperse_vol_2      : 5

        Snaps available for disperse_vol_2  : 251

        Status                    : Started

```

But I can not see any .snaps directory in the media3 directory.

```

[root at pgsql-1 media-cifs]# mount -t nfs 10.10.10.1:/disperse_vol_2 /media3/

[root at pgsql-1 media-cifs]# ls -a /media3

.       21.txt  24.txt  27.txt  2.txt   32.txt  35.txt  

..      22.txt  25.txt  28.txt  30.txt  33.txt  36.txt   

```

I can access snapshot by using FUSE mount and it works fine.

```

[root at pgsql-1 media-cifs]# mount -t glusterfs 10.10.10.1:/snaps/snap_disperse_vol_2_test1/disperse_vol_2 /mnt/snap/

[root at pgsql-1 media-cifs]# ls /mnt/snap/

20.txt  23.txt  26.txt  29.txt  31.txt  34.txt  37.txt  3.txt   42.txt  45.txt  48.txt  50.txt  7.txt

21.txt  24.txt  27.txt  2.txt   32.txt  35.txt  38.txt  40.txt  43.txt  46.txt  49.txt  5.txt   8.txt

22.txt  25.txt  28.txt  30.txt  33.txt  36.txt  39.txt  41.txt  44.txt  47.txt  4.txt   6.txt   9.txt

```

I haven't any clues to solve this problems, pls help me. tks~
