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@pgsql-1 media-cifs]# gluster v info disperse_vol_2

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

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

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