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
