Hi Anoop

this might bring us closer!

I can see all? snapshots which are available on the gluster cluster. I 
can enter those directories and see and read all files I expect.

Yes, there is a file called; /var/log/glusterfs/srv-glvol_samba.log

When the error in samba occurs there are these entries:
[2023-05-24 12:30:09.764077 +0000] I [MSGID: 139001] 
[posix-acl.c:252:posix_acl_log_permit_denied] 0-posix-acl-autoload: 
client: -, gfid: 08ee40ea-8f84-4240-a6b1-e56e0d393016, 
req(uid:1001103,gid:1000513,perm:4,ngrps:20), 
ctx(uid:0,gid:0,in-groups:0,perm:000,updated-fop:INVALID, acl:-) [Keine 
Berechtigung]
[2023-05-24 12:30:09.764234 +0000] W [fuse-bridge.c:1642:fuse_fd_cbk] 
0-glusterfs-fuse: 201346: OPENDIR() /admin/projects/.snaps => -1 (Keine 
Berechtigung)

This looks like we are getting closer!

And you are right, you asked what has changed. And in the back of my 
head it rings a bell. I might have added vfs_glusterfs_fuse later on. So 
probably I used the mount point directly when it was working. But 
removing the vfs module does not heal the situation.

I am really thankful for all your effort you are putting in this!

Sebastian

Does it make a difference if you re-mount the volume without 'acl'
option? Even otherwise can you try listing the snapshot contents from
the server as a user(and not super user) who in reality tries to list
previous versions from Windows? I feel like it has something to do with
permissions setup for the user accessing the share.
