I managed to create a samba share for profiles with something like this

[global]
    ...
    vfs objects = acl_xattr btrfs snapper
    ...

[Profiles]
    path = /srv/samba/profiles
    read only = no

and the snapper config

SUBVOLUME="/srv/samba"
FSTYPE="btrfs"
ALLOW_USERS=""
ALLOW_GROUPS="domänen-benutzer" # (yes, it's a german AD, not my fault.. :/ )
SYNC_ACL="yes"
...

Also the .snapshot folder has

# ls -lha
...
drwxr-xr-x+ 1 root domänen-benutzer  570 26. Sep 12:00 .snapshots

Now I can (as a arbitrary user) exec snapper -c samba list and it works and will list all snapshots, also I can execute snapper -c samba diff ..... and it will list me the difference between two snapshots (only for that user of course and if I log in as an domain-admin it will list all diffs).

The only problem now is, that I cannot see snapshots in the windows explorer, as it should be :/ Does anyone has a solution for this? I mean, I follwed the guide in the man 8 vfs_snapper and it works but not for the explorer itself.

Ps. I would like to have a new tag snapper, but I don't have the required 300 rep to do so, if anyone could add this please and remove this ps :) thanks

  • I don't know if it is applicable to Linux/btrfs, but on Solaris/ZFS, you specify the mapping of groups regardless of domain language (as internally, Windows Server as well as Samba4 map Domain Users, Domain Administrators, Power Users and the other reserved names to the displayed language).

  • I assume you followed documentation similar to suse.com/documentation/sles-12/book_sle_admin/data/… ? Are there any ACL entries that might deny access (they work on top of your basic permissions)?

  • You might be running into a subtree limitation within Samba. Can you view any nested BTRFS subvolumes on the Windows hosts? Snapshots being a new subvolume, and all.

I managed to solve this issue (thanks to the comments :D ) The problem was, that the samba share and the snapshot were not in the same directory (/srv/samba vs /srv/samba/profiles). They have to be in the exact same spot, that's the mystery.
