Config

Identify shares to share:

root@exi:~# ls -la /mnt/btr/foo/
total 2
drwxr-xr-x 2 root root   3 Jan 13 09:19 .
drwxr-xr-x 3 root root   3 Jan 13 09:11 ..
-rw-r--r-- 1 root root 511 Jan 13 09:19 history
root@exi:~# ls -la /mnt/tank/bar/
total 2
drwxr-xr-x 2 root root   3 Jan 13 09:20 .
drwxr-xr-x 3 root root   4 Jan 13 09:14 ..
-rw-r--r-- 1 root root 286 Jan 13 09:20 history

In /etc/samba/smb.conf modify:

interfaces = lo enp4s0
bind interfaces only = yes

[btr]
comment = btr samba share
path = /mnt/btr
read only = no
writable = yes
browseable = yes
guest ok = yes
valid users = @alex

[tank]
comment = tank samba share
path = /mnt/tank
read only = no
writable = yes
browseable = yes
guest ok = yes
valid users = @alex

Add samba user:

# sudo smbpasswd -a alex
New SMB password:
Retype new SMB password:
Added user alex.

Change file owner/permissions

To grant read/write/execute permissions to the sharing directory, run setfacl:

setfacl -R -m "u:alex:rwx" /mnt/btr/foo

# setfacl -R -m "u:alex:rwx" /mnt/btr/foo
setfacl: /mnt/btr/foo: Operation not supported
setfacl: /mnt/btr/foo/history: Operation not supported

Instead:

chown -R alex:users /mnt/btr/foo/
chown -R alex:users /mnt/tank/bar/
