how to change folder creation permissions in samba

omv 5.5.11

I have a NAS shared through samba which I use to store data from docker containers, the problem I have is that I need to be able to create directories with 777 permissions and by default samba creates them with 755

Original conf omv

/etc/samba/smb.conf

#======================= Share Definitions =======================
[storage]
comment = storage smb
path = /srv/dev-disk-by-label-storage/
guest ok = yes
guest only = no
read only = no
browseable = yes
inherit acls = yes
inherit permissions = yes
ea support = yes
store dos attributes = no
vfs objects =
printable = no
create mask = 0664
force create mode = 0664
directory mask = 0775
force directory mode = 0775
hide special files = yes
follow symlinks = yes
hide dot files = no
read list =
write list =

I tried modifying the smb.conf configuration file and restarting the server, but it returns the default values.

What should I do to change these settings in samba ???

I followed the steps of your guide but it didn't work for me

add these lines

/etc/default/openmediavault

OMV_SAMBA_CREATEMASK="0777"
OMV_SAMBA_DIRECTORYMASK="2777"
OMV_SAMBA_SHARE_CREATEMASK="0777"
OMV_SAMBA_SHARE_DIRECTORYMASK="2777"
OMV_SAMBA_SHARE_FORCECREATEMODE="0777"
OMV_SAMBA_SHARE_FORCEDIRECTORYMODE="2777"

restart the services

sudo omv-salt stage run prepare

sudo omv-salt deploy run samba

check smb settings

/etc/samba/smb.conf

I tried creating a file/dir, also change the permissions but takes the default permissions 755

/etc/fstab in docker host

the drive is mounted with the omv root credentials

//192.168.0.241/storage /srv/nas cifs user=root,pass=1234567890,iocharset=utf8,noperm 0 0

any idea why this happens?

I tried to create it on the machine that has the samba unit mounted (DOCKER SERVER ubuntu 20.04)

OMV -------- DOCKER SERVER

I created it with linux command, inside the mounted smb unit

touch file
mkdir dir

In the SERVER DOCKER the unit is mounted using the CIFS protocol so it should work.

//192.168.0.241/storage /srv/nas cifs user=root,pass=1234567890,iocharset=utf8,noperm 0 0

On the other hand I see that the directories and files are created with the 777 permissions in OMV

When I check on the SERVER DOCKER this is not the case.

I think SMB does not work for what I want
