[Samba] archlinux samba4 provision error

[shadrock uhuru]

Hi everyone

archlinux Release: 2014.06.01

using the information on
https://wiki.archlinux.org/index.php/Samba_4_Active_Directory_Domain_Controller

to install my Active Directory Domain Controller, i provision with :-
samba-tool domain provision --use-rfc2307 --interactive --use-xattrs=yes
Realm [LOCALDOMAIN]: SAT.CO.UK
Domain [SAT]:
Server Role (dc, member, standalone) [dc]:
DNS backend (SAMBA_INTERNAL, BIND9_FLATFILE, BIND9_DLZ, NONE)
[SAMBA_INTERNAL]:
DNS forwarder IP address (write 'none' to disable forwarding) [10.4.1.2]:
Administrator password:
Retype password:

which gives me the following error output :-

ERROR(<class 'samba.provision.ProvisioningError'>): Provision failed -
ProvisioningError:
Your filesystem or build does not support posix ACLs, which s3fs requires.
Try the mounting the filesystem with the 'acl' option.
  File "/usr/lib/python2.7/site-packages/samba/netcmd/domain.py", line
398, in run
    use_rfc2307=use_rfc2307, skip_sysvolacl=False)
  File "/usr/lib/python2.7/site-packages/samba/provision/__init__.py",
line 2052, in provision
    raise ProvisioningError("Your filesystem or build does not support
posix ACLs, which s3fs requires.  Try the mounting the filesystem with
the 'acl' option.").

this my fstab file.

cat /etc/fstab
# /dev/sda1
UUID=6d501e92-b7be-4885-b6ce-4facd647623e    /             ext4         
rw,relatime,data=ordered,user_xattr,acl,barrier=1    0 1

# /dev/sda2
UUID=fa951f67-d09c-412e-8d8a-07020863e3f0    /home         ext4         
rw,relatime,data=ordered,user_xattr,acl,barrier=1    0 2

and this is the test i did to confirm my acl was working.

tune2fs -l /dev/sda1 | grep "Default mount options:"
Default mount options:    user_xattr acl
tune2fs -l /dev/sda2 | grep "Default mount options:"
Default mount options:    user_xattr acl

setfacl and getfacl work as expected.

can anyone provide me with an solution to my problem.
thanks
