[Samba] samba4 with glusterfs

[Ulrich Schinz]

Hi Sambalist,

maybe someone with some glusterfs experience can help me.

I have a running samba4 installation here.
Now i tried to get glusterfs configured so I can use glusterfs as an 
additional storagesystem.

The setup of glusterfs worked pretty easy. I tried multiple 
configurations with up to 4 virtual machines (Virtual Box).
The bricks are xfs-filesystems.

Mounting glusterfs (mount -t glusterfs gluster01:/volume1 
/samba/glusterfs -o acl) is working as well, but I have a strange error.
Trying to set the rights on that share /samba/glusterfs from windows is 
not possible.

Gluster tells me following:
[2013-05-10 15:43:43.508988] E [posix.c:2583:posix_getxattr] 
0-dfsvol01-posix: getxattr failed on /export/brick1/: user.DOSATTRIB (No 
data available)

another error:
[2013-05-10 15:49:54.998621] E [posix.c:2583:posix_getxattr] 
0-dfsvol01-posix: getxattr failed on /export/brick1/:

[2013-05-10 15:49:55.028952] I

REMOVEXATTR / (00000000-0000-0000-0000-000000000001) ==> -1 (No data 
available)


And it's right, there is no data in there... samba wants to write it...

I did a (in my opinion identical) setup on 2 virtualbox machines before. 
There everything is working fine.

Trying to set xattrs in shell works fine, it works on the bricks (xfs) 
and on the mounted glusterfs-volume (mount -t glusterfs ... -o acl ... 
or without -o acl, doesnt matter). It
works perfect, no errors in logfile nothing. just setfattr -n user.test 
-v test file.txt and thing is done... Prequesites for samba should be 
given in that case....

System: Debian Wheezy
Brick fs: xfs (mounted with defaults)
gluster version: 3.3.1
gluster replica 2 (2 nodes)

Has someone any idea whats missing?

Kind regards
