[Gluster-users] [Gluster-devel] RPMs for Samba 4.1.3 w/ Gluster VFS plug-in for RHEL, CentOS, etc., now available

Fri Feb 14 06:52:05 UTC 2014

HI again,

I had the same issue. I got it working by:
Adding -- kernel share modes = No to the sahres
EX.:
[home]
comment=gluster test
vfs objects=glusterfs
glusterfs:volume= sambacluster
glusterfs:volfile_server = 172.17.1.1
path=/ads/home
read only=no
posix locking =NO
kernel share modes = No

By the way running Centos6.4 Samba 4.1.4, gluster 3.4.1qa2.

Good Luck
Daniel

Hi,

This is failing for me.  I've had the same problems after trying to build my
own vfs_glusterfs from source.  I'm certain I'm doing something stupid. 

Client is a Windows Server 2008R2 64bit machine with AD authentication.

Server is CentOS 6.4, Gluster 3.4.1GA, Samba 4.1.4 with matching
samba_vfs_glusterfs as per this thread, AD authentication (sssd for the
Linux/PAM/nsswitch side, and Samba is configured as a member server).  The
Gluster volume is working fine (this is our production test/backup cluster,
and has been in operation for over a year).

Samba works fine when pointing to a local FUSE mount (this is how we run in
production today for Windows and Mac clients).  When I change to
vfs_glusterfs, it all goes wrong.

Client errors include:

Action: On Windows regular windows explorer directory browsing
Result: All good.  Much faster than regular Samba to FUSE.

Action: On Windows: Right click -> New ->  Text Document
Result: "Unable to create the file "New Text Document.txt".  The system
cannot find the file specified.

Action: 
On a Linux box: dmesg > test.txt
On Windows: double-click test.txt
Result: The process cannot access the file because it is in use by another
process

Action: On Windows: drag and drop a text file to a share
Result: nothing (file not copied, no error dialog).

The log seems similar to bug
https://bugzilla.redhat.com/show_bug.cgi?id=1062674

Please put "kernel share modes = No" for the shares and let us know if it
works for you.

-Lala

/etc/samba/smb.conf:

[global]
        workgroup = BLAH
        server string = Samba Server Version %v
        log file = /var/log/samba/log.%m
        max log size = 50
        security = ads
        passdb backend = tdbsam
        realm = BLAH
        domain master = no
        domain logons = no
        wins support = yes
        wins proxy = yes
        dns proxy = yes
        load printers = no
## Shares
[prodbackup]
        vfs object = glusterfs
        glusterfs:volume = prodbackup
        glusterfs:volfile_server = localhost
        path = /
        Comment = prodbackup
        browseable = yes
        writable = yes
        guest ok = no
        valid users = +prod
        create mask = 0660
        force create mode = 0660
        directory mask = 0770
        force directory mode = 0770
        hide dot files = no

Any pointers would be appreciated.
