Thanks

Hi Alessandro,

My system:

CentOS 7

samba-vfs-glusterfs-4.1.1-37.el7_0.x86_64
This is the rpm that ships glusterfs.so which Samba searched for and did not find.

samba-winbind-4.1.1-37.el7_0.x86_64
samba-libs-4.1.1-37.el7_0.x86_64

glusterfs 3.6.2 built on Jan 22 2015 12:59:57

Try this, work fine for me:

[GFSVOL]
    browseable = No
    comment = Gluster share of volume gfsvol
    path = /
    read only = No
    guest ok = Yes
    kernel share modes = No
    posix locking = No
    vfs objects = glusterfs
    glusterfs:loglevel = 7
    glusterfs:logfile = /var/log/samba/glusterfs-gfstest.log
    glusterfs:volume = vgtest
    glusterfs:volfile_server = 192.168.2.21

Hi,
I’ve created and started a new replica volume “downloadstat” with CIFS export enabled on GlusterFS 3.6.2.
I can see the following piece has been added automatically to smb.conf:
[gluster-downloadstat]
comment = For samba share of volume downloadstat
vfs objects = glusterfs
glusterfs:volume = downloadstat
glusterfs:logfile = /var/log/samba/glusterfs-downloadstat.%M.log
glusterfs:loglevel = 7
path = /
read only = no
guest ok = yes

I restarted smb service, without errors.
When I try to access from Win7 client to “\\gluster01-mi\gluster-downloadstat<file:///\\gluster01-mi\gluster-downloadstat>” it asks me a login (which user do I need to put?) and then gives me error “The network path was not found”
The user you use to login depends on your Samba setup, if it is in AD environment , you would use one of the AD users. If it is not, then you will have to use a user added to Samba on the server
using smbpasswd -a <user>. Also, make sure that the same user exists on the node(s) and has rights on the bricks.


and on Gluster smb.log I see:
[2015/02/09 17:21:13.111639,  0] smbd/vfs.c:173(vfs_init_custom)

  vfs_init failed for service gluster-downloadstat

Can you explain how to fix?
Thanks

Subject: [Gluster-users] cannot delete non-empty directory

I am seeing these messsages after I delete large amounts of data using gluster 3.6.2.
cannot delete non-empty directory: old_shelf4/Aegis/!!!Programs/RavenCFD/Storage/Jimmy_Old/src_vj1.5_final

From the FUSE mount (as root), the directory shows up as empty:

# pwd
/backup/homegfs/backup.0/old_shelf4/Aegis/!!!Programs/RavenCFD/Storage/Jimmy_Old/src_vj1.5_final

# ls -al
total 5
d--------- 2 root root    4106 Feb  6 13:55 .
drwxrws--- 3  601 dmiller   72 Feb  6 13:55 ..

However, when you look at the bricks, the files are still there (none on brick01bkp, all files are on brick02bkp).  All of the files are 0-length and have ------T permissions.
Any suggestions on how to fix this and how to prevent it from happening?

This is using gluster 3.6.2 on a distributed gluster volume that resides on a single machine.  Both of the bricks are on one machine consisting of 2x RAID-6 arrays.
