[Samba] Unable to create subdirectories/files in samba mount when using vfs objects = glusterfs

Hi Team,

 

I am trying to setup a samba CTDB cluster to export gluster volme as samba
share. While CTDB cluster works well, I ran into an issue with creating
subdirectories and also creating files/directories within subdictories when
accessing the share from both linux  and windows servers.

 

Setup details :

 

We have a three node cluster with nodes snode1, snode2 and snode3. I have a
gluster volume named smbshare32 exported as samba share using vfs objects =
glusterfs (libgfapi).  When I mount the share on linux, I am able to create
files/directories in the root of the mount point i.e under /smbshare32.

 

[root at sclient1 /]# df -h /smbshare32

Filesystem                      Size  Used Avail Use% Mounted on

//10.4.0.31/gluster-smbshare32  600G  6.1G  594G   2% /smbshare32

[root at sclient1 /]# 

 

[root at sclient1 /]# cd /smbshare32

[root at sclient1 smbshare32]# ls

[root at sclient1 smbshare32]# mkdir subdir1

[root at sclient1 smbshare32]# touch a

[root at sclient1 smbshare32]# ls

a  subdir1

[root at sclient1 smbshare32]# 

 

When I switch to subdir1, I cannot create files or directories. Same issue
happens on windows , but I get a different error message it says ?the file ? ?
is too large for the destination file system.

 

[root at sclient1 smbshare32]# cd subdir1/

[root at sclient1 subdir1]# touch a

touch: setting times of ?a?: Invalid argument

[root at sclient1 subdir1]# mkdir subdir2

mkdir: cannot create directory ?subdir2?: Invalid argument

[root at sclient1 subdir1]# 

 

Below two scenarios works well:

 

If I mount the cifs mount on the client using vers 1.0 , I am able to create
files and directories.

 

//10.4.0.31/gluster-smbshare32 /smbshare32 cifs  
vers=1.0,credentials=/etc/smbclient.passwd     0       0

 

[root at sclient1 /]# cd /smbshare32

[root at sclient1 smbshare32]# ls

a  subdir1

[root at sclient1 smbshare32]# cd subdir1/

[root at sclient1 subdir1]# touch a

[root at sclient1 subdir1]# mkdir test2

[root at sclient1 subdir1]# 

 

Also if I mount the gluster volume using fuse and then export the fuse mount as
samba share, I have no issues creating file/directories.   We would prefer
accessing the gluster volume using vfs_glusterfs and also use the latest SMB
protocol version.

 

Could you please let me know if I missed some configuration.

 

I have mounted the gluster volume using fuse and set below ACLs as for the
volume.

If someone knows the answer to your problem (sorry, but I do not), they 
will answer in due course. Please be patient until this happens.

Looks like I missed this thread and replied privately. Anyways, refer
GlusterFS GitHub issue #1392[1] for details.
