[Gluster-users] dispersed volume + cifs export does not work (replicated + cifs works fine)

[Felix Kölzow]

Dear Gluster-Users,

_
_

_short story:_

_
_

Two volumes are exported via smb/cifs with the

(almost) the same configuration with respect to smb.conf. The replicated
volume

is easily accessible via cifs and fuse. The dispersed volume is
accessible via fuse,

but not via cifs.

Error message from windows client:

The parameter is incorrect



Maybe the error is somehow related to this:

_more information:
_


We have created a gluster setup that consists of three servers, and each
server

provides two bricks. Two volumes are created on these bricks and are
going to exported via

smb/cifs.


  * replicated distributed
  * dispersed


The volume settings are given here:

The export via cifs looks:

_distributed replicated:_

[gluster-replicated_cifs]
vfs objects = fruit acl_xattr glusterfs
acl_xattr:ignore system acls = yes
acl_xattr:default acl style = windows
glusterfs:volume = replicated_cifs
glusterfs:logfile = /var/log/samba/glusterfs-replicated_cifs.%M.log
glusterfs:loglevel = 7
kernel share modes = no
path = /
read only = no
guest ok = no
browseable = no

[replicated_data]
vfs objects = fruit acl_xattr shadow_copy2 glusterfs
acl_xattr:ignore system acls = yes
acl_xattr:default acl style = windows
glusterfs:volume = replicated_cifs
glusterfs:logfile = /var/log/samba/glusterfs-replicated_data.%M.log
glusterfs:loglevel = 7
kernel share modes = no
path = /replicated_data
read only = no
guest ok = no
create mask = 0660
directory mask = 0770
map acl inherit = yes
inherit permissions = yes
inherit acls = true
store dos attributes = yes
shadow:snapdir = /.snaps
shadow:basedir = /
shadow:sort = desc
shadow:snapprefix = snap_replicated_cifs
shadow:format = _GMT-%Y.%m.%d-%H.%M.%S


_dispersed volume:_

[gluster-dispersed_cifs]
vfs objects = fruit acl_xattr glusterfs
acl_xattr:ignore system acls = yes
acl_xattr:default acl style = windows
glusterfs:volume = dispersed_cifs
glusterfs:logfile = /var/log/samba/glusterfs-dispersed_cifs.%M.log
glusterfs:loglevel = 7
kernel share modes = no
path = /
read only = no
guest ok = no
browseable = no

[dispersed_data]
vfs objects = fruit acl_xattr shadow_copy2 glusterfs
acl_xattr:ignore system acls = yes
acl_xattr:default acl style = windows
glusterfs:volume = dispersed_cifs
glusterfs:logfile = /var/log/samba/glusterfs-dispersed_data.%M.log
glusterfs:loglevel = 7
kernel share modes = no
path = /dispersed_data
read only = no
guest ok = no
create mask = 0660
directory mask = 0770
map acl inherit = yes
inherit permissions = yes
inherit acls = true
store dos attributes = yes
shadow:snapdir = /.snaps
shadow:basedir = /
shadow:sort = desc
shadow:snapprefix = snap_dispersed_cifs
shadow:format = _GMT-%Y.%m.%d-%H.%M.%S

Any help or hints are appreciated to resolve that issue.

Thanks in advance.
