Re: Samba performance

also i think you should be able to get better performance if you use vfs_glusterfs [1]. From what I understand it's similar to samba what nfs-ganesha does for nfs, it uses the libgfapi directly rather than sharing a fuse-mount

[1] https://www.samba.org/samba/docs/current/man-html/vfs_glusterfs.8.html

on my test machine i did this: (centos 7)

first we need to install samba-vfs-glusterfs and of course the samba server which comes as a dependency:

yum install samba-vfs-glusterfs
gluster volume set vol1 server.allow-insecure on

now stop and start the gluster volume, this will auto-create a (non-working, how funny is that) configuration in /etc/samba/smb.conf gluster volume stop vol1

gluster volume start vol1

now edit /etc/samba/smb.conf and add kernel share modes = no and also guest ok=yes to the newly created [gluster-vol1] section so that it finally looks about like this:

[gluster-vol1]
comment = For samba share of volume vol1
vfs objects = glusterfs
glusterfs:volume = vol1
glusterfs:logfile = /var/log/samba/glusterfs-vol1.%M.log
glusterfs:loglevel = 7
path = /
read _only_ = no
guest ok = yes
kernel share modes = no

now restart samba

systemctl restart smb 

and now you should be able to mount the samba share

mount.cifs -o guest //gluster1/gluster-vol1 /mnt/cifs

Hello Anoop,

it is a known issue that Gluster+Samba has a poor performance especially for small files.
May this manual can give you more inspiration how to setup your Gluster and Samba environment.

This particular group command is only available from v6.0 (as of now).
