hi All,
We have a glusterfs cluster with 5 nodes on Ubuntu 12.04 amd64.
We use this smb.conf:
[global]
socket options = IPTOS_THROUGHPUT TCP_NODELAY IPTOS_LOWDELAY
SO_SNDBUF=131072 SO_RCVBUF=131072
read raw = yes
server string = %h
write raw = yes
#oplocks = yes
max xmit = 131072
dead time = 15
getwd cache = yes
use sendfile=yes
block size = 131072
load printers = no
aio read size = 16384
aio write size = 16384
aio write behind = /*.*/
wins support = no
local master = no
wins server = 192.168.3.7
veto files = /.AppleDouble/
delete veto files = yes
hide dot files = yes
printing = BSD
max protocol = SMB2
min protocol = SMB2
[projects]
path = /W/Projects
browseable = yes
public = yes
guest ok = yes
read only = no
force user = user
force group = user
The speed is fine with this configuration, around 100Mbyte/s. If I change protocol to NT1, the speed
drops to around 50Mbyte/s.
This is from man page:
NT1: Current up to date version of the protocol. Used by Windows NT. Known as
CIFS.
SMB2: Re-implementation of the SMB protocol. Used by Windows Vista and newer. The Samba
implementation of SMB2 is currently marked experimental!
Why is it still experimental? What does it mean exactly? Is there anything I should avoid it, like
file corruption or so?
Why NT1 is _much_ slower then SMB2?
Thank you,
tamas
