Greetings,
I have a samba server deployed.
The machine has these:
cpu: amd64 -4 cores
motherboard :GA-990XA-UD3 with 6 sata ports and
StarTech 2 Port SATA 6Gbps PCIe SATA Card
memory: 16GBytes
disks: raid 10 (6 disks)
os: cblfs/linux kernel-3.1.5 pure 64bit and samba-3.6.0
The machine in deployed as a data-storage-device for windows7-based
machines doing 3d graphics rendering using
3d-StudioMax. There are 8 client machines with plans to expand this to ~20.
The rendering machins do frequent writes and reads to the samba server which
also runs linux software raid (RAID10). The smb.conf has these:
[global]
workgroup = WORKGROUP
netbios name = WHATEVER
server string = Samba %v on (%L)
encrypt passwords = True
security = user
smb passwd file = /etc/smbpasswd
log file = /var/log/sambaUSER-log.%m
socket options = IPTOS_LOWDELAY TCP_NODELAY
hosts allow = 192.168.0. 127.
host deny = 0.0.0.0/0
interfaces = eth* lo
bind interfaces only = yes
dos charset = cp850
unix charset = ISO-8859-1
load printers = yes
max log size = 50
local master = yes
printing = cups
guest account = guest
os level = 99
dns proxy = no
wins support = yes
#[ipc$]
# hosts allow = 192.168.0.0/24 127.0.0.1
# hosts deny = 0.0.0.0/0
[homes]
comment = Home Directories
valid users = %S
read only = no
browseable = no
[printers]
comment = All Printers
path = /var/spool/samba
browseable = yes
guest ok = yes
printable = yes
browseable = yes
writable = no
create mask = 0700
public = yes
there is no firewall yet
It is a new setup and the server is crashing daily. We do not know the cause
of the crashes but here are some unusual ways the server us currently used:
--a) because of work pressures 8 users are logged in with the same name to
write to a publically accessible share. Could is be the cause of the crashes?
--b) Could there be a mismatch of sata types as the startech sata card
though rated as the same 6Gbps transfer speed as motherbard-integrated raid ,
is a different asic AND IF SO could this be causing the problems?
--c)Are there settings in smb.conf which can increase the data-transferred
rate vin the eternet ( bonding NIC's for example) and if so how so.
Advice would be much appreciated.
sincerely
