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

Thr test I did under heavy writes all passed. I am unsure if it is kernel panics as I have not been on site when the reported crashes happen to verify. The reports are that it crashes under heavy reads. (i.e. up to 20 rendering computers are fetching files of up to 10 Gbytes each simultandeously ) But it does not crash under writes. Suggestions welcomed
