Distro: Debian Sarge
Kernel 2.6.8
Samba 3.0.7-2
Processor: Pentium4 3.0Ghz
Motherboard: Asus P4C800
2x40GB Seagate 7200RPM in Software RAID1 for the system.
Highpoint Rocketraid 1640 Raid Controller + 4x200GB Software Raid5
Driver: hpt374-opensource-v2.12
I tried to make the Highpoint's RAID5 work using
hpt374-opensource-v2.12 and Highpoint Management Console but I always
get a Kernel Panic everytime I start to copy files to the RAID5
Volume, So I decided to use Linux Software Raid but still using
hpt374-opensource-v2.12 driver because the default drivers can only
detect the 2 SATA drives properly.
The speed of samba is very slow compared to our windows 2003 file server.
Here's the result of my testing:
from my workstation to samba server (627MB iso file) = 8mins 20sec
from my workstation to win2003 server (627MB iso file) = 1min 17sec
So I did a benchmark of the RAID5 volume using bonnie++ (bonnie++ -u
root -b -d /RAID5A -s 4g -m category -n 128:20000:16:512) here's the
result:

here's my /etc/raidtab:

raid-disk 0
device /dev/sdd1
raid-disk 1
device /dev/sde1
raid-disk 2
device /dev/sdf1
raid-disk 3
My smb.conf is almost all default but I already included socket
options = IPTOS_LOWDELAY TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192.
I'm not so familiar with disk benchmarks but comparing to this
http://oregonstate.edu/~kveton/fs/page2.php the result seems low. Any
help would be greatly appreciated as I need to make this work asap
because our Windows 2003 File Server (300GB) is almost full :-)
TIA,
