DSM-G600, DNS-3xx and NSA-220 Hack Forum

hi,
you can follow my posts in the following link,
there is another guy having problem with linux and has recently been successful following my guide
http://forums.dlink.com/index.php?topic=11631.0

if you can live with the write performance impact you can skip these steps
the steps are applicable for standard and in fact any configurations as long as you are using WDxxEARS

Do you need to do this if you use standard (non-raid) disks?

I dislike any performance losses, especially given the relatively slow transfer speeds of the DNS-323 that I have.  About how much is the performance degradation, have you been able to quantify it?

Many thanks.

I was unable to get the swap partitions to unmount, tried using the minimal telnet fun_plug but i couldn't get it to work, made sure starttelnet.sh was chmod a+x...

in the end, I was able to boot funplug from USB and umount the raid then redo the main partitions to be divisible by 8.   Think there will be a huge performance slowdown with the swap partitions being misaligned?


Edit:

Of course the DNS-343 didn't remount the RAID on reboot... hope it isn't redoing my partitions while it reinitializes/formats....  Will report back later!

Well i got it to work!  Was able to follow timezlicer's directions and repartitioned all 4 swaps and sd*2 partitions to make them start aligned/divisible by 8... Should hopefully be right! 

I reassembled and formatted the RAID 5 and after reading about manually using mdadm on the 323 forum, I got my RAID running and used the 'raidstart' to make sure the right /tmp files were left so it would survive reboot...

Prior to rebooting I checked the web-interface and it was reporting my raid as being healthy and was able to copy back the fun_plug files...

Of course, life can't be so easy... The Raid did not restart upon reboot....

I have no idea where to go from here and now that I can't get it to show up, I can't even boot up with fun_plug to try and fiddle around.  I know the RAID is good and it was reporting and running properly before reboot...

Any ideas what I can do?  I really don't want to go through this whole process again as it took quite a few hours to do and even after giving proper partitions, DNS-343 redoes them when you setup a raid again through the web interface....

ARGH!!!! >  Of course the WD EAD drives are all sold out so I can't even try the easy route, I'm stuck trying to get these 4k bastards to work with my raid... Any hints what to do next?  I could always just hope I never have to reboot... >  I got an UPS at least....

*sigh*

I bought the 2 TB EARS and was going through your instructions before performing the upgrade. In short, as I wrote at http://www.consumedconsumer.org/2010/05 … -tb-i.html ,  I installed the drives and even run a benchmark test - no problems so far. I will be reading a bit more on 4K, as it is not clear to me exactly how do the need to be partitioned and why - more precisely, should I partition exactly as in your example?

I'm also thinking to mount the new drives under Linux, and partition there with parted, as I need to copy all the files from the RAID anyway. That should not be a problem, correct?

You can follow you own way as long as the size on the raid paratition is ok.
I've not change the size before but I think it should be ok.

I've recreated the utelnetd-ramdriver version.
Hope that it will help you.

This guide is made for DNS-343
Someone told me that 323 is having on the most important command write_hdverify
Please help to check...

hi timezlicer,

I am new to linux and have dns-323 and 2 x 2TB WD EARS.  I am a bit stuck on the fdsik part.  I was able to telnet to my dns-323 but can't seem to run fdisk.

here is the msg  from my terminal.

jeff@xbmc:~$ telnet 192.168.0.192
Trying 192.168.0.192...
Connected to 192.168.0.192.
Escape character is '^]'.
stdin, stdout, etderr: 0 1 2


BusyBox v1.2.1 (2006.10.30-10:27+0000) Built-in shell (ash)
Enter 'help' for a list of built-in commands.

# /tmp/fdisk -lu
/bin/busybox3.dir/sh: /tmp/fdisk: not found
# ./fdisk -lu

what am i doing wrong? Any help would be appreciated thanks.

PS it didnt even ask me for  5784468 pass it just gave me the #.

i am on the 1.08 fwfordns-323.

my starttelnet.sh:

# improved starttelnet.sh, enabling the filesystems to be unmounted and checked, if need be.

# copy the provided components to a directory on the ramdisk
# the ramdisk is regenerated with every boot, so the copy has no lasting effects at all
# simply copy the two files over
cp /mnt/HD_a2/lnx_bin/utelnetd /sbin/utelnetd
cp /mnt/HD_a2/lnx_bin/busybox3 /bin/busybox3
cp /mnt/HD_a2/ffp /ffp
cp /mnt/HD_a2/fdisk /tmp/fdisk

# create the terminal device as usual
/bin/busybox3 mknod /dev/ptyp0 c 2 0
/bin/busybox3 chmod 0666 /dev/ptyp0
/bin/busybox3 mknod /dev/ttyp0 c 3 0
/bin/busybox3 chmod 0666 /dev/ttyp0

# make a shell link on the ramdisk
mkdir /bin/busybox3.dir/
PATH="$PATH:/bin/busybox3.dir"

ln -s /bin/busybox3  /bin/busybox3.dir/sh

# and start the Telnet service from the ramdisk as well
/sbin/utelnetd -l /bin/busybox3.dir/sh -d



Thanks alot again.

thanks InBonobo......

didnt work tho

have two single disks in my NAS. The main disk (HD_a2) is formatted correctly, having 3 partitions. The secondary disk is new. Do I really need the 3 partitions there, or can I just create 1 big (aligned) partition?

UPDATE: I guess the firmware really needs it. Just having one partition will trigger the firmware/web interface to reformat the disk!

i tried my VERY best to understand the instructions.... but i just can't get it to work...
i have the 2x wd20ears in a DNS-323 on a gigabit network.  upon installing the drives and formatting to raid0, i did a benchmark and i was getting 16MB/sec write and 19MB/sec read.  this is without aligning the partition (cuz i can't get it to work).

i did some reading, http://sd.wareonearth.com/~phil/jumbo.html
then changed the jumbo frame rate from default (disabled) to 9KB.... and now i'm getting 19.3 MB/s write and 31.5 MB/s read.

will i see further speed improvement if i align my partition? what do i have to change from timezlicer's instructions to align my raid0 partition?

thank you

Hi,

I have run Intel's NAS Tester before and after the alignment because I obviously wanted to see the effect. The benchmarks are not "scientific" but do provide a better overall picture than the other benchmarks that I have found.
