hi

im having trouble loacating and accessing my dlink after b7 install

i was running b6 (on top) and i just installed (on top) b7, now i may have used used the old fun_plug not sure now, wasnt paying enough attention i guess

The new fun_plug only has a new fail-safe mechanism, interfering with nothing else.

with b6 i had set a static ip of 192.168.1.11  and now that ip reveals nothing, cant see dlink in network map either (win7)

If you have saving settings, then IP should be the same.
Have you tried to direct your browser to the box, typing "http://192.168.1.11" as the URL?
Have you tried to use the command line to "ping 192.168.1.11"?
If you use DHCP in your network, have you see you DHCP (usually the modem/router ) for any client?

i believe it worked, as the LED looks like it used to and holding the power button gives the orange blink on one then other drive

That is a good indication that everything is running fine. You only have to find the box ip. Does 'nmap' exists for MS-windows?

but for the life of me i cant reconnect to it. also i have HEAPS of data still on drive that i dont really wanna lose.

also reason i went to alt-f is original firmware was playing up so i dont really wanna have to rely on that cause dont know how it will work after all this time

any help would be much appreciated. side note: i am a beginner at this linux stuff

Thanks

hi

yeah  thats what i meant, typing 192.168.1.11 into browser only gives me "oops google chrome could not connect to 92.168.1.11" obviously im using Chrome

ping cmd gives me  "destination host unreachable" tho in ping statistics it say 4 packets sent and 4 received

HAHA  your dhcp comment reminded me where the table is on my router, so i just searched that and it seems all my devices have moved into 192.168.1.100 range, not sure why but at least now i know

from that i have found the dlink ip, box ip has moved to .113, and since setup everything i need

time to test out minDLNA with my googleTV

Thanks jcard you're 3 kinds of awesome

Please look at following output:

and compare it with attached picture.

Size of /dev/sdb2 is different. 3904939697 vs 2147483647

Is it bug or feature?

A bug, discovered (and fixed) some time ago.
The problem was that I only had a 1TB drive to test with, and very long numbers (number of sectors on partitions greater that 1.2TB) where truncated.

I am starting out with two new WD20EARS drives and was wondering whether the ext4 format will provide any performance advantages over ext3. I have read various articles on this, and was wondering whether any Alt-F users could share their experiences using the most recent release 0.1B7.

My intention is to take the safe option in the first instance and format the disks using the DLink firmware (1.09) and then install the Alt-F in a reload setup and then format as ext4. I see in previous posts in this thread that other users have the WD20EARS drives, and users experiences on these drives would also be appreciated. I have seen a number of posts in other forums about the issues with these advanced format drives

Regards, Grant

Thanks for the quick response João. I found your performance page very interesting, particularly the performance of the 2 internal disks and an external USB in RAID5 configuration.

With respect to the issues with the DLink firmware, I note that 2Tb and ext3 support only came with firmware version 1.08 in February 2010. The current DLink version, 1.09, is running a kernel based on 2.6.12, so I'm wondering whether the issues reported by others using the WD20EARS and the DLink firmware are related to the fact that the newer disk technologies in the EARS drives are running in a version of the kernel first released in June 2005. I note that your 0.1B7 is running on a 2.6.35 kernel base which, I suspect, will handle the newer technology drives.

All is conjecture at this stage, and unfortunately I haven't had an opportunity to test your most recent firmware due to work commitments. I note the point about the  disk partitioning page bug, so in order to format a 2Tb partition I will use the disk wizard web page. I will report back on my progress. Keep up the great work.

You might be interested reading my findings in Alt-F regarding filesystem/raid relative performance:

http://groups.google.com/group/alt-f/br … e775f6ead#

B7 disk partitioning page has a bug that does not allow bigger than 1.2 TB partitions. The disk wizard web page does not suffers from this problem (I was told)

Does 1.09 from dlink 4k aligns partitions? Alt-F does. (you say you will be using WD20EARS, which has 4k physical sectors. If partitions are not properly aligned write speed will suffer)

I finally managed to get some time to get my NAS installed and I have to say that so far the process has been painless. Thanks again for all your assistance, and of course all the other posters to the various forums. All the information supplied has been most helpful.

I adopted the strategy of installing the bare minimum required on the DLink firmware in order to get Alt-F installed. For safety I initially installed Alt-F on top of the DLink firmware. I have a B1 board, so after testing whether I would be making a brick, I flashed the firware to Alt-F-0.1B7. I rebooted and then reformatted the drives to ext4 in a RAID1 configuration.

Some observations about the process. Startup on Alt-F is faster than DLink and I couldn't format to ext4 while using Alt-F on top of DLink only after flashing. In answer to the question about the DLink and 4k alignment, I actually didn't check that because I jumped straight over to Alt-F. With respect to the disk partitioning, I used the disk wizard and it worked correctly.

im having a little problem

i had a power outage this morning, and im running "over the top"

so i am now back to the original firmware, now i have tried to reflash B7 back on my NAS

but i cant seem to set the execute permission of the funplug, it tells me Access is denied

and no matter how or where on the nas i try to change permissions im told access is denied

any ideas?  once i get this working i think i will flash permanently   

Thanks

RellikZephyr

EDIT: deleting and copying fun plug back on seems to work, copy and replace does not

now i just gotta wait for disk check...hmmm 60% full 1.5TB drive might be here a while

EDIT 2:  after disk check. i cant seem to access any of the files on nas. i remapped network drive (cause if new ip). i can see the files, but whenever i try to access them
it tells me it is not accessible.  i have turned on the samba server. also side note  i cant seem to activate dlna server ushare

please help

Thanks for cfw. Flashed Alt-F-0.1B7 into DNS-323 B1 and all went fine. I have two separate WD20EARS 2TB drives formatted in ext4 fs.
1.With dlink 1.8 ofw and samba my network throughput between nas and my stationary pc was about 10-12 Mb/s. Jumbo frames was on. Now i have only 2 to 5 Mb/sec. Jumbo frames also on. Is it worth to change samba for nfs or to tweak samba somehow? Why so slow?
2. Can cfw turn off a bright blue power LED? Ofw 1.8 has this ability.
3. With ofw 1.8 my Smart UPS APC 620 with serial interface works fine. I used compiled modules pl2303.ko and usbserial.ko. Are there precompiled modules for cfw kernel or i need to compile them myself?
4. /dev/sdb won't spindown while transmission downloading files at /dev/sda

When will be the next stable release?

Hi,

I found this release: 0.1RC1-snapshot (http://dl.dropbox.com/u/1555717/DNS-323 … index.html)

How stable is it? is it compiled from r1114 ?

Greetings

but is 0.1RC1-snapshot stable enough for daily usage?

or do you recomend 0.1B7?

it would be great to have GPT support, keep up the good work!

Do you have any idea when 0.1RC1 will be released?

2-5 mpbs is too low. But Alf-F is not faster then the stock firmware.

Have you reboot after setting-up Jumbo frames? Setting high MTU values during operation can effectively degrade performance, see issue 19, "Jumbo frames make linux start swaping" http://code.google.com/p/alt-f/issues/detail?id=18

Also, a MTU greater then 3700 or 7500 stresses the memory allocator for a machine with only 64MB of memory. Perhaps the vendor's firmware uses a different or patched memory allocator, or the network driver is a proprietary one?

ext4 versus ext2 does not explains the lower smb performance, see topic "Filesystem and disk layout performance on 0.1B4" in http://groups.google.com/group/alt-f

I have not yet done any comparable and reproducible network/disk tests, such as using 'netcat' for pure network performance and for network+disk/fs performance. It would be interesting if someone does it.

I've made some samba tweaks and tests. Still low speed, then i just tried nfs and, voila, 10-12 Mbps! So i'll stay with nfs for now.

echo 1 > /sys/class/leds/power\:blue/brightness # turn off
   echo 0 > /sys/class/leds/power\:blue/brightness # turn on

Or do you mean the network led? It is controlled by the network driver, I'm not sure if we can turn it off.

That did the trick, thank you. I've put this in startup script.

Currently there is not kernel-modules package, so you have to compile the modules yourself, or open a request.
added: Anyhow I added usb-serial support (with no chip-specific modules) for the next release.

Thanks a lot! I hope prolific 2303 chip will work.

Have you installed Alt-F packages in some filesystem in the sdb disk? Then it is used for packages binaries and log files, and won't spindow. You can try to uninstall all Alt-F packages and reinstall them in sda (save configuration files first).

Also, swap uses both disks in parallel, if swap is being used and paging occurs, the disks will not spin-down.

Please request one of my "Lectures" on this subject, if you really want to :-)

Yes. I've installed transmission in /dev/sda.

Hey jcard i'm wondering if your back again and working on this. I look forward to flashing ALT-F but i don't think its do for prime time yet and still needs more work.

Keep up the good work. Hoping to unlock the full potentials of the my shiny NEW DNS-323 i got a few days ago
