Thanks for your polite response.  Note that after that very strong
statement you make, you then go on to (correctly) identify the very
specific situations where dd *does* actually work.

Thanks for your commentary.

That statement is completely absurd.   "dd" always works when copying
filesystems, provided you use the correct block sizes.   System administrators
have been doing this to backup filesystems for more than 30 years.   I have
personally been doing it for more than 15 years, and I have never had problems.

That said, chances are the problem is not copying the filesystem, but the disk
image.  e.g.

dd if=/dev/sda1 of=/dev/sdb1 bs=2048

works ok.  But

dd if=/dev/sda of=/dev/sdb bs=2048

will only work if both hard drives have the same physical partitioning.

However, you can still recover the data by dd'ing back to the original drive if
you erased it...

That said, I do NOT advice using dd to copy filesystems unless they contain
features not supported by higher level programs.  Usually "rsync" is both faster
and better.   However, a common exception to this rule is when copying the root
partition of a file system with SELinux enabled.  "dd" will preserve all the
SELinux settings, "rsync" even with the appropriate settings might not be able
to.

I also tend to use "dd" when backing up windows partitions.   The reason being
is I've yet to find a linux method of copying windows file systems that
preserves windows ACL's and such.   Meaning if I want C: drive to boot and
start, I better copy it with dd.

Thanks for the tip. Without drives connected the slug boots as you said it
would, and I can ssh to it. At this time I'm copying the old disk to the new
disk using my laptop running clonezilla.

We'll see what happens when I reconnect the USB drives.

Unplug everything from the USB ports, then boot up the NSLU2 -- if it is
running SlugOS, it will boot up and you'll be able to login to the
device.  Now you can plug in the external disk -- check the messages
(dmesg) and see if it detects it and mounts it.  Fix whatever is wrong
until it mounts.

Hi,
So, I wanted to upgrade from my 750GB Hitachi to a 1TB Fantom. I plugged the
Fantom in to the 2nd USB port and started dd. After 15hours I controlled C the
dd, shutdown the slug and powered it off. I took the drives to a laptop and
planned to copy them from there, but the Fantom would not be recognized - seems
like others have this problem.

Ok, I thought, plug the 750GB back in to the slug and go with that - no big
deal. However, the slug beeps, flashes the lights then does nothing. I left it
for many hours and the ethernet flashes green, the top led flashes yellow (with
a tint of red). I disconnected the power - reconnected the drive to a laptop
running linux and ran ext3fs - which completed OK.

Reconnected the drive and powered on the slug - again after 12 hours or so,
still the same flashing LED. I think the slug is running slugos.

Any thoughts on what I can do get the slug working again?

Thanks,
Bryan.

The NSLU2 was discontinued in the spring of 2008, more than 18 months ago.

       Dear Group,



I tried today to order some new nslu2 units.

My supplier told me they where out of stock, and he could not deliver them
anymore.



Does anyone know if the nslu2 is still produced (or in stock) by linksys ?



Does anyone have a supplier ?

I nomaly pay about 60-65 Euro excluding Vat.

We are located in the Netherlands.

The NSLU was discontinued by Linksys in 2008
http://en.wikipedia.org/wiki/NSLU2

You can still buy them new and used, though it looks like prices are
creeping up slowly

[Non-text portions of this message have been removed]

Nope, they are end of line/end of life (EOL)

Most people are buying SheevaPlugs now, though, some NSLU2's can be bought on
eBay and alike.

Hello!
Do you mind if I ask which supplier you chose? It happens that I buy a heck
of a lot of electronics via Amazon (then from Staples). I suggest you try
searching the localized Amazon pages to see if you will have (much) better
luck there.

And I still suspect someone at LinkSys (before they were officially part of
Cisco) to be morally bankrupt for discontinuing the NSLU2 before they had an
actual replacement.

(Just my opinions and valid only in the US.)

Dear Group,

I tried today to order some new nslu2 units.
My supplier told me they where out of stock, and he could not deliver them
anymore.

Does anyone know if the nslu2 is still produced (or in stock) by linksys ?

Does anyone have a supplier ?
I nomaly pay about 60-65 Euro excluding Vat.
We are located in the Netherlands.

Personally, I've tried several times to format a disk with the slug, but it
always failed (it says "formatting", but never completes). Best to format it on
another linux box.

Paul.

I've had my NSLU2 unslung previously but was having problems setting up my Media
Server and decided to start over from scratch. Everything seemed to have gone
alright (I'm using 6.8 Beta). Booted up, got into GUI, telnet enable, telnetted
in, after root, uNSLUng I get "No Directory, logging in with Home =/, Welcome to
unslung v2.3R63 - uNSLUng 6.8 Beta. I connect my disc (disk1) check GUI, format
Ext3, unsling disk1, waiting for /share/hdd/data and it then goes through
countdown and fails to unsling. The fact that it is 1:00am and my brains are
fried might be contributing to it but if there are any suggestions I'd be
greatful.


Thanks,

Paul

Thought I'd follow up on this in case anyone's interested.

Tried a newly formatted NTFS disk in the new USB box. The only way it would work
was if I removed the unslung stick and booted from ROM. After a lot of hours
experimenting and much swearing, the only solution was to connect the disk to
another machine and format it to ext3 and when connected to the slug it has to
be mounted manually (port 1) as sda1. I have the unslung stick sharing port 2
with the printer via a hub. The new disk shows up in the web server as
unformatted, but it's now working fine as a scp backup drive.

So it's a mystery.

the drive has suffered, because I've now connected it via USB to the XP box and

reformat the disc and start afresh. Dmesg threw up lots of errors on the slug as
well, so poo.
