Guru Plug Server Plus advisory needed ... :)

[slippy]

Hey there,

I'm pretty new to all that plug computer stuff. Today my pre-ordered guru plug server arrived and it's amazingly small Anyway ... first I thought "damn, there's no manual - but what the heck ... who needs a manual at all?!" So I began connecting the server and tried to find my way on it - successfully!

I just read about overheating and stuff - I cannot copy that. It runs smooth, hand-warm, with the ethernet cable connected all the time it's being powered on.
So perhaps I received one with an already fixed power supply?! ... Whatever ...

Okay - my questions: As I do not want to brick my plug before I begin to use it, I'd like to know how I could make a backup of the NAND ... and ... if this is possible ... how could I mirror that OS from the NAND to my mini SDHC 4GB card? If this is not possible ... how can I install a fresh OS on my SDHC and boot from it? Are there some tutorials on the net for this? As said I'm really new to this topic ... any advise is highly appreciated

Thanks in advance.

Cheers!

Hmm is your hand hand-warm at the normal human temperature between  35,8 and 37,2 °C (96,5 to 99 °F)?
Then my GuruPlug is also hand-warm...but with this temperature 10 °C warmer as my SheevaPlug....

My GuruPlug Plus runs now after some days from 35 to 39 °C with one Conenction at eth0 and WLAN enabled.

Hi,

Okay - my questions: As I do not want to brick my plug before I begin to use it, I'd like to know how I could make a backup of the NAND ... and ... if this is possible ... how could I mirror that OS from the NAND to my mini SDHC 4GB card?

I would suggest making a backup of your rootfs, using tar - I suppose this should be enough to restore the system state. (at least for the SheevaPlug it is enough - as long as the kernel is not changed)
To make that backup, connect a USB-Stick or MicroSD card to your plug and run the following:

Code:

tar --one-file-system-cvzf /media/usb/rootfs-backup.tar.gz /

This should create a file called rootfs-backup.tar.gz on your SD card/USB stick.

If this is not possible ... how can I install a fresh OS on my SDHC and boot from it? Are there some tutorials on the net for this? As said I'm really new to this topic ... any advise is highly appreciated

As far as I can see, the GuruPlug should be related closely to the SheevaPlug. For the SheevaPlug there are already tutorials (e.g. here: http://plugcomputer.org/plugwiki/index.php/Debian ) which could help. I haven't tried them yet, as I'm heaving... err... issues with my GuruPlug (getting hot, endless reboot loop, when connected to GBit etc...) But with the SheevaPlug I always started with a prepared clean rootfs-image and then used apt-get to install whatever I needed.

Cheers!

Thanks for your answers ... I'm going to do a backup of the rootfs on my USB stick asap so I can begin playing around with it

Hand warm is normal body temperature between 35,8 and 37,2 deg celsius - meanwhile I figured out by reading a whole bunch of threads that this overheating issue obviously relies on the usage of GB ethernet - I don't have that atm ... this could explain things - although I planned to buy a new switch ... but I think I'll wait with that

I'm still unbelievable amazed about that plug server(!) - it's really awesome!

Cheers
