Domoticz

People,
When I maken a copy of the sd card I’am using in the RPi with Domoticz it is not usable in another raspberry.
It seems to be dedicated for his used RPi.
How can I make a copy it (app and his commands) so the SD card can be used in other raspberrys (with all the specific RPi and Domoticz settings and used scripts in crontab)?
Regards

Hi! I use Applepi Baker program to do the copy exactly like original. But to get it works, is necessary that the original and the copy cards have the same capacity and brand, why this? Because between different brand, sometimes there are small differences in capacity.

Dear i000,
Does the copy works then on the same RPi or a different one.
Because thats the problem to make a copy and let it work on a second different RPi (caused by addressing and so on).

I use etcher to copy the SD but befose doing any copy I use also to close the PI not with shutwon but Halt


sudo halt

Hi,

What exactly is not working using a copy?
Do you get errors?
And also, you mention addressing, do you mean you get messages about duplicate IPs?

Can't you just attach the second sd card to your Raspi (through a USB adapter) and copy it literally:

dd if=/dev/mmcblk0 of=/dev/mmcblk1 bs=16M

(take mmcbkl0 and mmcblk1 according to your own settings)

Hi NetEye, for me is a Backup. To work in a second is necessary change the fixed IP address, but I have this working always with the same to access remotely.

I will trie it.
One on one back-up and change ip adress.
Thanks all

I can not get it right.
I made it as : https://medium.com/a-swift-misadventure ... 8a630f899c
When I put it in a different new unused RPi it does not work.
Like there is no operating system on the raspberry.
The green and yellow lights of the RJ45 utp connection is not lighting...no connection

When you connect your pi to a monitor do you see any errors. When using the copied sd I guess yoy have diconnected the original one to prevent ip conflicts?

Just to be sure, are you formally cloning the card using a card-copying utility (e.g. Etcher) or just dragging files over from the source card to a newly formatted card? That will never work if that's what you did...

hm, good question. I duplicate my SD-cards with win32imager, off-line

Yes Phil I removed the sd card from the rpi and made a copy of it with Disk Utility app on my mac.
Save it in DVD/CD master Format and change the .cdr extension to .iso
Then an empty sd card writing the image with Etcher.
But it does not work yet, no communication possible with the rpi.
It is for sure my incompetence but hopefully I’am close.
Win32 imager does not work on mac i think, maybe I have to try it on a windows pc??

Connecting a monitor and checking the errors is a way to go from here

Not sure your imaging stuff makes a raw binary image...

Macs have a BSD-Unix base, so they should have the dd command...
Just take care not to invert of/if arguments while imaging or dd=data destroyer.

Also make sure to use the right device, not your HDD seen as a storage media just like the SD.

On Linux, if /dev/sdX is the device allocated to your SD, this should be something like (with admin rights, revert if/of, taking care of device name, to restore):

dd if=/dev/sdX of=imagePi.bin bs=1M oflag=dsync conv=notrunc status=progress

status report may not be supported (dd stays silent until the end... even if a USR1 signal on the dd process PID could be used to get status) on old versions.

As I didn't used an Apple device since a very long time (well, a nice brand that started in a garage making first hardware open to customization/add-ons now building such overly closed shit even impossible to repair, really impossible for me to buy this!), Apple IIe to make things clear, can't help more!

I will look for another way to clone.
I will leave the apple in the tree....

I’ve been using rpi-clone to make backup clones of my pi’s sdcard, on the pi itself, using an USB sdcard adaptor for the target. Internally, it uses a combi of dd and rsync and it imprements logic to be a bit smarter than plain dd, both in terms of speed and in it’s ability to clone a running system (aka ‘hot clone’)
