Hi everyone, I would like to ask for support if possible.
I have been using OH for a few years, today the version in use is 4.3.0.M4 on Raspberry Pi 4 Model B Rev 1.4.
I would like to ask if it is possible to copy/move the entire installation, including the persistence archives, on a new installation made on an old MacBook Pro with Intel i5 8GB 2.6GHz, which works and which I have just reset from scratch.
Is it enough to move/copy some files folders? If so, which ones exactly? and with which paths?
Is it enough restore the last backup from RPi?
I am not a computer scientist, I usually make do with the resources of this community.
Thanks for the support.
Hi, thanks for the reply.
I prepared the mac with a fresh installation of OH4,
it is set to start at startup and so far everything is ok.
With the RPi I was used to do the configuration via terminal with openhab-config,
but on mac how do I do it? I managed to access the CONSOLE,
but it is not the same thing … correct?
thanks
Ok, thanks, it’s clear,
reading the OH documentation I understood that it was like this,
but not being a programmer maybe I’m doing something wrong …
The question then is: on the mac how do I perform the “restore from backup” operation
that is available in openHABian-config?
thanks.
For completeness I add that all the configurations in openHabian I have always done only by working with text files (items, things, rules…) and I want to continue to do so also on this new installation… for me it is much more convenient…
ok thanks for the answer
I had the doubt of having stumbled upon this thing again,
I still haven’t understood the difference between the two,
I still have to study the documentation well
thanks
will open a shell on your server, giving access to the OS.
From there you can access openHABs Karaf shell by running
openhab-cli console
This is an application shell, giving access to openHAB specific command.
openHAB-cli with all its commands is available only on an OS shell, if openHAB was installed as package…
Hi, I’m really sorry but I don’t understand how to proceed.
I’m on my macbook, and OH is started by running the “start.sh” file, after which a Terminal window opens, which is the one indicated above.
And if I understood correctly it is the Karaf COnsole.
I opened another Terminal window and entered the command “ssh -p 8101 openhab@localhost”, and the result is the same, that is, the same screen…
So the question is: on a new Terminal window, what is the command to access what is indicated above, that is, the “normal terminal”?
Forgive my ignorance on the subject …
thanks
You first have to make a backup on your raspberry, using openhab-cli backup command.
copy your backup to your Mac, open a terminal and use the following :
cd $OPENHAB_HOME
./runtime/bin/restore /opt/backups/myconfig.zip ## Restores the openHAB config from the specified zipfile
./runtime/bin/restore --help ## Brings up the help information
No offense, but if you’re lacking fundamental understanding on how to use an OS and do stuff on a terminal, perhaps it’s better to learn this, before you move your smarthome to another hardware.
openHABian does a tremendous job to “hide” all those pesky tasks and stuff from the user. If you’re switching away from that you’ll basically have to learn how to deal with the tech “under the hood” and try to migrate/setup your openHAB on the same time.
Question is, why do you want to move to a macbook in the first place? is there a special reason for this? If OH4 is already running fine on your Pi I wouldn’t change the hardware without a good reason!
Perhaps we can help you find a solution, where you don’t have to learn all that system administrator stuff and achieve your goal?
Hi, thank you, I don’t get offended, on the contrary,
I am aware of being in the absence of knowledge …
My RPI works quite well, but sometimes we restart
and above all often when he asks me to update then he blocks
because he tells me that there is no space on the SD card.
I am terrified from losing everything
so I simply wanted to copy everything in bulk on this old Mac t
hat I no longer use and have a hardware for sure more performed and reliable for the next few years …
On Openhabian I am clear to me access to Cosole and from the Tertinal, but here on the Mac I do not understand how to connect to the “normal” terminal alone to give the backup/recovery commands … do I have to change a door? For example type “ssh -p 22 openhab@localhost” ?? Thanks for the support and scuate, if I can’t abandon and leave everything as it is …
just having an old macbook lying around doesn’t mean it will solve all your above problems!
if you’d like to stay on a pi (which btw works for a vast majority of openHAB users perfectly well):
1. random restarts
We’d have to solve this after the other problems. My guess is, it’ll stop, if there’s enough space on your Pi’s SD card. Sounds like the card is just full.
2. update problems
Blocking updates seem also to have the cause in running out of disk space on your Pi’s SD card
3. no space on SD card
now - THAT seem to be the real cause of all your problems. So I’d say, we solve that and you give the setup another try?
use the “raw copy SD” option on openhabian-config (menu 54: openHABian | openHAB)
use a USB-card reader in your Pi and use this menu. This will result in a exact copy of your current SD card.
Swap the SD cards and boot from the new one
Once your openHABian is on, run sudo raspi-config (similar to openhabian-config) and run “Advanced Options” - “A1 expand filesystem” => then the full size of the SD card is used
now you should have your openHAB-instance running on a new (and bigger) SD card.
4. losing everything
now, if everything is running you can spend some time on “backup”. easiest would be to do “manual backups” regularly within menu 50 on openhabian-config.
most popular options are:
SD mirorring: your internal SD card will be mirrored to an external SD card (just like in a raw copy, you did earlier, but automatically). So, if you experience trouble on your boot SD card you can pull out the mirrored one and just be ready in a sec.
a few other “home made” solutions… just have a look here in the forum.
I think, it would be easier to stay in your current setup with the Pi. you could always learn more about the terminal wit MacOs. (disclaimer: I don’t use a Mac, but this sounds like a decent course):
