boot + system incl. OMV from eMMC - howto transfer existing system from ssd to eMMC incl. configuration?

[greg396]

Actual booting from eMMC and system including OMV from Sata SSD. Running boot & system from eMMC should be possible now and I would like to transfer system from SSD to eMMC without losing my config and starting from scratch again. That way I'll have a sdd beside the hdd for OMV.

 

How can I manually transfer the system including OMV from SSD to eMMC and what configuration files need to be altered?

Why not use armbian-install?

Dear Werner,

 

I am booting without a sd-card and can use armbian-install with just an option transfering system from ssd to emmc and emmc won't be formatted?

Which option should I chose? boot frm emmc / system on emmc?

 

https://docs.armbian.com/User-Guide_Getting-Started/#how-to-install-to-emmc-nand-sata-usb

Armbian Installer support those storage scenarios:

boot from SD, system on SATA / USB

boot from eMMC / NAND, system on eMMC/NAND

boot from eMMC / NAND, system on SATA / USB / NVME

Boot from SPI - system on SATA, USB or NVMe

Install/Update the bootloader on SD/eMMC

Install/Update the bootloader on special eMMC partition

Install/Update the bootloader on SPI Flash

Install system to UEFI disk

 

thank you for clarification!

Not possible. emmc will be formatted before rootfs is copied over. If you have files there backup beforehand.

Since the rootfs is moved as it is you should not loose any configs.

I backuped the boot dir.

So I don't need booting from Sd-card, armbian-install will format emmc and copy from where the boot dir?

Afterward it moves the system to emmc.

 

If I am running armbian-config there's a message "Warning: The current OS (bookworm) is not supported or not listed"

it's the latest version

"Armbian 21.02.1 stable 6.12.32-current-rockchip64 (Debian bookworm)"

apt-get install armbian-config

armbian-config is already the newest version (25.8.0-trunk.330.0708.120916)

 

I can't see any option to install/update system
