[solved] BananaPi Pro: boot directory still on sd card after moving to sata ssd

[jofland]

System: armbian, BananaPi Pro, sd card, sata ssd, usb hdd

 

I manually moved my existing armbian system from sd card to a sata ssd. Then I changed the rootdev in armbianEnv.txt to the ssd´s UUID.

 

After reboot I thought everything was ok. Then after a system update I figured out that the kernel version differs from the installed kernel modules.

 

I think the new kernel and the modules are installed in /boot at /dev/sda whereas the kernel still boots from /dev/mmcblk0p1.

 

How can I fix this?

 

 

Here some information:

I didn't know about that before I did the manual way. I think I can't use it anymore because the target partition will be wiped.

 

So I am looking for a manual way to fix my problem. Any ideas?

Did you know about Recovery section of Docs?  Maybe there is something helpful in there.

Interesting docs. I didn't know.

Unfortunately I don't think anything fits for my problem except creating manual symlinks between the boot directory on sd card and ssd. But is this a solution that survives the mext kernel update?

 

My problem is, the boot process uses the boot directory on sd card. The system uses the one on the ssd e.g. for storing updated kernel files.

 

How can I point the boot directory from sd card to ssd?

[jofland]

I solved it by my own:

 

I had to mount the boot directory of the sd card over the boot directory of the ssd. Therefore I added two lines to the /etc/fstab of my ssd:

 

/dev/mmcblk0p1  /media/mmcboot           ext4    defaults,noatime,nodiratime,commit=600,errors=remount-ro,x-gvfs-hide    0       1
/media/mmcboot/boot  /boot           none    bind

 

(had to create the directory /media/mmcboot first)

 

Now the kernel loads in the right version. Kernel update works. Topic can be closed.
