Hi. I'm running armbian on a OrangePi PC 2. This is my uname -a output:

root@picard:/lib/modules# uname -a
Linux picard 4.18.0-rc8-sunxi64 #30 SMP Mon Aug 13 00:57:56 CEST 2018 aarch64 aarch64 aarch64 GNU/Linux

 

I am running LVM2 on that system. I updated today, and the dm-raid kernel module seems to have gone missing. I can't get my LVM volume group up anymore, since it can't find dm-raid:

 

root@picard:/lib/modules# lvscan 
  inactive          '/dev/vg-data/lv-data' [2.70 TiB] inherit
root@picard:/lib/modules# lvchange -ay vg-data/lv-data
modprobe: FATAL: Module dm-raid not found in directory /lib/modules/4.18.0-rc8-sunxi64
  /sbin/modprobe failed: 1
  Cannot read target version of RAID kernel module.
  Can't process LV lv-data: raid1 target support missing from kernel?

I have already switched my kernel using the armbian-config 'switch' function (from 'next' to 'dev'), which doesn't seem to make a difference.

 

How do I get that kernel module back? Thanks for any help!

Hi. I'm running armbian

 

You are running an unsupported development kernel and you didn't supply the most important information:

armbianmonitor -u

to help you get back to the stable builds.

Sorry about that! I think the kernel (before I switched to 'dev' using armbian-config) is the one that came with the image for the Orange Pi PC 2…

Thanks for your help.

I doubt rarmbian-config can not make such a mess. Start with a clean image or clean the mess  

 

Remove: 

apt purge linux-image-dev-sunxi64 linux-dtb-dev-sunxi64 linux-xenial-root-dev-orangepipc2 linux-u-boot-orangepipc2-dev

and switch back to stable. If you fail ... start with a new image.
