Hi everyone!

First thank you for providing this beautiful piece of software, Armbian rocks!

 

I am running Armbian 22.02 Bullseye on my Odroid HC4.

After booting I did 

apt update
apt upgrade

 

Next I went into armbian-config -> Software -> Headers_install

So I ended up with this configuration 

$ uname -a
Linux odroidhc4 5.10.102-meson64 #22.02.1 SMP PREEMPT Sun Feb 27 09:09:25 UTC 2022 aarch64 GNU/Linux

$ apt list --installed | grep meson64
linux-dtb-current-meson64/bullseye,now 22.02.1 arm64 [installed]
linux-headers-current-meson64/bullseye,now 22.02.1 arm64 [installed]
linux-image-current-meson64/bullseye,now 22.02.1 arm64 [installed]

 

Next, I tried to install zfs as per many posts:

https://forum.armbian.com/topic/17337-zfs-just-works-now-on-armbian-2-step-instructions-if-you-are-thick-like-me/

 

Only for it to fail with this error message: 

$ sudo apt install zfs-dkms zfsutils-linux
...

I found people dealing with similar problems and tried the suggested solutions, none worked.

=====================

1) https://forum.armbian.com/topic/18015-the-zfs-modules-are-not-loaded/


Here I followed the post where the user suggests to install the linux-dtb/image/headers manually. So I did just that, I downloaded these files and installed them with dpkg. -i. Source of files: https://imola.armbian.com/apt/pool/main/l/linux-5.10.102-meson64/

linux-dtb-current-meson64_22.02.1_arm64.deb
linux-headers-current-meson64_22.02.1_arm64.deb
linux-image-current-meson64_22.02.1_arm64.deb

 

And nothing changed when I tried installing zfs-dkms

=====================

2) https://forum.armbian.com/topic/15441-unable-to-build-zfs-module-on-buster-rockchip64/

Here I followed ShadowDance's guide, used an appropriate debian bullseye image, installed the headers downloaded from proposed solution 1) but it failed at 

# ./configure --with-linux=/usr/src/linux-headers-$(uname -r)
...
checking if modules can be built...no
...

 

=====================

3) https://forum.armbian.com/topic/14576-odroid-n2-zfs-header-issue-on-buster-kernel-56

 

Here Igor suggested to switch to Nightly builds. So I did, ran an apt update && apt upgrade, rebooted, tried to install zfs-dkms and it failed again with the same error message 

modprobe: FATAL: Module zfs not found in directory /lib/modules/5.10.102-meson64

It seems switching to Nightlies didn't change the kernels, as uname -a returns the same kernel version as above, so I guess it makes sense switching to Nightlies didn't solve anything.

=====================

4) I tried a few other 5.10.x-meson64 kernels via armbian-config -> System -> Other. After installing the kernel I'd ofc install the headers and retry installing zfs-dkms, just to be hit with the same "Module zfs not found".

 

=====================

 

I am a bit at a loss now. I guess I could go back to Debian Buster, where I had ZFS working (I broke it with a apt full-upgrade and then installed bullseye).

Should try switching to a 5.15.x kernel? How can I see which kernels have accompanying  headers?

 

Please help me get proper headers installed on my system. I am happy to provide any and all details from my system in addition to the ones specified above.

I am grateful in advance for your time, fellow armbians!

errors: No known data errors


Just to add that this is achieved in straightforward manner:
1. Download CLI image from download pages

2. Install headers via armbian-config

3. Installing packages: zfs-dkms zfsutils-linux

 

Done. Then dealing with ZFS.

I managed to get it working!

 

Using `armbian-config` I upgraded my kernel to `5.15.30-meson64`. Installing the headers via `armbian-config` didn't work, nor did it work via ``apt install.

What ended up working, was downloading the appropriate dtb and headers from https://imola.armbian.com/apt/pool/main/l/linux-5.15.30-meson64/  and installed them via `dpkg`. 

# dpkg -i linux-dtb-edge-meson64_22.05.0-trunk.0012_arm64.deb
# dpkg -i linux-headers-edge-meson64_22.05.0-trunk.0012_arm64.deb

 

Afterwards I installed zfs via the classic 

# apt install zfs-dkms zfsutils-linux

 

My current working configuration is listed below:

Welcome to Armbian 22.02.1  with Linux 5.15.30-meson64

 

zfs packages

  

$ apt list --installed | grep zfs

I see there are no more 5.15.30 files available, so I guess the link below should work now.
