Fail to build zfs dkms module

[grisu48]

Hey there,

 

I'm running Armbian 23.8.1 Bookworm with Linux 5.10.160-legacy-rk35xx on a Rock 5B and am trying to get zfs via dkms to work, but it won't compile.

 

...
configure: error:  
       *** None of the expected "file_fallocate" interfaces were detected.
       *** This may be because your kernel version is newer than what is
       *** supported, or you are using a patched custom kernel with
       *** incompatible modifications.
       ***
       *** ZFS Version: zfs-2.1.11-1
       *** Compatible Kernels: 3.10 - 6.2

Error! Bad return status for module build on kernel: 5.10.160-legacy-rk35xx (aarch64)

 

I'm attaching the full build log, perhaps someone has a clue?

dkms-zfs.txt make.log

FYI. Not Armbian problem.

Thanks! I will follow up there.

https://github.com/openzfs/zfs/issues/15081#issuecomment-1647094056 doesn't sound promising though:

 

See here radxa/kernel#54 (comment)

Rockchip BSP kernel is forked from Android Common Kernel, don't think ZFS would support the Android kernel any time soon.

https://github.com/radxa/kernel/issues/54#issuecomment-1501031920 points out a possibility by patching the zfs sources.

 

I am not sure if I want to go down that path.
