Building ZFS on Raspberry Pi 3 running Rasbpian

Introduction

This is a tutorial for building and installing the latest release version (0.7.3 as of writing) of "ZFS on Linux" on a Raspberry Pi 3 running Raspbian Stretch. Specifically, we'll be building the dkms version of ZoL, which saves you the hassle of re-compiling the kernel modules after every kernel update. Even though ZoL added support for building dkms packages for debian in version 0.7.3, the build process on a Raspberry Pi 3 is not quite straight-forward. Hopefully, these instructions will make it easier.

Steps

  1. Install the build dependencies.
$ sudo apt-get update
$ sudo apt-get install build-essential autoconf libtool gawk alien fakeroot
$ sudo apt-get install dkms zlib1g-dev uuid-dev libattr1-dev libblkid-dev libselinux-dev libudev-dev libssl-dev parted lsscsi wget ksh

Patch for coreutils' b2sum that uses the sse implementation from BLAKE2/BLAKE2 for 20% faster checksumming.

Introduction

Coreutils comes with the binary b2sum which can be used as a faster (and more secure) replacement of sha1sum/sha256sum utilities. The coreutils package uses the reference BLAKE2 implementations from the official repository. These reference implementation, while being portable, are not as fast the optimised implementations available from the same repository. My patch uses the sse versions which are "optimized for speed on CPUs supporting SSE2, SSSE3, SSE4.1, AVX, or XOP".

On an Intel Core i5 (4th Gen, 2 cores) machine running macOS, the b2sum binary built with this patch was about 20% faster than the default coreutils binary.

Patching and building

  • Download the latest coreutils tarball. This patch was successfully tested on version 8.31.
  • Apply the patch patch -p1 < ../coreutils-blake2-sse.patch.
  • build using the standard instructions. (./configure && make)
