Resize a Hard Disk for a Virtual Machine

Our Virtual Machines are provisioned using Vagrant from a Linux base box to run using VirutalBox. If the Hard Disk space runs out and you cannot remove files to free-up space, you can resize the Hard Disk using some VirtualBox and Linux commands.

Some assumptions

The following steps assume you've got a set-up like mine, where:

The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)

This creates an archive that does the following:

rsync (Everyone seems to like -z, but it is much slower for me)

• a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
• H: preserves hard-links
• A: preserves ACLs

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
