Running Nextcloud on Raspberry PI next steps

Introduction

As I discussed in my last post I did not have a well setup up location for my files to be stored. Sense then I have picked up a external Hard drive and a Raspberry Pi4 4GB to serve this purpose. In this I will be using ZFS mostly as I have been wanting to play around with ZFS on linux so this seemed like a good opportunity. For most people using Ext4 would be fine.

Installing ZFS

ZFS really wants you to be using a 64Bit Kernel. But while I attempted this on Arch, manjaro, ubuntu, and rasbian. I was not able to get any working. That with them all being in various stages of pre-stable drew me to building this on a 32bit Kernel. Once there is a stable 64bit kernel to move to I plan to do so. But I have also not experienced any issues with this setup despite the warnings. As always backups are highly recommended.

To get started add deb http://deb.debian.org/debian buster contrib to your /etc/apt/sources.list file and uncomment the deb-src line

deb http://raspbian.raspberrypi.org/raspbian/ buster main contrib non-free rpi
# Uncomment line below then 'apt-get update' to enable 'apt-get source'
deb-src http://raspbian.raspberrypi.org/raspbian/ buster main contrib non-free rpi
deb http://deb.debian.org/debian buster contrib

You will then need to add the pgp key for this source as well.

gpg --keyserver pgpkeys.mit.edu --recv-key 04EE7237B7D453EC
gpg -a --export 04EE7237B7D453EC | sudo apt-key add

The run sudo apt update

Now lets add some build tools that you will need

sudo apt -y install build-essential fakeroot devscripts autogen libelf-dev debian-keyring busybox initramfs-tools raspberrypi-kernel-headers

Now we will build in zfs-dkmas and spl-dkms

sudo apt -y build-dep zfs-dkms spl-dkms

Now for the main event, installing zfs. This will take quite a while. You will need to accept the building under 32 bit.

sudo apt install -y zfsutils-linux

Lastly you can reboot or add the kernel module.

sudo modprobe zfs

Now at last you will be able to create your zpool.

sudo zpool create -f nextcloud /dev/sda

Before moving on you can verify that it was created and working.

pi@raspberrypi:~ $ zpool list
NAME        SIZE  ALLOC   FREE  EXPANDSZ   FRAG    CAP  DEDUP  HEALTH  ALTROOT
nextcloud  1.81T   444K  1.81T         -     0%     0%  1.00x  ONLINE  -
pi@raspberrypi:~ $

Moving Nextcloud

Now its time to move my nextcloud install over to the new host, for the most part you can follow my previous post on setting up Nextcloud.

For that set up we will need to move over the data storage and the /var/www/html folders. As the Database was already on a different host we only need to point the new PI to point to the Database host.

Be sure to end up with www-data owning both the data dir and /var/www/html

I did need to re-authenticate the clients back to Nextcloud. But otherwise everything worked.

Conclusion

The Raspberry pie for is a much better device for Nextcloud with USB3 and the additional RAM. Monitoring the usage I am limited by the CPU. But I can live with that for now.
