Raspberry Pi RAID

#### Raspberry Pi RAID Konfiguration ####

## Update Sources ##
sudo apt-get update

## Install RAID Software mdadm ##
sudo apt-get install mdadm

## Reboot Pi ##
sudo reboot

## Check disks ##
lsblk

## Remove all data & partitions from disks ##
sudo parted /dev/sda "rm 1"
sudo parted /dev/sdb "rm 1"

## Check if no partitions are on disks ##
lsblk

## Create MSDOS Table if disk is < 2TB ##
sudo parted /dev/sda "mklabel msdos"
sudo parted /dev/sdb "mklabel msdos"

## Create GPT Table if disk is > 2TB ##
sudo parted /dev/sda "mklabel gpt"
sudo parted /dev/sdb "mklabel gpt"

## Create partition on each disk ##
sudo parted /dev/sda "mkpart primary ext4 1M -1"
sudo parted /dev/sdb "mkpart primary ext4 1M -1"

## Activate RAID for each partition ##
sudo parted /dev/sda "set 1 raid on"
sudo parted /dev/sdb "set 1 raid on"


## Check status ##
sudo parted -s /dev/sda print
sudo parted -s /dev/sdb print

## Create RAID Level 0 ##
sudo mdadm --create /dev/md0 --level=0 --raid-devices=2 /dev/sda1 /dev/sdb1

## Create RAID Level 1 ##
sudo mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sda1 /dev/sdb1

## Check staus ##
lsblk

## Create Datasystem on RAID-System to be able to put files on it ##
sudo mkfs -t ext4 /dev/md0

## Check prograss ##
cat /proc/mdstat
sudo mdadm --detail /dev/md0


## Create Mount Directory ##
sudo mkdir /media/raid

## Mount RAID ##
sudo mount /dev/md0 /media/raid

## Configure autostrat & mount at boot ##
sudo nano /etc/fstab/
add: /dev/md0 /media/raid ext4 4,nofail 0 0

sudo crontab -e
add: @reboot sleep 5; sudo mount /dev/md0 /media/raid

### Use RAID as Nextcloud data directory ###

sudo su

mkdir /media/raid/nextcloud/
chown -R www-data:www-data /media/raid/nextcloud/

## open current data directory ##
cd PATH/TO/DATA/
mv data /media/raid/nextcloud

## Configure Nextcloud data directory ##
nano /var/www/nextcloud/config/config.php

edit this line: 'datadirectory' => '/media/raid/nextcloud/data/',

## restart webserver ##
service apache2 restart
