In this tutorial, we will build a NAS using a variety of old hardware and the open-source storage solution Ceph. Follow along with the video and the steps below.

[00:00 - 00:02] I'm building a NAS with all of this: A bunch of junk and spare parts I found in my storage closet. A couple old laptops, a Zima board, a Ugreen NAS, a TerraMaster NAS, an old Dell server, a pile of random servers and hard drives, and a few Raspberry Pi's.

[00:21 - 00:24] With an open-source magic technology called Ceph. It's software-defined storage and it's crazy.

• CPU: ARM or x86
• RAM: Minimum 4GB
• Storage: External or internal hard drives/SSDs (USB flash drives are not recommended)
• Network Switch: At least 1 Gigabit for lab, higher for production

• OS: Ubuntu 22.04 (Use 20.04 for Raspberry Pi with Reef 18.2.2)
• Additional Tools: SSH, Docker, LVM2

1. Install Ubuntu 22.04 on all hosts.

2. Install SSH server:

   sudo apt install openssh-server

3. Set static IP address in netplan configuration:

   cd /etc/netplan
   sudo nano your-config.yaml

4. Update and upgrade system:

   sudo apt update
   sudo apt upgrade -y

5. Set a password for the root user:

   sudo passwd root

6. Enable SSH login for the root user:

   sudo nano /etc/ssh/sshd_config
   # Un-comment and set "PermitRootLogin yes"
   sudo systemctl restart ssh

1. Identify storage devices:

   lsblk

2. Wipe storage devices:

   sudo sgdisk --zap-all /dev/sdX
   sudo wipefs --all /dev/sdX

1. Install Docker:

   curl -fsSL https://get.docker.com -o get-docker.sh
   sudo sh get-docker.sh
   
   ## refer to this link: https://docs.docker.com/engine/install/ubuntu/

2. Install LVM2:

   sudo apt install lvm2

3. Verify time synchronization:

   timedatectl status

1. Set environment variable:

   export CEPH_RELEASE=18.2.2

2. Download and install CephADM:

   curl -o cephadm https://raw.githubusercontent.com/ceph/ceph/${CEPH_RELEASE}/src/cephadm/cephadm
   chmod +x cephadm
   sudo ./cephadm add-repo --release ${CEPH_RELEASE}
   sudo ./cephadm install

3. Bootstrap Ceph:

   sudo cephadm bootstrap --mon-ip <Manager-IP>

1. Copy SSH keys to hosts:

   ssh-copy-id root@<host-ip>

2. Add hosts to the Ceph cluster:

   sudo ceph orch host add <host-name> <host-ip>

1. List available devices:

   ceph orch device ls

2. Add all available devices as OSDs:

   ceph orch apply osd --all-available-devices

1. Create Ceph file system:

   ceph fs volume create cephfs

2. Mount CephFS on Linux:

   mkdir -p /mnt/ceph
   mount -t ceph <mon-ip>:6789:/ /mnt/ceph

3. Install and configure Samba for Windows access:

   sudo apt install samba

[41:00 - End] Enjoy your new Ceph-powered FrankeNASS!
