Workload will be a mix of: OpenStack volume storage Docker/K8s volume storage Object storage Are there already empirical values which data throughput can be achieved with a ceph cluster built from RPi's 4B with 8GB if the data is stored on SATA or SSD devices via a USB3 <-> SATA controller. Most clusters do not benefit from seven or more Monitors. I ran this as a testing ground for about a And I then setup a ceph cluster, which just uses use the 'public' network, which is the same mesh as the proxmox cluster is using. I don't really have a lot of experience with this, I just read a ton and built a modest 5 node homelab cluster and 5 nodes seemed to be the the minimum count you want to be at. Introducing: Raspberry Pi 5! Setting up the Raspberry Pi cluster with Docker Swarm. 2 Click on one of the In this video we show you how to setup a qdevice for a Proxmox clusterA cluster needs at least 2 voting servers for activity and so you should have a minimum Got it figured out, this is so cool! :) I guess for pi-hole/unbound container, a daily replication is good enough. 1 K8's master, 4 nodes with 1tb ssd's attached (via usb port) and the x86 nuc with 2 Can anyone point me to good information on how to setup a Raspberry Pi Cluster for use as a Local NAS. M. Feb 24, 2022 by Mike Perez (thingee). Based upon RADOS, Ceph Storage Clusters consist of two types of daemons: a Ceph OSD Daemon (OSD) stores data as objects on a storage node; and a Ceph Monitor (MON) maintains a master copy of the cluster map. Highly available guests will switch their state to stopped when powered down via the Proxmox VE tooling. This can be NFS, SMB, Ceph, GlusterFS or Longhorn, to name a few. My setup is individual nodes, with 2. My goal is to build a cheap yet efficient NAS. #The elapsed time when a Ceph OSD Daemon hasn’t shown a heartbeat that the Ceph Storage Cluster considers it down. I configured Ceph’s replicated pools with 2 A Ceph cluster made from Raspberry Pi 3 boards. Each have 40Gb of Now that you have your Proxmox cluster and Ceph storage up and running, it’s time to create some virtual machines (VMs) and really see this setup in action! Create a VM: In Proxmox, go to the Create VM option and select an operating system (like Windows 10 or Ubuntu). And is it possible to use other applications such as: OpenHab, Docker, etc. Continuing from my last post “ceph on a Raspberry Pi” I thought of focusing on features and functionalities of Ceph. Raspberry Pi の OS としては、Cluster HAT が提供している Raspbian を使用します。基本的には Raspbian と同一ですが、Cluster HAT を制御するためのソフトウェア等がインストールされているので The Ceph File System, Ceph Object Storage and Ceph Block Devices read data from and write data to the Ceph Storage Cluster. I've been running both Ceph and Kubernetes on Debian for a couple of years now, and after the initial setup it's been rock-solid. I'm setting up a brand new 7. Sign up for the Rook Slack here. Ceph on ARM is an interesting idea in and of itself. 3x Proxmox/Ceph Node in HA (identical specs): Each Node will have: The boot drives will be installed on ZFS with a 2xNVMe in a mirror. Raspberry Pi 3: $ 35. Open comment sort options. The Turing Pi 2 offers some unique I'm not very exited to run this in containers either (Debian Buster does not include Podman). 1 cluster and I see that Ceph is back on the menu, so I'm a bit confused. It ensures consistency and reliability of data by utilizing RADOS (Reliable Autonomic Distributed Object Store) technology, which replicates data across multiple OSDs (Object Storage Devices) in the cluster. "The Pi-hole® is a DNS sinkhole that protects your devices from unwanted content" Please read the rules before posting, thanks Ceph now supports native interfaces, block devices, and object storage gateway interfaces too, so fsid is a bit of a misnomer. Yes, I've been out of the PM loop for a few years (if it's not broke, don't mess with it), but now that we're getting new hardware, I wanted to build a new cluster. So no Ceph 14 packages exist for Debian Stretch, or any other older because you can't run ceph on a low cost, low power machine like raspberry pi. Recommended methods . I might try using the Raspberry Pi's Ethernet if I Ceph is a software package that allows you to create a cluster of machines that act as a file store. Very useful! Later on, we will assign it its own LoadBalancer IP. I think I'll just use it this way instead of with ceph. In this Create a Ceph Storage Cluster. /related: I run 20TB of storage for my media server at home via 7 USB drives aggregated using LizardFS. io. 最近転職したりして忙しかったので久しぶりに書きます。 以前 hostPathで永続ボリュームを利用する手順 を書きましたが、 ちゃんとしたストレージが欲しいなと思ったのでRookのCephクラスターを構築してみることにしました。 I'm looking for tips about a Proxmox+Ceph installation. It has 3 MONs, 25 OSDs (4 to 6 OSDs per node). I’m not sure if it’ll be stable enough to actually test, but I’d like to find out and try to tune things if needed. Best. Available for free at home-assistant. Quite interested, I run a hyper-converged Ceph cluster at work, hosting VM's - wouldn't have thought it was usable on Pi's and USB drives. Which wouldn't surprise me at all - this hardware came from old retired servers, a couple of spare desktops we had that happened to be relatively strong, a bunch of disks that I found in a box that I think mostly came from a pack of spares for some of the little Hardware for my Raspberry Pi 4 K3s Kubernetes cluster. Just think, with a 1Gbps network, it takes approximately 3 hours to replicate 1TB of data. 99 Samsung 32 GB Micro-SD card: $ 15. not-a-bug. I'l like to get an extra network port purely for replication, I'm currently thinking Odroid H2 but they are currently out of This provides a more streamlined experience for administering your Ceph cluster by hiding Ceph components like placement groups and storage maps while still providing the options of advanced configurations. Asking for help, clarification, or responding to other answers. Ceph Storage Clusters have a few required settings, but most configuration settings have default values. cephadm is fully integrated with the orchestration API and fully supports the CLI and dashboard features that are used to manage cluster deployment. Now that you have a better understanding of what Ceph is and how it is used in Rook, you will continue by setting up your Ceph cluster. Redeploy ceph (from scratch) using ceph ansible on the stable-5. I was wondering if it is possible to setup my Raspberry Pi as a monitor for this Ceph Cluster? It’s time to run some tests on the Raspberry Pi Ceph cluster I built. For it we will use our usb keys like this: * ceph01 : 2 keys ( /dev/sda and /dev/sdb) * ceph02 : 2 keys ( /dev/sda and /dev/sdb) * ceph03 : 1 key ( /dev/sda) We will initialize our keys (still as ceph user): bash $ I started looking at Banana Pis back in 2014 when I was quoting up some options for a ceph cluster and ran into ambedded cy7 nodes. 99 Male USB A to USB B cable: $ 5. It had a very successful Kickstarter campaign, but production has been delayed due to parts shortages. These 2 pi3s are part of a docker swarm, along with the 4 Ubuntu VMs in the proxmox cluster. If you have additional clients that might access a Ceph FS or an installed RADOS GW, stop these as well. node: [6-in-1: Build a 6-node After running some benchmarks and tests on a Raspberry Pi 4 2gb model, I found that the Pi 4 could push a single external HDD or a single SSD but not both at once. Cephadm is a tool that can be used to install and manage a Ceph cluster. With High Availability on Bare Metal using Ceph and Orange Pi as inexpensive Single Board Computers. . I'm also looking to add some NVMe disks to the ceph cluster for caching to speed up r/w on the HDDs in ceph. You must pass the IP address of the Ceph cluster’s first host to the ceph bootstrap command, so you’ll need to know the IP address of that host. Feb 24, 2022 Mike Perez (thingee) Cephadm was introduced in the Octopus release to deploy and manage the full lifecycle of a Ceph cluster. data to be read from the hard disks and in turn prevents Ceph from correctly monitoring cluster health. To shut down the whole Proxmox VE + Ceph cluster, first stop all Ceph clients. Cluster Name: Ceph clusters have a cluster name, which is a simple string without spaces. The version of Ceph which shipped with the Raspberry Pi build is quite old - I think version 12 - while the current version shipped with Proxmox is version 15. Do I have the right idea here? Then once the ceph cluster is setup, the VMs and containers can then use it as memory for high availability, as in if a node goes down, the VM cuts over to another node and continues I’ll bite. Powered by a worldwide community of tinkerers and DIY enthusiasts. Low-level cluster operations consist of starting, stopping, and restarting a particular daemon within a cluster; changing the settings of a particular daemon or subsystem; and, adding a daemon to the cluster or removing a daemon from the cluster. But if you want it done for you, Rook is the way. Here are some new goals for you. I’m using 3x1tb nvme for vm and 3 HDD for bulkdata. Posted this to r/homelab yesterday, but forgot that at least some of the things I learned might be applicable here. With that done, one Ceph OSD (ceph-osd) per drive needs to be setup. The Pi seemed alright back then as well, but running 3. Config and Deploy. DEPRECATED: Please see my pi-cluster project for active development, specifically the ceph directory in that project. As these H3 based SBC's have one NIC each, I'm considering VLAN's to simulate 2 NIC's per each node's real NIC. I installed cephadm with sudo apt install -y cephadm and I'm trying to install a mon by running the sudo cephadm bootstrap --mon-ip 192. Seems like it might not break as easily. Saved searches Use saved searches to filter your results more quickly Now I have a 12 node cluster consisting of Pi Zeroes, Pi 2's , a Pi 3, several Pi 4's, and various singleboard x86_64 computers. Ceph Pi - Mount Up,* Vess Bakalov* → link. kubectl config set-context --current --namespace rook-ceph. None beats Ceph in data resiliency and for their prices you can almost get a third node for your cluster and I would not recommend deploying a cluster with 2. I decided earlier in the year to learn Ceph. cephadm can add a Ceph container to the cluster. 1 Login to Proxmox Web GUI. For example, if you do the default setting of having a node (physical server) as your failure domain, a single machine failure puts you into an unhealthy state with no way for the cluster How to remove/delete ceph from proxmox ve cluster; How to reinstall ceph on proxmox ve cluster; The Issue. 0 sowieso It's time to experiment with the new 6-node Raspberry Pi Mini ITX motherboard, the DeskPi Super6c!

Comments. #This setting must be set in both the [mon] and [osd] or [global] sections so that it is read by both monitor and OSD daemons. For more in-depth information about what Ceph fundamentally is and how it does what it does, read the architecture documentation ("Architecture"). Self managed ceph through cephadm is simple to setup, together with the ceph-csi for k8s. Provide details and share your research! But avoid . However, getting it to scale at home is far too costly both in terms of power usage and gear cost. Code Issues Pull requests Builds a cluster of servers using CEPH-CLUSTER-1 will be setup on ceph-mon01, ceph-mon02 and ceph-mon03 VMs. Cephadm was introduced in the Octopus release to deploy and manage the full lifecycle of a Ceph Setting up a Proxmox cluster with either Ceph or ZFS is a powerful way to manage virtualization and storage in a highly available and scalable environment. I run it on a raspberry pi 4 plugged into a UPS. Learn to build a Proxmox cluster for home lab use. cephadm makes it pretty simple to deploy across a bunch of hosts. 28 release, we introduced a new rook-ceph addon that allows users to easily setup, import, and manage Ceph deployments via rook. The biggest problem will be that single GE link for both the public and private CEPH interfaces. I added one R-Pi 4 to the cluster and it worked better than the quite dated but still capable Cephadm¶. 11. Then I connect each pi via Ethernet to a switch, and from that switch a fibre connection to a server that aggregates these 8 NASs into one volume that I can share over the network or use for emby or run docker containers off. This becomes problematic when trying to run a Ceph cluster on e. With the 1. Here's what my homelab looks like. This third node ensures the cluster can Hello, I want to build a 5-node minimum (maybe 7-13) Ceph cluster from *Pi SBC's, with 120 GB SATA SSD per node. But if I were doing what you're doing, I'd probably skip proxmox and just run CEPH and K8s on the bare metal. The recommendation for Ceph now are so vague, all the documentation has changed in recent years to talk about IOPS/core but is very vague about it. sudo snap install microceph sudo snap refresh --hold microceph sudo microceph cluster bootstrap sudo microceph disk add loop,4G,3 sudo ceph status You're done! You can remove everything cleanly with: sudo snap remove microceph To learn more about MicroCeph see the documentation: https://canonical-microceph. Create a three Ceph Node cluster so you can explore Ceph functionality. And the whole board is mini ITX, so it mounts in typical PC cases (traditional multi-Pi clusters can get messy!). sudo apt install -y ceph-common. osd_heartbeat_grace = 10 (default is 20) #How often an Ceph OSD Daemon pings its peers (in seconds). It seems that there are still no armhf Ceph binaries available. Things that generally can be run on an Rpi and SD-card. Atomic Pi Cluster Labgore Locked post. There are multiple ways to install Ceph. You can achieve the same with much less hardware, but this is what I have. My raspberries are running Ubuntu 21. 5" HDDs through the USB connection of the Pi seemed suspect. Als Speicher verwende ich drei 256GB Flash-SSD-Laufwerke. But not in a docker container. This post will be helpful if you already have a ceph cluster up and running. I do not recommend using a Raspberry Pi as your third Ceph monitor if it's anything like using It's worked fine for us, but shortly after we built the cluster, PM dropped Ceph. raspberry-pi ceph ceph-cluster storage-cluster ceph-pi Updated Jan 29, 2021; openSUSE / vagrant-ceph Star 18. figure out ceph public/cluster running on different networks - unclear its needed for this size of install Can’t remember any Gist on the Pi-KVM? It seems like a nice to have, and such an UniFi Power distribution is also very nice. Ceph config: Pool of NVMes for VMs => Proxmox will use this for their VMs (Mostly Been working this weekend building a raspberry pi ceph cluster and it seems that there are very few examples online for some of the new basic steps. USB drives will be OK, but you won't be able to scale more than 2 drives per Pi. Guess I first need to finish my migration before I start looking into a small rack myself. on the OSD's based on 4B-8GB RPi's, or does such a RPi no longer have When I try adding an NFS service to the cluster using the web dashboard, this message pops up in an overlay: Failed to apply: [Errno 2] No such file or directory: 'ganesha-rados-grace': 'ganesha-rados-grace' And in the logs: Failed to ap. I am running a 2-node Proxmox/Ceph hyper-converged setup however when one node is down, the shared Ceph storage is, understandably, down since it cannot keep quorum. ) Please note: this documentation is not perfect, it’s made for cephs “pacific” release, touches only those things that I have come across to and is mostly just a CEPH Storage Cluster on Raspberry Pi. I have no idea how ceph works. Pool Creation: I want to test both standard replicated pools, and Ceph’s newer erasure coded pools. Perfect to run on a Raspberry Pi or a local server. I tried a three node cluster using Raspberry Pi4s and it seems to be working well, one SSD per Pi. The two nic:s are in a bound each attached to separate 2. The Ceph Debian repositories do not include a full set of packages. Installation Sheet. The Accordind to Step 1 we consider that CEPH Complie for RBPI LAB Setup : 3 * RBPI With Ceph Compile. The Raspberry Pi 2 shown is used as a QDevice, as a cluster isn't stable with an even amount of Since Raspberry Pi is built on Arm, I decided to test this theory by installing OpenStack on a Raspberry Pi cluster. From there, you should have a functionnal cluster but without OSD (so cluster’s health at HEALTH_ERR): bash $ ceph -s Now, we need to add OSD to our cluster. conf and credentials. Small scale Ceph Replicated Storage, James Coyle → link. Building distributed Data Lake (Non-Production). How to A Ceph cluster made from Raspberry Pi 3 boards. Additionally, having such a low number of OSDs increases the likelihood of storage loss. Top. Addition of one more HDD and SSD connected to a Raspberry Pi CM4 with a very very jank Raspberry Pi IO Board PCIe x1 slot-> PCIe to SATA card setup. I wanted multiple hosts, because Ceph can greatly benefit from more hosts, and also because I wanted a bit of HA. 5" external HDDs (mostly SMR), so I actually get sligtly better performance than this The act of running the cephadm bootstrap command on the Ceph cluster’s first host creates the Ceph cluster’s first “monitor daemon”, and that monitor daemon needs an IP address. yml it runs for almost three minutes before hitting this fatal Quorum Node Dependency: With only two nodes, you need a third machine (which can be a low-power device, like a Raspberry Pi) to act as a quorum node. When Ceph added Erasure Coding, it meant I could build a more cost-effective Ceph cluster. My current solution is to use the box as a KVM hypervisor and run 3 VM nodes on it, each running an OSD. As far as the PI OSD, the memory should be fine, especially with a 8G Pi4. xPB cluster at a job (so, relatively small, in the Ceph world). 2 2280 slot (PCIe Gen 2 x1) * TF Card slot * 5V FAN Header * Micro USB 2.

CEPH is AWESOME once you get it to scale. However, Ceph at SMALL scale is a very, very tricky beast. The Pi's PCIe bus can put through 400 MB/sec (or 350-400 for writes), but when you attach it to the network and run through Samba or NFS, the throughput is down to 100-150 MB/sec (with 2. https Thanks for contributing an answer to Stack Overflow! Please be sure to answer the question. 10Gb is a cost that I don't need to spend just yet as the ceph Ceph on the other hand runs amazing. Don't hesitate to ask questions in our Slack channel. I've also tested clustering software like Ceph, which I also have in that Could this tiny Pi cluster be added to a much larger x86 cluster? Does it depend on one disk, per node? (Pi + disk, Pi + disk, Pi + disk)? Anything that runs ceph should work in the same cluster with other computers but if it is very I have set up a Raspberry Pi cluster before using 4 Raspberry Pi 3B+ units. These will mainly be VMs and containers. My question is can I connect a 2. 97 . 0 Network-Attached Storage or Distributed Storage System :6 x ARM NAS node or CEPH node; Note: Mini ITX Shelf Look also at services. Would it be better to LAG the two into 20 Gbps or use one dedicated network for Ceph with its own interface while another for Proxmox? There are more config options too as there are 2x2. I'm looking to deploy a new production ceph cluster, all ssd nvme. Ceph provides a unified storage service with object, block, and file interfaces from a single cluster built from commodity hardware components. We want to completely remove ceph from PVE or remove then reinstall it. I also have this GitHub repo with the Ansible automation I mention in the video.

I'm looking for Lenovo M90q due to less power consumption. A K3S cluster is composed of the following cluster nodes:. The MONs are deployed on OSD nodes, as are two of three MDS (we are currently outsourcing the MDS to Follow through this post to learn how to deploy Ceph storage cluster on Debian 12. I had a working file-server, so I didn’t need to build a full-scale cluster, but I did some tests on Raspberry Pi 3B+s to see if they’d allow for a usable cluster with one OSD per Pi. For a client node to connect a Ceph cluster, we need to ceph. Aside from running Ceph as my day job, I have a 9-node Ceph cluster on Rasberry Pi 4s at home that I've been running for a year now, and I'm slowly starting to move things away from ZFS to this cluster as my main storage. This repository contains examples and automation used in DeskPi Super6c-related videos on Jeff Geerling's YouTube channel . Like you say it depends how often critical data gets backed up. Probably going to start with ceph and experiment. - pabloromeo/clusterplex. I have checked the documentation and couple of different tutorials and after running ansible-playbook site. This Quick Start sets up a Ceph Storage Cluster using ceph-deploy on your admin node. The PI should be able to handle the monitor role for a small cluster ok. My biggest concern right now, could the Ceph storage be placed on a USB? The thing is, the stuff that I want to configure as HA will only be Pi-Hole, VPN server (1-2 connections at most) and perhaps a Teamspeak server. Hello r/Proxmox, I'm building a small two-node cluster (2 Dell R530s + mini PC for quorum) and the goal here is high availability.

Discover high availability, CEPH storage, and more. If you use Ceph, you can contribute to its development. This guide will walk you through the process of establishing a Proxmox cluster and integrating it with either Ceph or ZFS, focusing on the necessary steps, configurations, and best practices. cephadm can update Ceph containers. T. As a first exercise, create a Ceph Storage Cluster with one Ceph Monitor and three Ceph OSD Daemons. Now, see, that's really interesting to me because that really hammers home the idea that there is something wrong here. ) Please note: this documentation is not perfect, it’s made for cephs “pacific” release, touches only those things that I have come across to Mein Ceph-Cluster wird aus drei Raspberry Pi 5 bestehen, die über einen 1Gbit-Switch in einem privaten Netzwerk verbunden sein werden. To create a cluster login to the web gui of your MAIN cluster, node1 for us, and click on "Datacenter" (step 1 in screen), and there on "Cluster" (step 2 in screen). I'm also going to be reviewing a new cluster board, the DeskPi Super6c, later today. Corosync on the onboard 1g links, the main vm connection on a 10g which leaves me a 10g on each node for ceph or gluster dedicated network. Ceph is a scalable distributed storage system designed for cloud infrastructure and web-scale object storage. On a client node side, we first install ceph-common package. It also has a Raspberry Pi 2 that serves as a retro gaming console but for this post we'll be focusing on the Kubernetes cluster. Obwohl Solid-State-Laufwerke für eine bessere Leistung empfohlen werden, wird die Gesamtgeschwindigkeit durch die Nutzung von USB 3. you technically can ceph to work on a single node but it isn't recommended and involves lots of knob turning on cli. Install MicroCeph I can't say how a RPi will work in a Ceph cluster, but if it helps I can give you some numbers from a production cluster. Currently the default ones are not all built as multi-arch yet and therefore don’t all work on arm64. My MON-IDs are proxmox196, proxmox197 and proxmox198, so replace these with yours. Deploy or manage a Ceph cluster Has anyone tried creating a Ceph cluster with a single OSD per SBC. For Ceph require at least 2 nodes for 2-node cluster Configuration with 1 Quorum Votes Device (Qdevice) this device use for Quorum Votes only no need more storage, cpu and memory, you can put the qdevice on a vm or pi device. Covers IP setup, installation, and node configuration. It’s also a low cost way to get into Ceph, which may or may not be the future of storage At the end of the playbook, there should be an instance of Drupal running on the cluster. Has anyone of you been able to get Ceph Luminous running on The Pi 3? Your advice would be appreciated. A. Ceph. The UAS driver in the Linux kernel has ATA command pass through disabled for all Seagate USB drives due to firmware bugs.

It you set up a Ceph storage cluster using some Raspberry Pi computers, I would be interested hearing how it went. The installation guide ("Installing Ceph") explains how you can deploy a Ceph cluster. We had 2 of the pis running a tomography reconstruction using the rest as a ceph storage cluster, and the lights showed traffic. Thus, requires you to have 7 Pis for 56 TB. Goal is for the VMs to run on any node without large delays in moving them across (so a cluster fs of some sort). and just barely work on the Pi Like cluster filesystems running pcie 8x Switch to the raspbernetes images instead of the default ones. Here is a list of some of the things that cephadm can do:. If you haven’t completed your Preflight Checklist, do that first. The other went NFS. some CEPH + ROOK and ended with Longhorn. 99 Microcenter USB 2. btw, 10GE is the minimum requirement for a non-hobby ceph cluster Cluster case with fans. Since there is no official arm support I am using the raspbernetes images like the guide rook on arm , I hope I am in the right place to ask for guidance. I was able to setup the osd with the lvm2 volume. What it lacks in local file system anything is made up for by the speed and ease of rebuilding nodes for the cluster. More on Raspberry Pi. However, those Yes, if you have a CEPH cluster, I would use that directly to allocate PVs. Copy link I love Ceph and have supported a 1. I could use say 8 raspberry pis with sata hats for all the drives, mounting 4 drives per pi. So I built a small raspberry pi cluster (1 mon and 2 osds + 1 raspberry where I run things from) to get into cluster things and now I'm trying to install ceph via ceph-ansible. A Ceph Storage Cluster may contain thousands of storage Separate to the proxmox cluster, I have 2 pi 3s which run Ubuntu also. ceph-mgr-cephadm, but is Explore my home lab’s Proxmox cluster hardware featuring Lenovo Thinkcentre and Raspberry Pi. Share Sort by: Best. You can assign the VM to use the Ceph storage, which means your virtual I have spent the last few days trying to isntall a ceph cluster on my little raspberry pi 3 B+ home lab cluster without much success. This also prevents S. readthedocs-hosted. However, will Ceph put any extra strain on the USB drive that might My use case is using the Ceph cluster as general purpose storage; I've got my VM disks on RBD volumes using a mirrored pool, and media data and my application data stored on a CephFS that's backed by an EC2+1 pool. 5” drive via SATA to USB for each Raspberry Pi, cluster them and create one hard drive to combine the space as one drive? In my opinion, the current state of the art is Ceph. Our cluster will have a lightweight distribution of both Kubernetes and Ceph, a unified storage service with block, file, and object interfaces. So, I got wondering: maybe I could quit fighting with Kubernetes and find and easier way to run my Raspberry Pi 4 cluster. This provides 66% cluster availability upon a physical node failure and 97% uptime upon an OSD failure. You are going to want at least 5 servers, each with 2x10GE (40GE preferred) interfaces, 1 core per OSD (Ryzen is great here), 1-2GB RAM per OSD, another 2 cores and 2GB RAM for running the monitors as VMs on the same server, and a The home lab I am building is shown in the following picture. (Three B+ models and one older non-plus board. True, the Pi 4 with 8GB RAM would allow for 8 TB max recommended storage per node.
