Looks like the 8gb Pi 4 is now available to order: https://www.raspberrypi.org/blog/8gb-raspberry-pi-4-on-sale-now-at-75/ With 8gb of ram there will no doubt be increased interest in running containers and even hypervisors on the Pi 4.

VMware has already shown a demo of ESXI running on Raspberry Pi https://youtu.be/UwOhiq5YOJ0 https://youtu.be/d6bN4ayBFWk

Imagine: A cluster of Raspberry Pi 4's each with 4gb of RAM and full Gigabit capable of running LXC containers with HA failover and Ceph storage. Use of ZRAM could allow around 2.5 to 3gb of actual container memory usage per Raspberry Pi 4 node, limiting Ceph bandwidth to say 800mbps could...

t.lamprecht, thank you for the brilliant explanation. Two nodes at each "site" plus an external quorum member sound like the way to go.

I have a 3 node Proxmox cluster and I'm wanting to add a fourth node in a different location in the building with it's own UPS that can act as a "Node of last resort". Eg, the main server rack fails (UPS, switch or extended power outage) but this node will have its own UPS that can run for a...

Hey folks, Just wanted to report that I've recently been testing Club-3D 2.5Gbps USB Ethernet Adapters with Proxmox. Happy to report that they work out of the box with no additional software installation. dmesg | grep 'enxa0cec8c94d63' 2500 mbit/s downlink 2500 mbit/s uplink These are a...

Bingo, I think I've solved it when I saw this: https://forum.proxmox.com/threads/host-unreachable-with-firewall.49273/#post-230218 "If you remove the source address it should be any (0.0.0.0/0). If you specify one it is assumed to be /32." In my ceph config: cluster network = 192.168.7.0/24...

With zero changes for the last week, I just logged in today to find Ceph broken (couldn't communicate with other nodes), I disabled the firewall and it all started working again. What is best practice RE Proxmox hosts and ceph firewall? I even tried complete allow all access via firewall and...

You gave me a tip (thank you!), firewalls were enabled on all nodes except for one. I disabled and re-enabled the firewall on each node, now for some reason it works with the firewall enabled using the Ceph macro.

Hey folks, I'm seeing an issue when the cluster firewall is enabled with the Ceph Macro (both in and out). 1) Enable firewall 2) Immediately ceph fills with mons going down and keeps going until the firewall is disabled. I've even tried setting the default input and output policies to ACCEPT...

The OSD was intially created using the GUI, I then followed the steps in the above post. It's probably possible to fix the issue by just running the last few steps although I didn't test it.

Hey folks, Reporting a solution for a problem I saw just recently with a new OSD not showing up in Proxmox web GUI or "ceph osd tree". To resolve I erased the drive (sda): dd if=/dev/zero of=/dev/sda bs=1M count=1024 conv=fdatasync Created a new OSD: pveceph createosd /dev/sda Get the...

I've asked previously, can we please have a home / hobbyist license for up to 5 nodes at a reasonable price. Similar concept to Royal TS personal bundle "Royal TS/X + Royal Server Personal License".

Hey folks, I've got a small 3 node proxmox cluster, some nodes have different numbers of cpu cores. This stops vm's assigned more vcpus than available on another node from failing over to the less powerful node. Can we please have an option in the GUI to if necessary shutdown a vm that needs...

Yea but there is still the no subscription pop-up everytime I login or click on a NUC.

I'd like to support the project but it's not economical considering I only use it for my home network. I've got a few NUC's, one runs Plex, another Domoticz Home Automation software and then a Ubuntu machine running VNC. There need's to be a practical subscription model for this type of setup...

This is a guide for creating and running ClearOS in a Proxmox LXC container: 1) Install ClearOS 7.4 in a KVM virtual machine using Proxmox 2) After installation, go into the VM's terminal using Proxmox web interface and install rsync with: yum install rsync Run these commands to enable SSH...

+1 for this option, would be ideal to automatically migrate VM's when initiating a manual node reboot.

Thanks for providing the steps you used to allow CIFS mounts in LXC containers, it's much appreciated! :)

Nice catch RE swappiness, I copy this script between machines frequently and pulled this from one of my Raspberry Pi's. A value of about 10 is more suitable for Proxmox I think (if you want the kernel not to use swap unless absolutely nessesary, then value should be 1). I've changed the script...
