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...

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...

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...

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...

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...

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...

How to re-produce: 1) Set replication of a KVM vm between two nodes and let it sync 2) Remove one of the nodes: pvecm delnode nameofnode (then permanently shutdown as per instructions). 3) On remaining node replication task remains and is un-removable, task error: Replication Log 2017-09-20...
