“But where do I find further information about the #Proxmox QDevice in my cluster?” - In #PegaProx!

The next release will be big and comes with an improved new corporate layout and many new features that make your life easier! Simple things like information about the QDevice or link speed of PVE nodes are now directly shown from the PegaProx UI. I don’t want to spoiler too much, so stay tuned for the next big update of PegaProx!

A Catalogue for the Library: Graylog Dashboards on the Proxmox Cluster

Logs are a lot like the universe: vast, mostly empty, and every so often something in them is on fire.

Since the Graylog part, a month of log lines from the clust

RE: podcasts.social/@behindtheconsole/…

My Proxmox lab’s logs were well kept and never read. Now Graylog reads them: three Data Nodes that never move, one server that moves when it has to, and every remote address in one field, so one search follows one visitor everywhere.

Seven failure tests found a firewall that had never been on. A Data Node rebuild went from 39 minutes to 9.

A Reader for the Archive: Graylog on a Three-Node Proxmox Cluster

Every node already writes home. Somebody has to read the letters.

Since the first part, every node of my three-node Proxmox lab sends its syslog to a log host outside the cluster. Tha

Three Small Computers, One Big Promise

In the beginning there was one server, and it was fine, right up until the moment it was not.

What follows is the logical next step for anyone who has ever stared at a single server and wondered what would happen if it simply stopped. I built a three-node

Proxmox VE HA Lab Cluster

In the beginning there was one server, and it was fine, right up until the moment it was not. This document describes the design, build, hardening and day-to-day care of a three-node Proxmox VE cluster whose sole purpose in life is to be broken on purpose, so that high availability (HA) can be observed in its natural habitat. The nodes are

refurbished is good enough

To build my 3 node Proxmox Cluster I ordered three refurbished Lenovo ThinkCentre M720q.

Planning #proxmox cluster

Keep everything inside three small boxes. No shared storage server, no NAS, nothing else that
could fall over while nobody is looking.*

*) Things that fall over always wait until nobody is looking. This is one of the fundamental laws of the universe.

Thin LVM with shared block storage in #Proxmox? YES!

At our #Proxday, several people came in touch w/ me & said that LVM thin-provisioned with iSCSI, FC or NVMeoF would be a dream. Let me make it become real!

PS: My mate @formorer@rollenspiel.social is also working on something huge! Guess, we should make a special event about storage plugins for Proxmox VE - maybe within the next virtualization gathering at @credativde@mastodon.social or maybe as a special edition. Let’s see, stay tuned!
