I just did this yesterday, using the Proxmox GUI. YMMV I suppose, but since I added the new drives first, what I did was: Out the OSD. This will start to rebalance in the background but all PGs remain blue or green. (blue I believe was due to... -
Well like often the answer is: It depends :) Or to be more precise what workload are you planning to run, which downtimes/riscs you can live with and what tradeoffs you are willing to make. First: ZFS and Ceph both want to mange the discs...

Like.
Guide on how to use the CLI-based QEMU manager in Proxmox, which is named 'qm'. The guide covers everything you always wanted to know and were afraid to ask about managing QEMU/KVM and has a lot of tips you will not find anywhere else. As far as... -
UdoB reacted to Johannes S's post in the thread Migration possible from PVE 7.4 to latest PVE 8? with Like.
No, as written by Thomas Lamprecht on the first post of this thread: You could try the pct remote-migrate or qm remote-migrate cli tools but I'm not sure whether they were already available for PVE7 and whether a migration from PVE7 to PVE8...

UdoB replied to the thread Esxi migration to proxmox.I've tried to use Ceph in a small Homelab, with hardware three classes below yours (Mini PC and slow network). I've learned that there are some pitfalls and I would work hard to start with five instead of the absolute minimum if three nodes...

UdoB reacted to Johannes S's post in the thread PBS on desktop pc with SSD or in VM on PVE or not at all? with Like.
Good question, indeed ssh is needed for communication and migration between cluster nodes (according to https://pve.proxmox.com/wiki/Cluster_Manager#_role_of_ssh_in_proxmox_ve_clusters ) but the documentation says nothing about qdevice. The...

UdoB reacted to Johannes S's post in the thread PBS on desktop pc with SSD or in VM on PVE or not at all? with Like.
One thing to consider for using the PBS as qdevice: If you add a host as qdevice every node of the cluster can login as root on the qdevice (and thus the PBS) without additional authentification. This is something you usually don't want on your...

UdoB replied to the thread PBS on desktop pc with SSD or in VM on PVE or not at all?.I'm not using one, but I have a question: that seems plausible during setup, but during operation? Is ssh-access actually used for a QDev "doing its thing"? If not one could disable it after installation... My (possibly wrong) understanding was...

UdoB reacted to JeanL's post in the thread PBS testimonial (hardware requirements are a joke) with Like.
Hi, For deduplication YMMV, for example, if I look at our PBS, it's pretty good with more than 90% of Linux VMs (more than 60% of these Linux machines are Debian), and retention from 14 to 365 days. We have critical VMs which backups run every...

UdoB reacted to RedLemon's post in the thread [TUTORIAL] Advanced Wake-On-LAN daemon for Proxmox (VM + LXC, auto-MAC mapping, cooldown, logging, systemd-ready) with Like.
Hello everyone, I recently needed a reliable solution to start VMs and LXC containers on my Proxmox node using Wake-On-LAN packets, without relying on external systems (Home Assistant, scripts on another machine, API calls, etc.). I found the...

UdoB replied to the thread PBS testimonial (hardware requirements are a joke).Obviously that depends on the modified data per interval and the "prune"-settings. And it needs a number of backups present to work at all :-) Both my dayjobs cluster and my homelab show around 30 - with basically "everything daily". If I would...

UdoB reacted to IsThisThingOn's post in the thread PBS testimonial (hardware requirements are a joke) with Like.
Clickbait headline, but I think it is true :) Maybe others can chime in with their setups and why they need beefy hardware. Here is my PBS testimonial. Reading the documentation I was a little bit scared. Especially the storage part seemed...
