Nein, ich nicht - ich habe solche Geräte nicht ;-) Netztrennung. "Komische" Dienste und Corosync+Adminzugang zu den PVE würde ich immer trennen.

gurubert reacted to Johannes S's post in the thread Solo business owner, can I use proxmox as an alternative to Windows 365? with Like.
I disagree. For a non-technical user ( which OP clearly is ) a managed service ( be it oiffice365 or nextcloud/onlyoffice if you don't want to depend on Microsoft) is the easiest and most frictionless variant. To save on 41 bucks by running...

Hi @galffing , I hope you don't mind me saying this, but based on the questions you've asked, it seems like W365 would be the best fit for your business needs. Blockbridge : Ultra low latency all-NVME shared storage for Proxmox -...

Anything in the kernel logs about the interfaces maybe losing the connection? That could trigger the switch to the other interface. If you do a multi-switch setup, the best approach would be to configure the two switches in an MLAG configuration...

gurubert reacted to Francois Baillargeon's post in the thread Proxmox + Ceph across 2 datacenters with Like.
Adding to @SteveITS bandwith is indeed important, if you can get to 25 or even 100gigs between sites.. You have to keep in mind that say, in RF4, each written block gets written to 4 places for safecopying, that's a lot
-
What is the speed and latency between the two locations? Hopefully 10 Gbit or higher? I could see this being very slow in several cases since at least 1/3 of all I/O is copied to the other data center. 4 nodes is more than 3 but you may want...

gurubert reacted to Francois Baillargeon's post in the thread Proxmox + Ceph across 2 datacenters with Like.
I agree with the others that this is a setup with many caveats and has high disk consumption (due to the requirement of having rf4) Also this sounds like Corosync will be over shared media , so make sure your QoS is tight accordingly

Hey @abhijithiaaxin, welcome to the forum. Whether it is a single-DC deployment or a split-DC deployment, you generally want an odd number of nodes in your cluster. But, as others have pointed out, a split-DC installation requires three...
-
As @gurubert already mentioned, you will need one node in a 3rd location. Our Stretch Cluster guide has more details on how to get it up and running: https://pve.proxmox.com/wiki/Stretch_Cluster You will have to span up a layer2 network between...

gurubert reacted to t.lamprecht's post in the thread Proxmox Virtual Environment now available for 64-bit ARM (arm64)! with Like.
We are excited to announce the first release of Proxmox Virtual Environment with official support for a second CPU architecture: 64-bit ARM (arm64/aarch64). Until now, Proxmox VE was available for x86-64 (amd64) only. Proxmox VE 9.2 for arm64...

gurubert replied to the thread Proxmox + Ceph across 2 datacenters.Basically you need three locations for automatic HA. Otherwise you will always have issues with split brain situations. Addendum: If there is no common layer 2 network available for the VM traffic you cannot migrate a VM from one location to the...

Ich muss zugeben, dass ich hier mal kurz laut lachen musste. Chapeau für den passenden Vergleich. :-) Etwas ersnthafter: Natürlich ist die Anfrage in der Kombination unsinnig. Allerdings haben wir ja alle mal klein angefangen und viele...

Moin Was hat Proxmox mit einem Laptop für's Studium zu tun? :D Bei einem Laptop für's Studium wird es ja vermutlich in erster Linie darum gehen mit irgendeiner Office-Software irgendetwas erstellen zu können und das hat erst einmal herzlich...

Nimm besser ein Linux mit Desktop deiner Wahl und darauf dann VirtualBox oder virt-manager. 8GB nur für Studiumskram und kleine VMs ist ok, mit Windows-VMs eher nicht. ProxmoxVE hat standardmäßig keine GUI und weder DHCP- noch WLAN aktiviert...

It should be "nice" :)

gurubert reacted to meyergru's post in the thread [Community project] Proximo — an open-source, least-privilege MCP/API layer for managing PVE with an AI agent (feedback wanted) with Like.
You either cannot or will not understand the essential point here. Let's be clear: You built an MCP tool that allows an AI to manipulate core infrastructure. That in itself is a massive risk if you don't trust the AI. But even if you strictly...

gurubert reacted to robertlukan's post in the thread Migration from VMware vSAN to Proxmox CEPH with Like.
I would say it is possible if you are willing to take quite some risk while migrating VMs as there is no room for redundancy. Ceph does not like 2 monitors, so you will need to trick it. It is possible, but maybe not the best approach. Proxmox...

gurubert replied to the thread Migration from VMware vSAN to Proxmox CEPH.This will only work if the current VM workload only needs less than half of the available hardware resources.
