cluster

(This is a non-production environment) After a recent power cut, I ended up with a split cluster which consisted of three nodes (may switch came up last... After repeated attempts to reboot them all, one at a time, two...I gave up. Grantted, I should have asked for help at this point... One...

Hello, I am doing some test about clustering two physical nodes along with a qDevice VM which role is to complete the quorum for a healthy cluster. The storage used for the VMs is an iSCSI share based on a 2022 Windows Server. The storage is accessible for both nodes. The first test I...

Hi, guys i just finished my post about the "How to Configure Fibre Channel SAN Storage with Multipath and High Availability on Proxmox VE 9" , if you have some advices /tips are welcomed...

Hello everyone, I am reaching out to you because we are trying to migrate from VMware VSAN to Proxmox. First, let me give you a quick overview of our current situation. We have a cluster of three nodes (vxRail) with 10 HDDs and two SSDs (vSan in cache tiering) and a 10G network. I have done...

Hey all. I have a configuration question for my home lab setup. Currently I have a 12-bay Dell PowerEdge r540 with 12 x 3.5" drive bays. I would like to maximize my storage on that server and use it as a shared ZFS pool across the network. The servers will have their own network away from...

Dear, I am facing to a choice to share the existing ceph storage from proxmox cluster to K3S cluster. Is it best practice to do that or need to SoC and each cluster has his own storage ? If proxmox manage the ceph storage is it a good governance ? Some clarifications are welcome. Best Regards,

I'm getting vm migration error during node reboot due to kernel update on a 3 node hyperconverged cluster with ceph installed. Error is here: Cleanup after stopping VM failed - org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not...

NTP doesn't sync correctly with only one of my computers in my cluster, and I was wondering how I could change the NTP time or maybe sync it correctly? Here is the status of it, its about 5 hours off. Yes, my system is called butt. ● chrony.service - chrony, an NTP client/server Loaded...

I've encountered a synchronization and availability issue when using NFS network storage within a Proxmox VE cluster. - Environment: Proxmox VE Cluster with 2 nodes (node 01, node 02). - Storage: Synology NAS shared via NFS. - Configuration: The connection to the NAS is made through a public IP...

Hi everyone, I have a Proxmox cluster with 2 nodes. Node 2 has a 12TB disk (currently empty) that I’d like to use as shared storage between both nodes. My goal is: Store VMs on this shared disk Be able to migrate VMs between nodes without copying the disks Be able to take snapshots of those...

Greetings. I wanted to suggest a feature; having one unified page to control multiple nodes without clustering them. It should behave just like when you add a clustered node, show up in the tree view like it does but have no quorum requirement(s).

Hallo, habe Probleme mit dem ZFS und komme nicht weiter. Ich nehme an das ich bei der Einrichtung der Laufwerke ein Fehler gemacht habe und hoffe der ist noch zu korrigieren. Habe 2 Knoten wie folgt eingerichtet: Irgendetwas habe ich wohl falsch gemacht. Die Replizierung läuft durch. Aber...

Hello Everyone I seem to struggle when it comes to the Ceph full-mesh cluster created. I made one using a bond on each node using the fiber NIC's two interfaces of 25Gbps fiber card. Later I made an additional corosync link, not sure if this picks up if the other is down. I have created a pool...

Would love to know more about COLO Lockstep Fault Tolerance as it's already been in development for years. Curious to know what are the challenges holding up the implementation?

1. Can you take 3 servers with 4 port networking and connect them in this fashion: A - B A - C B - C with 3 cables and have redundant networking? (literal redundant would require 6 cables and eat all ports I think) 2. Are there three nets in the end? (and then possibly connect them all together...

I have a 2 node proxmox cluster running version 8.4.14, with a Raspberry Pi acting a as a qdevice for quorum. Kernel 6.8.12-15-pve I've taken pve-2 out of the datacentre to do some hardware work on it, and pve-1 had all the VMs running on it prior to powering it off. I then noticed my...

Hallo Ihr Lieben, ich habe eine generelle Frage. Ich bin dabei meine ersten VM und LXC zu erstellen. Ich weiß auch wie die USB DDevice zu den VM oder LXC durchgereicht werden. Nun zu meiner Frage: "Wenn ich ein Cluster Verbund aufbaue, wie kann ich dann die USB Device auch bei den anderen Nodes...

Hello, I just updated my cluster to proxmox 9, and most nodes went well, except 2 of them that ended up in a very weird state. Those 2 nodes hung at "Setting up pve-cluster". And I have noticed that /etc/pve was locked (causing any process that tried to access it to lock in a "D" state) The...

i had a cluster with 4 nodes and a qdevice so 5 votes. I wanted to remove 1 node and the qdevice because I experienced split brain. after trying to remove one node it sees only itself in a cluster but the real cluster has it still listed as offline so I can't use pvecm delnode to remove it...

Hi all, I am looking for some guidance on the clean removal of a node from Proxmox cluster. What I did so far: - Created cluster named 'Test-PVE' - Added three nodes (proxmoxVE01-03) to the cluster - Verified cluster manager status and nodes via 'pvecm status' and 'pvecm nodes' -> all three...
