cluster

Hallo zusammen, ich hocke momentan an einem Konzept für ein Disaster Recovery zwischen zwei Standorten. Mich würde mal interessieren, ob meine Idee so umgesetzt werden kann, und was eure Meinung dazu ist. Folgendes Szenario: Standort A und Standort B. Beide Cluster sind wie folgt aufgebaut...

Hi everyone, I'm troubleshooting a two-node Proxmox cluster with a qdevice and have run out of ideas. Environment Proxmox VE 9.2.5 corosync 3.1.10-pve3 2 cluster nodes: node-a (site A) node-b (site B) qdevice/qnetd on a third device (raspberry pi in same network as node-a) Sites connected...

Hallo, Ich habe Proxmox VE 9.1.1 auf meinem mini PC laufen. Auf dem Gerät läuft ein Container der jeden Tag um 23 uhr ein Backup fahren soll. Das ist aber die letzten Tage nicht passiert also wollte ich das ganze mal Manuel anstoßen um zu prüfen da los ist. Dabei hab ich folgende Fehlermeldung...

Hi, I'm running a 3-node PVE cluster (all on version 9.1.1, except one node on 9.1.4) and I'm facing an issue where the hookscript for vzdump is not being triggered at all on one specific node, while the exact same setup works perfectly on the other two. Cluster setup: Node A (proxmox)...

Hallo Forum! Ist es empfehlenwert beide nebeineinander zu betreiben? Wenn ja, was muss man in einem solchen Fall beachten? Ich habe aktuell in einem V9 Cluster mit raspi quorum (der Raspi ist kein echter node) Problem mit der VM Replikation die sehr lange braucht (ok, ist die erstreplikation)...

Hey guys, i need to re-install an existing node of my ha cluster because of a storage re-design. Now the cluster is a 7.2.11, but i can only find a 7.2.3 iso. Would it be safe for a newly installed 7.2.3 machine to join the 7.2.11 cluster? An update to 7.4 is not an option. This has been tried...

Hi! I have a 4 node proxmox cluster, configured as follows: * All nodes are connected to a switch, in the 172.16.0.0/24 IP range with one of their eth interfaces. * One of the nodes has an additional ethernet interface acting as a VLAN trunk. This node also contains a VM with PFsense, managing...

I am not using Ceph, Now I read at https://ralf-peter-kleinert.de/linux-server/proxmox-pve8-to-pve9-upgrade.html with PVE9 I need Ceph. Is that true and what does that mean for my cluster. What have I to do.

Hallo Zusammen, seit 3 Tagen läuft mein Proxmox Cluster mehr oder weniger. Gestern hatte ich das altbekannte Intel e1000 Problem. Das konnte behoben werden. Gestern Abend war mir schon aufgefallen, dass es beim PBS Backup nicht VMs richtig gesichert hat und scheint eine Migration während des...

Hallo Zusammen, ich arbeite sehr viel mit Vlans für die Netzwerksegmentierung und auch wegen der Sicherheit. Bisher habe ich die meisten Erfahrungen mit VMware und Hyper-V und stelle mich jetzt langfristig auf Proxmox ein. Ich bin gerade dabei ein Proxmox Cluster aufzubauen und dabei kam mir das...

I have a PVE 8.3 cluster with 3 nodes ( dell R450 ), using pveceph for storage. Recently one node was down( hardware issue) ,then I recovered the system and wanted to re-install the PVE8.3 but I don't find PVE8.3 ISO on the website. I just download a PVE8.4 ISO and installed. Now the new...

Hi, I made a bit of a mistake :) I changed my ips on my two nodes which were on a 10.0.0.x, for reasons i had to change my network to 192.168.1.x, Stupidly i thought i could just go in to each node on my cluster and change ip in the GUI and the jobs done. Whoops how wrong i was. How do i...

"Hi, I am setting up a 3-node Proxmox cluster (WIK-1, WIK-2, WIK-3). I want to do it the right way from the start by separating the cluster traffic (Corosync) from the management/VM traffic. My setup: Management Network: 192.168.120.0/24 (GUI access, Web, etc.) Cluster Network (Dedicated...

Hi all, I’m putting together a Proxmox cluster with Ceph for HA and wanted to get some feedback before I go ahead and deploy everything. What I’m aiming for is fairly simple: I want proper HA with no data loss and automatic failover, but at the same time I’d still like one node (an R640) to...

Hello ! Setup : 3 nodes cluster (important, nodes are on DIFFERENT physical sites, and I'm assuming no private network between them, to be extra cautious), added all nodes in a SDN vxlan zone + created a VNet (subnet 10.6.6.0/24 with gateway = 10.6.6.1) installed OPNSense in a VM on node 1...

Hi Proxmox community, I am currently running a 3 nodes cluster and all my VMs disks are stored on NFS shares provided by another physical server. As that NFS server is a SPOF, I would like to replicate the VM and their disks on my third node : pve1 and pve2 have access to the nfs shares named...

Hello, I am experiencing an issue with my cluster and would appreciate your advice. Problem description: I am constantly seeing Corosync-related messages (flapping/instability), even though there are no visible link issues. Linux does not report any port or link failures. Switch monitoring...

I have a program that executes on proxmox PVE nodes and has to ensure that one of its critical sections will only run on *one* of all involved cluster node at the same time. It's a low-volume thing (the mutex will have to be acquired rarely), but it must work reliably. Will something to the...

I have a node with hardware failure, its resurrection has been deferred repeatedly now (soon a year). HA votes are set to 0, quorum and capacity is OK with the remaining odd number of nodes. The rest of the nodes have been receiving updates as usual. Are there any gotchas for keeping a node...

Hello, I am facing a design question regarding VM replication between two independent Proxmox clusters. Environment Two separate Proxmox clusters (Cluster A and Cluster B) No shared cluster configuration Both clusters use LVM storage (no ZFS) Inter-site VPN link Proxmox Backup Server...
