cluster

Hallo zusammen, ich bin derzeit dabei, ein Homelab zu planen. Es gibt jedoch noch einige Bereiche, bei denen ich unsicher bin, ob sie umsetzbar sind. Meine Idee ist es, ein HA-Cluster mit 3x U59, jeweils mit 16 GB RAM und 500 GB SDD, zu betreiben. Nun habe ich zwei Fragen zum Setup: Ist es...

Hi, I see that systemd-timesyncd is not installed by default. I was questioning myself, what if I do install it? Isn't timekeeping important for cluster operations? Thank you

Hi All, The procedure on how to upgrade pve 7.2 to 7.3 in a 3 nodes production cluster? Likewise in VMware, need to mark a node as Maintenance Mode, all the VMs will migrate to other available nodes. Once in Maintenance mode, you can patch or update the ESXi image. Upon upgrade completed, exit...

I am trialing 3 nodes PVE with cluster and CEPH. Should I setup the cluster first or CEPH first.

Hi, We have 7 node cluster and it was working well till yesterday, suddenly it got an issue, VMs stopped, the cluster was not stable, etc, randomly I shut down node 3, then all issues were resolved, and the cluster is working fine, then started the node again to test, as soon as the node up...

Hello all, I've been experimenting with creating a remote cluster using tinc and openvpn, both solutions seem overly complicated. Why not this; device 1 (IP: 10.10.10.10) sudo modprobe tun sudo ip tuntap add dev tun0 mode tun sudo ip link set dev tun0 up sudo ip addr add 192.168.69.1/24 dev...

Hi to all i am very new in proxmox environment, so maybe it is a basic question but i am unsure how to proceed there is a cluster with 6 node call it sm7,8,9,10,11,12 well, when i assembled the cluster, every node was in good shape, but... last pc start to behave oddly so i want to remove it...

Hopefully I'm posting this in the correct place, I rarely have occasion to post on here. I recently setup a cluster with two boxes, mostly because I was curious how it worked. I turned off one part of the cluster because I wasn't using it, then noticed I could not NoVNC into the VMs I had on the...

Hello everybody, First of all, a big thank you to the Proxmox developer community. I have been using Proxmox for several years now with GlusterFS and it works perfectly.Exactly, I'm using a Proxmox cluster of 3 Proxmox servers with a GlusterFS cluster for identical storage on each Proxmox...

Hello, I’m currently installing 3 pve hosts in cluster mode with an iSCSI EMC array, everything is redundant : 2 ToR switches for the servers , 2 switches for the iscsi traffic. We’ve chosen this solutions to migrate from ESX (too expensive). I’ve read a few articles / posts related to PVE...

Good day to all, The following scenario: A server with a PFSense, not virtualized, not part of the cluster. A cluster with various nodes. Some of them have only one NIC, some have multiple NICs. The complete As a goal I would like all cluster nodes to have access to a specific lan of the...

Hi, what is the recommended procedure to shutdown a complete PVE cluster including HA resources? The manual only talks about maintenance of single nodes, but sometimes it is necessary to shutdown everything. We have observed that a simple shutdown on all nodes is not sufficient as HA fencing...

Hi everyone, I'm having some performance issues with the Proxmox API on my cluster. As the number of users and virtual machines grows, the API becomes slower and slower to respond. I've already checked that the hardware is top-notch and the servers have enough resources, and I've also checked...

New Proxmox user here. I have a Proxmox Node (call it Node 1) that has numerous hard drive bays and just added another node from an older Optiplex 7010 SFF with 4 cores, 32GB RAM and is very limited on the number of drives I can install (call it Node 2). Currently I have TrueNAS installed on...

Hi! I'm implementing 3-node Proxmox cluster with CEPH storage. Each node has 4Gbit LACP interface (made of 4*1Gbit physical) as a public, and two 10Gbit interfaces for CEPH traffic. Is it a good idea to have Cluster and CEPH traffic both on 10Gbit interface? Or should I use public interface...

Hey yall, my 2 Node Cluster started to do weird things I cant explain - at least for now. All nodes run on the latest 7.3.4 release. Serv1 seems to be offline? It can be pinged, and I can open terminals (even from VMs), view stats etc. It is marked with a question mark from both...

Greetings Yesterday I installed my first Proxmox Backup Server ; I was able to easily add it as Storage to my cluster. However, I can access it only from the node I was connected to when adding the storage ; other nodes see it as "not online (500)". The storage was configured for "all nodes"...

After this forum could already greatly help me with a cluster issue, i now have more of a question than an issue. Ive recently tried to improve my cluster a little and one of the things i did was moving all vms to a shared storage, to make migrations way faster, which works great. Now as i...

Hey. Im running out of ideas on how to re-add a node to my existing cluster. This node was previously part of the cluster, but i had to temporarily use the server elsewhere. Ive reinstalled proxmox but i just cant add it to the cluster (with 2 other nodes) anymore. As far as i can tell the two...

I have 2 proxmox servers (proxmox-1, proxmox-3, both PVE 7.3). After creating a cluster on proxmox-1 and joining it on proxmox-3, I see additional disks on proxmox-3 host in the UI, with the same names as the disks on proxmox-1, but in status "unknown": /etc/pve/storage.cfg on both nodes (looks...
