Hello,
I've searched and haven't been able to find what I'm looking for. Apologies if I've missed it.
We're running PVE 7.4-3 and we have a cluster of 11 nodes in various data centres around the world. We're having some corosync problems and also 3 of the nodes really belong in their own...
I got some leftover servers from work and Im going to setup a small proxmox cluster
I need some tips and ideas how to best utilize the hardware
3x HP dl360 g9 2x16core, 128GB ddr4 ram, 8x300GB
1x HP dl380 g7 2x6 core, 288GB ddr3 ram, 2x300GB
I also got a old dell with 6x1tb that I though...
Hello,
I'm in the process of planning out a 3-node cluster for failover and high availability and have a question about where to store the VMs. Assume the following;
All servers are on a 10GB backbone
All servers have SSDs for OS and data drives
All 3 PVE nodes are identical. Same...
I'm trying to figure out the best way to ensure corosync has its own network. Please let me know if any of these points weren't ideal and why:
I created a VLAN with no gateway (just a space on my switch with a unique subnet) 10.5.0.X and set all 8x of my nodes to addresses on that subnet.
I...
Hello everyone,
so a few days ago the electricity failed in my homeoffice and the small homelab for Home purposes failed.
One node was complelty failing until the point the ssd inside was basically dead. It could boot, sometimes but after a few minutes went offline again due I/O error.
I came...
I'm looking to setup a PVE cluster, mostly for the benefit of being able to move VMs from one machine to the other and for high availability. In reading the PvE8 admin guide I came across this line:
This is a real bummer since I have a mixed Epyc and embedded Xeon CPU environment. I have...
Hi
I'm plan to setup a 3 Node HA Cluster with 3 HP DL380 G9 Servers.
They have all 2x 10G NIC's.
Now I'm not sure what the best option for storage would be.
The following option / hardware i have available:
- Local Disk's with Ceph
- Dell MD3620 SAN
- EMC VNXe3200 FC SAN
- HP MSA 2040...
I'm facing the following issue on
pve-manager/8.0.4/d258a813cfa6b390 (running kernel: 6.2.16-8-pve)
that i can't edit files in /etc/pve due of permisson errors. root has only read-only rights on this config files.
But i has to edit those files as root, due of issues with the otp auth...
We are organising a Proxmox VE day in the Netherlands, Ede on Thursday on the 12th of October 2023.
In the morning, we will discuss how you can innovatively meet your virtualisation, storage and private cloud needs within your budget with Proxmox VE. We will also look at how to easily achieve...
I've spent so many hours and pulled too many hairs for this already.
TLDR: Migrating a VM fails because ssh of the target node listens on IPv6 only (as desired+configured), and migration is attempting connection to IPv4.
All I want is the connection to go through IPv6, or the VPN IP.
The...
Hello,
I have a cluster and one of the nodes is a ZimaBoard. Everything runs fine, but when I try to do a backup of my CT the backup job is stuck and nothing is happening. It doesn't matter if the backup storage is the local SSD or a NFS or PBS - same behaviour.
Example:
Node name: "darwin"...
Hello all, this is my first post on the forum.
I have a proxmox cluster installation with ceph that is broken and need help recovering it.
After a network device stole the IP address of one of the nodes, ceph went down and never recovered.
I tried troubleshooting with a proxmox silver partner...
Hi!
i am running a cluster with multiple PVE nodes (all on Ver 7.4) but i am currently facing an issue with one of them. So now i would like to ask you for any hints, maybe i just simply overlooked something silly.
I just recently joined two more nodes into the cluster, which worked without any...
Hi,
I want to connect my external proxmox server which is in other network with my local cluster currently with 3 nodes connected.
I tried installing a VPN in the external server but when I try to join the cluster I got this error during the conection:
permission denied - invalid PVE ticket...
I was able to join a node to a cluster, but later I had to reinstall the node from scratch, without previously removing it from the cluster, and when I want to join it again it generates the error: tls_process_server_certificate: certificate verify failed (596).
What should I do?
Hello everyone,
maybe this question got asked somewhere but I couldnt find it:
Is it possible to remove the HA functunality and use the cluster only as config cluster?
So that the information about Storage user etc. are shared but no HA so I can turn on/off hosts if needed?
Kind regards,
Eigentlich nutze ich Blockstorage nicht, aber dank dem Hinweis von Falk wegen NVME-oF wollte ich mal den Einsatz von Blockstorage testen. Ich habe einen Node mit LVM und einen Node mit BTRFS aufgesetzt. Dann habe ich dem einem 'nen iSCSI-Storage zugewiesen. Damit der anderen den auch sieht und...
A single node is grayed out, this has happened before and succesfully cleared with
systemctl restart pvestatd
but it keeps recurring so I checked my logs:
There was an uptick around 13:00 so I honed in on that to find that these error messages suddenly started appearing over and over...
Hello, I have a Proxmox VE cluster with three nodes. One of these I use to access the cluster via the WebUI. For the other nodes, I cannot see individual graphs in the Summary tab, but instants are available. How can I debug this issue?
The nodes are running the same versions of packages. I'm...
Hi everyone,
I have a 3 nodes cluster running on PVE 6.4 with a total of 24 SSDs with CEPH.
Considering that:
- the cluster can be brought to a total stop
- each node is more than capable to host all the machines
- new SSDs are bigger (from 960GB to 1.92TB)
- I'd highly prefer to not stress the...
