cluster

My working cluster consisted of 2 nodes. When I was adding the third node something went wrong. The process wasn't finished and just timed out. When I started to investigate possible reasons of such unexpected result, I noticed that I made a mistake while adding a new node to /etc/hosts file on...

Hey Guys, We have a cluster with 5 servers which is setup with High Availability for the VPS's... My only problem now is backups... I need to get a backup solution for the VPS's, so I was hoping to add 1 8TB drive to one of the servers, internal or external, and share it for all to make their...

I had a server die this past week and I removed it from the infrastructure. I can confirm that the server is out of commission and is pulled from the rack. I removed the node and all is well, or so I thought. The cluster is giving me an issue with regards to it seeming not being able to find the...

I realize this is my first post, because I tend to avoid asking questions if I can find the answer on my own. Currently I am unable to find a solution so: I was running one system with Proxmox and recent got some servers for cheap, so I decided to test out clusters and making my VMs HA...

Hi, i'm rebuilding a cluster. I've a single node cluster with lvm storage (node1). I tried to add a node (node2) to the cluster, Node2 have zfs storage (raid1) that works fine before i try to join to the cluster, Join process seems fine but after the join the zfs storage on gui is displayed as...

Hi, Basically what I want to achieve is having 2 node cluster with offsite backups for redundancy. In case of node 1 failing, I will restore backups on node 2 and proceed using it. The problem is Quorum on node 2 when node 1 is dead - node 2 does not have a quorum and therefore cannot start...

Hi, I have recently set-up a Proxmox VE cluster with 2 HPE DL380e Gen. 8. I’m now looking at the best way to have a segmented virtual network that could span the cluster nodes, so to ensure VMs on the same LAN can communicate to each other regardless of the host where they reside. I have...

Hello, I'd like to install a test cluster with shared iSCSI storage / SAN. I read that the recommended solution is to use it as storage Omnios/Comstar. Can anyone recommend an Omios compatible 40G QSFP+ network card? ( tested ) I'm reading Illumos compatibility list, but is not so reliable, i...

Hi all, I read a lot of documentation about Proxmox Ceph Cluster but I can't figure out the best solution for my case. I would like to configure a little 3 node cluster using Proxmox and Ceph with the ability of add in the future more nodes (so more CPU and RAM to the cluster) if needed or...

I think I'm in a bit of trouble here. We have a san and it took a lot of effort to get working, but eventually it did through some miracle. I added LVM on top and the first two memebs of the cluster saw it without trouble. Then I realised the other members of the cluster hadn't been set up to...

Hello, I want to add a new proxmox node server to a cluster, and my question is, is it possible to add a new node server with proxmox 6.1 to a proxmox cluster where the others nodes uses proxmox 5.1? If this is not possible, maybe proxmox 5.4 would be compatible with the cluster? If not...

[edit: removed cluster, rechecking.] [edit2: RESOLVED. it was the problem with the hard drives. removing them from /etc/fstab resulted in proxmox booting up normally] i have two proxmox servers (both on VE-6), added them together in a cluster for testing, everything worked fine the past month...

Hello I’ve been running a two-node cluster (haumea and makemake, yes I’m into transneptunian objects) for quite some time now, without any problem. Lately, I noticed that on the web interface, one node (makemake) was marked failed, but the containers inside it still worked, so I kept postponing...

Hello dear Community, I was wondering how do I set up it the Best Way. I have a simple 2 node test Lab. The Problem: I'm running on my first node a pf sense firewall which connects to WAN over vmbr0 and inject its "LAN" to vmbr100 So Basically every VM in vmbr100 is in the "LAN" Now I want to...

Hi there, We have a proxmox cluster, with each node in the same subnet. The cluster contained 3 hosts and everything worked as it should in the last years. Recently we wanted to add a new host to the cluster. This host is also in the same subnet, nothing changed in the network confugration...

I have a 3 node hobby cluster running on lenovo rd330's with ceph across all three nodes. I recently had disk failures in one of the nodes that required it be completely replaced. I reinstalled the node and went to add it to the cluster, however the old node was still being shown in the cluster...

After a recent SAN issue, it has been recommended that our cluster should be using multipath. In preparation, I installed the various software modules using apt-get but didn't realise that the installation would start the services. I have shutdown and disabled them but now seem to be stuck...

Hey. Earlier, I used version 5 and a cluster of 4 nodes, one of which was on another network with delays of 30-80ms. To work, I configured corosync to work with udpg and everything worked fine. When upgrading to version 6, I recommended updating corosync and removing the udpu settings as...

Hi, I'm testing proxmox, and I need to know, how to remove osd/mng/mon when one machine is out the cluster. Exemple, I have 4 machines, I removed one using of the command "pvecm delete exemple",but the configurations(OSDs, mom and mng) of removed machine stay in cluster. How to delete this...
