high avaibility

I have two nodes cluster setup (actually three nodes with the third used for quorum). I'm using LVM volume storage (not thin provisioning) on top of DRBD on first two nodes. The LVM storage is marked as "shared". I created an LXC container and can migrate it between nodes without any problem...

Hello, I'm looking into a new setup using Proxmox. I will have 4 x Proxmox Nodes, each with a FC HBA. These will be connected to another Server with FC HBA in target mode, running FreeBSD or Linux (not sure yet) with 2 zpools (we will have different storage for SSDs and HDDs). What is not...

Good morning everyone, I'm posting today because i would like to use the great HA features that proxmox offers but it seems some variable is not defined so when i try to migrate manually (with the gui or with "ha-manager migrate vm:100 proxmox4") the VM it doesn't work. The problem that pops...

Note: I've changed the actual domain name to 'x.nl'. I'm trying to configure a two-node cluster on Proxmox VE 3.4. What I've done so far: Created the cluster; Created fencing users using IPMItool; Joined the second node (px01) to the cluster created on the first node (px01); Created a new...

Hi, We are testing a Proxmox Cluster. I want to setup IPMI or Hardware Watchdog (Intel) Fencing. However the documentation i found in https://pve.proxmox.com/wiki/Fencing seems to be outdated and the admin guide just refers to "/etc/default/pve-ha-manager", where I could enable the line...

Hello, I have a three nodes cluster and all seems to be running ok. All VM's are connected with iSCSI shared storage and I can live migrate from a node to another without problems in few milliseconds. However, the other day a node rebooted without apparent reason and the only VM managed by HA...

Hello, I just realized that a node of my PVE HA cluster rebooted w/out apparent reason so I wanted to make some troubleshooting. I have the feeling that the soft watchdog could be responsible for this, maybe due to some misconfiguration with the time server. Is it possible to understand if the...

Hello everybody! There is a cluster of two nodes (Proxmox 4.3, HP DL380 G9 Servers), HP MSA 2040 SAN connected via FC 8Gb. LVM shared for both nodes. Online and offline migration goes perfectly. The problem is when we are testing HA and restart to the one node or make disconnection to the...

We are currently using 2 identical KVM servers which are manually managed (not Proxmox). We want to move to a 3-node HA Proxmox PVE cluster using Ceph for storage. We only have 3 identical servers in total (2 of which are currently in use), and are looking for a way to migrate to the new...

Hi, this is my first post on this forum, i work with proxmox on my servers from version 2.x and I think this software is very powerful. Actually I’ve 3 cluster with drbd (6 servers) and some stand alone installation for a total of 22 proxmox installed. I'm planning to install a Proxmox cluster...

guys, i've installed a two node + quorum disk cluster following wiki articles all is built on two hp proliand dl360 gen 9 servers + shared hp msa 2040 sas 6g storage box with multipath quorum is provided by an iscsi target placed on a qnap nas... all seems working fine, tests operated with...

Dear all, Sorry for the stupid question. I've a three nodes cluster running PVE 4.1. On one of the nodes, yesterday, the latest package upgrades were manually updated, including alle the pve debs and the latest kernel. Before the upgrade, all the running VMs were migrated to the other hosts...

Hello, Fist of all, congratulations to the Proxmox team who did a really great job! I'm triyng to setup a 2 nodes high avaibility configuration with a 3rd node for quorum with DRBD9, all nodes runs Proxmox 4.1. I found this Wiki page who describes how to accomplish this, and it worked without...

Hi, I'm trying to setup an HA cluster on OVH servers, using a vRack and glusterFS for the storage. I configured everything on the 3 nodes, and installed a VM for testing. It runs fine, I can do live migration between the hosts and if I reboot a node (properly, with the actual reboot command)...

Hi All, I'm currently evaluating ProxMox and love what I see so far. I've got a couple of questions though. Am I correct in my understanding that Ceph cannot be mounted like a normal drive or NFS? It can't be RSYNC'd to and from directly from a host node? (Why would I want to? I like the...

Hi I’m going to set-up a storage connected to 2 servers using iSCSI, and I would like to achieve HA of a VM (Windows based). I need only one working at a time without load balancing just like to HA Proxmox feature. However, I would like to switch to the second node not only for hardware...

I can't seem to find a guide anywhere for the process of adding a new node into a ceph system in proxmox once an HA system is already active. I've found guides for setting them up, but once a system is in place what are the steps? I tried: updating proxmox to the same version as the other...

A previous post was taken down for mentioning a competitor so I won't mention them here and sorry if this is the wrong place for a feature request but there doesn't seem to be a place in the forums to ask. In this other hypervisor, storage was done locally on the nodes (as opposed to a central...

I'm using Proxmox 4.0, i have three nodes and i want to run High Avaibility. To do so i need to configure Fencing but i couldnt find "/etc/default/redhat-cluster-pve" Can anyone give me a good tutorial to run HA ? is it ok to run HA now with3 nodes and then add other nodes ?
