high availability

Hi, I have read just about every post on this forum on this topic. Some have some useful information, but I can't get all the answers that I have questions for, hence this post. I need to setup a 3 node high available cluster to host 14 virtual machines, Linux and Windows based. This is to...

Hi, I know from VMware vSphere three functionalities Admission Control Policy Takes care of redundancy (e.g. one host can fail and all VMs can still run and/or be restarted on the remaining resources) New VMs cannot be started or deployed if the resource is full High Availability I know...

Hello. I realize that at least 3 nodes are needed for a VM HA cluster. My question is whether 3 compute nodes + at least 1 management/control node are required in an HA setup, or is it possible for management and compute to be co-hosted on the same node/s?

Hi, In a 3 node CEPH/Proxmox 4 HA Cluster, I recently had a Windows 7 Guest VM hang (BSOD). As expected HA never kicked in because in proxmox' point of view the VM is up and running. I thought maybe the QEMU Guest Agent would help checking for hung VM's but when I checked the wiki page it only...

I have here a strange phenomen regarding the HA in my proxmox environment. I am using three server, called now PVE, PVE02 and PVE04 running proxmox 4.4. All three have been reinstalled by migrating all VMs to a remaining node, removing the node correctly after shutting it down, installing...

I'd like to know how you're doing backups in a HA environment. We have a Proxmox VE Cluster running on a SAN with all components at least twice, so anything can fail. At least in theory. Our weak spot is our backup system. Currently we're backing up via NFS to a server (server grade hardware)...

Hello fellas, thanks you in advance for reading this thread. I have 2 PVE with HA. Each server is running some VM. The problem/doubt I have is that, each machine has it's storage in local, and every week we do some backups in a NFS. Because we have HA set, if a PVE crashes, the machine tries...

Hi there, We are having trouble with a 3 nodes cluster that is rebooting every node simultaneously every few days. We are using OVH servers, so only unicast is available, OVH vracks being more expensive and we dont need more than 3 nodes. We are using software RAID with SSD drives and our VMs...

Hello, I'm willing to setup a Proxmox HA cluster based off three nodes, where one of them is virtualized onto a different host, since it's just for quorum purposes. I would like to have local redundant storage on both of the two mail nodes (and maybe even the third if needed for ceph), so I'm...

Hello, We have setup a three nodes cluster that's up and running. All nodes are using local ZFS storage (a bit annoying because PVE expects datasets to have the exact same name - which is not the case in our install). We also have 2 NFS servers (based on FreeNAS) : 1 used as a ZFS backup...

Hello, for a home lab I would like to setup a Proxmox VE 4.2 cluster with local storage for the VMs, mirrored presumably with DRBD9. However, I learned that I cannot implement HA without having a third node. I tryed learning why is that, and I stumbled upon concepts like quorum, split brain and...
