    How does PVE handle Host related failures with HA

    Hi Community We run a VMware environment and seeing some issues with HA failing to detect a host issue and move VM's to functioning hosts.

    Best option for getting HA to work across two servers?

    Hi, I recently scored a good deal on two used Fujitsu TX100 S3p servers. I seem to remember Proxmox supporting the use of a quorum disk to replace the third required node in a cluster so I wanted to set these two servers up as a HA Proxmox cluster with external iSCSI storage. However the...

    [SOLVED] HA VMs and Containers Freeze on Node Thermal Shutdown

    Hi folks, I'm having an annoying issue with Proxmox HA + Ceph clusters on HP Proliant hardware. Whenever a component fails (Fan in this case), the server powers itself down to prevent data loss. The problem is that this tells Proxmox HA to shutdown all VMs and CTs living on that node as part of...

    HA delays and locking issues

    We are currently running tests on a new three node HA cluster configured with 2x10G networking and shared (Ceph) storage. We are using the latest stable packages for Proxmox 5.3. The behaviour around reboots of servers is nowhere near as smooth as we would like. These are the issues that we...

    [SOLVED] cannot start ha resource when ceph in health_warn state

    Hi, I'm playing with proxmox, ha and ceph in testing environment. So I set up 3 ceph enabled proxmox nodes including 3 ceph monitors but with an ceph pool of two nodes available/one required. I think this can be the smallest ha configuration possible. (So third node is only for quorum and...
