    2 Node HA with external QDevice

    We are currently running a single proxmox server to host our VMs, and I would like to build some redundancy. I was thinking of ordering an identical spec server to basically have a mirror. We also have some old servers laying around we can use for the quorum as I've read that you need 3 servers...

    iSCSI, LVM and HA confusion

    So I have a simple 3-node Proxmox lab + Synology NAS. My goal is to be able to build images using Hashicorp Packer and create VM's using Terraform declarations based on those images later. As far as I understand in order to create a VM from an image the storage of this image must exist on a...

    [SOLVED] HA Migration creates a lot of dublicate disks

    I have a Cluster of 3 and would like to migrate them. However we found out that it just creates a lot of dublicate disks. So I have been migrating a TestMigrationVM around all 3 nodes. I would like to post the Output of a Migrationg which takes really long for just one disk of 8GiB. I have no...

    Does cronjob work when quorum is not available?

    Hello, I have a three node cluster (n1, n2, n3). n1 and n3 are always running, n2 is kind of a cold standby. I just wrote a short script, where n1 or n3 are powering n2 on, when each other node is not available. It's my intention to have a valid quorum (2 of 3). The script works perfectly when...

    [SOLVED] Why does my PVE-Cluster migrate VMs and CTs when issueing the start command?

    This has started happening ever since PVE 7.4.x I can reproduce the issue 100% of the time when (bulk) stopping VMs and CTs on one Node, then (bulk) starting them back up again. As soon as the start command is issued, the VMs and CTs will migrate to a different Node, although they should just...

    [SOLVED] High availability with 2 VMs

    I want a highly available OPNsense setup in my Proxmox cluster. OPNsense has native HA features, but they require some manual tweaking to set up and I don't want to run a separate OPNsense VM for each node in my cluster. So I had the idea of just setting up two VMs on separate nodes and have...

    Hi. I have multiple proxmox 7 clusters for different needs. On a "staging" cluster (for staging / preproduction infrastructure) I don't have any HA. But on the production cluster, I configure two ceph storages (SSD and HDD). Developers have always pointed out to me that deploying code is...

    Ceph konfiguration "which node is on which USV" for ideal replication?

    Hi All, I have a 6 node proxmox setup with Intel Nucs in my house as HA cluster. Currently I use Glusterfs to provide a shared FS, but I think about changing to Ceph. The Nucs are spread over 3 places in the house with own USVs and in sum provide a big "distributed replicated storage" - that...
