    Storage migration from ZFS to NFS fails for some containers

    I'm migrating from local storage to NFS. I powerdown the container before migration and start the storage migration. Some containers (about 30% I gues) fail.

    Some thoughts on making live storage migration better.

    We have 4 Proxmox host servers and two different NFS servers for VM storage. We usually we manually distribute the VM storage load between them. The two NFS storage servers are all flash and have 10 gig connections to our ProxMox hosts. A few times a year we need to update the firmware on our...

    [SOLVED] Qemu/disk migration network. Is it "Corosync/cluster" network, or native bridge?

    Greetings Proxmoxians! I've got a Proxmox network question that I hope someone can answer as I can't seem to find a clue myself. I've read through forums, best practices and the Admin Guide. There are 4 servers in a cluster. However, Ceph is not going to be used in this deployment, because...

    Feature request: VM migration (restart mode)

    In a replicated ZFS environment, containers can be easily migrated from one node to another, as the only supported migration mode of a running container is restart mode. It works quick and reliably if replication happends e.g. hourly or more often. For VMs, the system does not allow to select...

    Offline Migration extremely slow

    Migration from OpenNebula to Proxmox 5.x

    Hello, I need to migrate from OpenNebula to Proxmox VE. Given that they both use KVM in the back, it should be pretty easy. Even if we have to recreate the VMs, that shouldn’t be too big of a deal. The problem is that the disks (.qcow2 or .raw, depending on how old is the machine created) are...
