  1. Migration ohne Shared Storage

    Hallo zusammen. Ist es möglich die Migration, gerne auch offline, ohne Shared-Storage zu nutzen, dass also bei der Migration gleichzeitig automatisch das Image auf ein lokales Medium einer anderen Node umgezogen wird? Wenn ich das ohne Shared-Storage versuche, dann bekomme ich die Meldung...

    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...
  4. Default Storage von local-zfs zu anderem Pool

    Hallo, ich bin ein eher stiller Mitleser und Selbstlöser durch bekannte Beiträge, aber irgendwie komme ich hier nicht weiter: Was ich möchte: VMs und CTs von einem alten Node zu einem neuen Node umziehen. Mein Problem derzeit ist, dass das local-zfs zu klein ist (< 30GiB) um größere VMs zu...

  6. [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...

  8. New proxmox cluster separated or join to existing?

    Hi all, we have a production running cluster of 4 nodes version 5.4 with CEPH over SATA disks, 4 monitors, 1GB/s network cards. We have purchased 4 new servers, all with SSD's and 10GBe NIC's. As at least half of the containers and VM's on the existing SATA cluster will have to be migrated to...
  9. 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...
  10. 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. This has prompted my question today about how PVE manages hosts that have partially failed and are not 100% responsive but responsive enough to respond to...
  11. Komisches Verhalten beim Migrieren

    Hallo, Wir haben einen neuen Proxmox Server da die anderen 4 im selben Cluster bald voll sind. Nun wollten wir einige wichtige Server die mehr Leistung brauchen migrieren. Der erste Server war kein Problem. Die Migration verlief problemlos. Beim zweiten funktionierte ebenfalls alles...

  13. How to migrate from a KVM virtual machine to a LXC container?

    Hello, I have a virtual machine which has a hard disk drive running on an LVM volume. I don't see how to migrate it to an LXC container without going through a traditional migration. I saw a tutorial -"How to convert a KVM image to a LXC container ? ", but it doesn't seem to be applicable to...
  14. [SOLVED] TASK ERROR: migration problems

    Good morning, I can't migrate a VM from a host to another when it's powered on only (with a powered off VM it's working fine). Here's the log : 2019-06-03 11:17:49 starting migration of VM 114 to node 'btz-pve2103' (192.168.32.62) 2019-06-03 11:17:49 copying disk images 2019-06-03 11:17:49...
  15. Migrating ZFS data storage from one host to another

    Hi! Currently I have my Proxmox installed in a (let's call it) host_A, and I need to migrate the whole installation (VMs, CTs and ZFS data storage) to another host (let's call it) host_B. Host_B is another computer, with his own motherboard, CPU, memory and disks. After this migration, host_A...
  16. Offline Migration extremely slow

    Hey, I noticed a huge issue. When I try to migrate a VM to a different node I get extremely slow transfer rates. This is unexpected since I use a dedicated Gigabit network for migration (which is unused except for migrations). Unsecure flag is set aswell. Have a look on this migration log...
  17. 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...
  18. Slow HA migration of VM with shared storage

    Hello. HA migration of VM between two nodes was really slow (speed: 9.19 MB/s). Total ram of VM is 8 gb. Storage is shared (Ceph external). Network speed between nodes is 10 Gbits/sec. Usually migration speed is something like in this example: (1365.33 MB/s - downtime 90 ms). Can you please...
  19. Umzug einer virt. Fetsplatte in andere VM?

    Hallo, ich möchte gerne eine VHD, die als "Daten-VHD" einer VM dient zu einer neuen VM "umziehen". Da ich dies noch nie gemacht habe und auf der umzuziehenden VHD mehr Daten sind als ich momentan zwischenspeichern könnte, möchte ich sicherheitshalber nachfragen: Ist...
