  1. fsfreeze-hook not called from vzdump snapshot

    I'm running proxmox-ve: 6.0-2 (running kernel: 5.0.21-5-pve) and as far as I understand "man vzdump" should run /etc/qemu/fsfreeze-hook if the qemu-guest-agent is installed and the kvm config contains "agent: 1". A "qm agent 6207 ping" from the proxmox host results in an entry in...

  6. Proxmox NFS Backup/Remote Snapshots

    Hi there, I currently have some VMs which are hosted on and run from a shared NFS share by the Proxmox hosts. I currently use Proxmox to backup (snapshot) these VMs back to the NFS share but this seems inefficient with the reads from NFS -> PVE host and writes back from PVE -> NFS host...

  9. Backup to NFS kills PVE Node

    I setup a new 5.3 two-node cluster and created some CT on a local LVM volume. When i backup a CT to a NFS storage it starts, says it cannot do snapshot and continues with suspend mode but never finishes. The node or better the PVE gui gets unresponsive, all NFS mounts hang and also a reboot is...

  12. Backup- und Restore - wie?

    Servus, ich plane, für ein Kleinstprojekt bei einem Kunden erstmals Proxmox statt VMware einzusetzen. Allerdings habe ich noch keine Ahnung, wie ich am Besten die Backups der 2-3 virtuellen Maschinen (1x Windows, 1x Ubuntu Server) vornehme? Die Datenmengen sind sehr überschaubar, sodass ich auf...

  14. Replication and Snapshots.

    Hello to all. I have used Proxmox since 3.4. the advances in the platform are definitely exciting to see! We are using zrep to sync zfs volumes to a non cluster machine at this time.

  16. [SOLVED] Can you perform an action without a log entry appearing in the cluster log?

    So I recently made a cron job that, every 6 hours, would take a snapshot of every VM (just to have faster and up-to-date backups to protect against user error). Everything is flawless and I have yet to encounter any issues. BUT there is one hiccup that is getting rather annoying: the cluster...

  19. Additional ZFS Volume and VM Snapshots

    I am currently using ZFS as my default storage solution for a one node PVE cluster. Each VM gets a RootFS- and SWAP-Volume from two different parts of the main pool. If a VM stores data (e.g. personal cloud), it gets an additional ZFS volume by path, so I will pass a block device like...
