    Expected backup speed

    I just created a new proxmox backup server and made my first test. The backup storage consists of 4 vdevs with a raidz1 that is build with 3x 18TB Seagate EXOS (ST18000NM000J) HDDs. I also add a log mirrored vdev that uses two Intel Optane NVMe. The network is a bond of two 10GbE cards. The...

    I'm currently playing with PBS and wonder if proxmox and pbs can share a ZFS volume? I've create a zfs subvol for VM data and one for PBS but currently after a reboot the shared zfs volume is unavaiable for proxmox. After searching a bit I found the message: Nov 17 11:19:36...

    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...

    Windows Server 2012 guest agent won't install

    I enabled qemu guest agent support with "qm set 170 -agent true" and verified that the agent option is used (kvm is running with -device virtserialport,chardev=qga0,name=org.qemu.guest_agent.0). So I assume the host part is ok. But if I try to install the client side (the qemu-ga-x64.msi from...

    Backup failed because of "empty device list"

    I'm running Proxmox 3.1 and recently added a new VM with an empty device list. The VM just boots an ISO image (kind of special firewall) and has no local disk attached. This works pretty well but the daily backup complains about an "empty device list". I could remove the VM at all from the...
