During that time, there was an hourly VM backup running. The backup didn't finish as the Proxmox VE node couldn't reach the backup server. I see the "GET" API request (return code 101) that starts the backup in the PBS API logs. The HTTP "PUT" to transfer the backup is missing. Unfortunately the backup's task log is missing. It obviously got rotated. During that time, the root filesystem of the VM changed to read-only. To find out if things are related or not, it'll be helpful for me to answer the following questions: 1) What happens when a Proxmox backup is started and PBS is not reachable anymore to transfer the backup? 2) In general, is there a (small) chance of a (failing) VM backup causing the filesystem to be read-only afterwards? I read that qemu-guest-agent calls fsfreeze during Proxmox VM backup. What are the impacts of fsfreeze? How are errors handled? Are there other potential risks? Here's the VM config: agent: 1 bios: seabios boot: cdn bootdisk: scsi0 cipassword: ********** ciuser: cloudadmin cores: 8 cpu: Skylake-Server-noTSX-IBRS description: VM Description hotplug: network,disk,usb kvm: 1 machine: q35 memory: 32768 name: vm-name net0: virtio=26:4B:29:B1:71:89,bridge=vmbr0,tag=37 numa: 0 onboot: 0 ostype: l26 protection: 1 rng0: source=/dev/urandom scsi0: ceph:vm-108-disk-0,size=255180M,ssd=1 scsihw: virtio-scsi-single serial0: socket smbios1: uuid=e8736d61-9a25-4f89-9f6d-a84ef25c42cc sockets: 1 tablet: 1 vga: qxl vmgenid: 9d3233e9-6bc1-43e8-be50-39597b6a5034 I highly appreciate any answers and thoughts!
