    It just occurred to me that the Reason why I'm getting such a MASSIVE overhead on my Backup Server (which has 2 x RAIDZ-2 x 6 Disks each) is because the Default ZVOL on Proxmox VE is (or probably "was" for a long Time, and many of my Virtual Disks are quite Old) 8k, which results in a Space...

I'm currently running Proxmox 8.1 and originally had a Ubuntu Server VM set up for months, which I've loaded data on my hard drive in path /mnt/WD14-1 through two separate virtual disks (/dev/sdb1 mounted to /mnt/WD14-1/sdb1/, /dev/sdb2 mounted to /mnt/WD14-1/sdb2/).

    Hello from France, I'm asking for some guidance/better explanations about something I'm trying to do with some Virtual Machines under Proxmox VE. I'm using IaC tools (Terraform / Terragrunt).

    can a VM be restored from a .qcow2 disk image?

    Hello, I had a problem with my managed VPS provider, the data was lost and I am not responsible. It only sent me a disk image of the virtual machine in .qcow2 format and I have no idea how to use it to recover a cpanel account that I had there (1 website). Could I use promox to restore this VM...

    Usable drive space to small and shows different sizes in each menu

    Hello, I got 3 Drives, each 279GiB installed as a raidz1. So the usable drive space should be ~558GiB (2x278GiB), but I am only able to use around 393 GiB. If I look at Storage -> My Storage -> Summary, then I can see that I am using almost 100% of the storage space, but there it says 536...

    Can't create VM disk with almost all the available size of the zfspool

    I create a zfs raidz1 with 3 x 4T disks and it shows that I have 7.04TiB available spaces. But when I try to add a new 6TiB(6144GiB) disk to a vm, it failed because of no space. How could that happen. That's a new raid I just created. When I lower the disk size to 5000GiB, it created...

    Storing backups to a disk in local-lvm

    Hello, I would like to backup my VMs onto local-lvm because my local disk is very small compared to the lvm disk (4TB versus 128GB).
