Hey everyone, I’m currently using proxmox to virtualize my OPNsense and another VM. Today when I went to create a third VM, everything crashed with I/O errors, and I realized my local-lvm was out of space. This was odd to me since I have a 1TB drive and only have two small VMs.

To my surprise, proxmox is only using 100GB of my disk. Can someone please guide me on how I can fix this without having to reinstall proxmox? I would prefer to have my OPNsense VM running while I fix this. Here are some diagnostics to help. Thanks

    I can’t give you specifics but generally what is likely necessary:

    1. Backup anything important. You will be doing things that risk loosing data.
    2. Make a bootable USB with a live Linux.
    3. Look up instructions on resizing partitions.
    4. Boot into the live Linux from the USB
    5. Resize your existing Proxmox partition

        I’ve done it before, but there’s always a lot of googling involved. I think a combination of vgdisplay and vgextend may help: https://www.redhat.com/sysadmin/resize-lvm-simple

        If sda3 is really <100GB it gets a lot scarier but is likely still doable.

        I’m not a fan of Proxmox’s partitioning scheme and usually use a separate drive for the OS and the VMs because of this exact scenario.

          That led me in the right direction!

          Fixed it with:

          pvresize /dev/sda3

          lvresize --extents +100%FREE --resizefs /dev/pve/data

          Thank you!
