Proxmox Help (lemmy.dbzer0.com)

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'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!
