Hello, as the title says I copied over my boot drive (128GB) to another bigger (256GB) drive and even though it says it is 256GB (see attached picture), I cannot seem to figure out how to use the other 128GB that is missing. I did not initialize the new SSD (256GB) with GPT before I copied the boot drive (128GB) to it, could that be the issue? I am quite new to Proxmox so I would like some guidance on how to fix this issue.

Make sure you have backups of anything critical before you do any of the procedures!

I refer you to a recent post of mine - on the procedures required in your case.
