I am sorry if this is a dumb question covered in the documentation or already answered in the forums, but I have looked and can't find any answer I understand. I just purchased a 2TB nvme drive for my proxmox machine, used clonezilla to clone the original 128GB ssd to the new 2TB nvme. even though I got stuck in a loop when using clonezilla, I pulled the power cord at just the right time after "cloned success" and rebooted successfully to new drive. as I feared, it did not automatically expand the LVM partition (that's what I wanted, right?) how do I expand my partition the right way with proxmox? thanks.

You need to do that on your own using the CLI. First you need to expand your partition that stores the LVM (for example using fdisk or parted using the CLI or you boot into a gparted ISO to have a GUI). Then you have to extend the VG of the LVM using the vgextend command. Then extend the LVs using the lvextend command. Then you can use growfs or resize2fs or something similar to extend the filesystem of the root LV.

Might be easier to just install a new fresh PVE and then restore the guests from backups.

thanks, but that is way over may pay grade. If I knew how to do any of what you just said, I probably wouldn't have asked the question in the first place.

There are four steps you need to do.
  1. Resize partition to 100%
    • You can do this via fdisk. Run fdisk on /dev/nvme0n1, note the start sector of partition 3, delete partition 3, create a new partition 3, set the end sector to the last available sector and don't remove LVM2_member signature! Then change type of the newly created partition to 30 (Linux LVM) and write the changes to disk.
  2. Notify the OS of the partition changes or simply reboot the server.
    • Code: 
      partx -u /dev/nvme0n1p3
  3. Grow the physical volume of your LVM.
    • Code: 
      pvresize /dev/nvme0n1p3
  4. Expand your locical volume.
    • Use all the new space
      Code: 
      lvresize -L +100%FREE pve/data
      or only 100 GB
      Code: 
      lvextend -L+100G pve/data

After searching for hours this is what helped me out after swapping to a bigger drive!
Many thanks

This was very helpful, though to resize by a percentage, I needed to use the lowercase "-l" option:
Bash: 
lvresize -l +100%FREE pve/data
