Unable to use increased disk capacity

On my installed server, there was a smartarray p420, raid5 with a 3x 2 tb disk on it. proxmox lover was seeing the 4 tb disk. I added 1 more 2tb disk to my raid build. Proxmox saw the new disk size, but the sda3 size did not grow. What command do I need to use for proxmox to recognize this disk size?

I had resized the disk with gparted before, but again, proxmox did not see the 2 tb part.

I resized sda3 with parted now I can see the whole disk but it still shows missing in lvm-thin.

1.) resize partitions + fix backup MBR/GPT header (you probably did that with gparted)
2.) resize VG
3.) resize LVs
4.) resize filesystems (only for guests or if you want local to be bigger)

For 2 and 3 see see the vgextend and lvextend commands.
