Thank you for your patience, I know there are a lot of threads similar to this, and I've read them, but I must be missing something.

I recently went from a 500 gig proxmox drive to a 1tb drive. I copied the drive and I thought I went through the right steps to extend the partition and volume group and I think maybe theres something I still need to do.

Code: 
root@proxmox:~# pvs
  PV             VG  Fmt  Attr PSize    PFree
  /dev/nvme0n1p3 pve lvm2 a--  <930.51g    0

Code:

  (and more continued... but not relevant)

Code:

I may be completely wrong, but I think the PV and VG are fully sized. I want to extend the LV known as data in order to store more vm-xxx-disk-x files (container data).

The /pve/data shows a size of 337G which I want to increase to full size. I dont want to mess with the metadata size.

So I did:
Code: 
root@proxmox:~# lvextend -l +100%FREE /dev/pve/data
  New size (86493 extents) matches existing size (86493 extents).

(no change)
Code: 
root@proxmox:~# resize2fs /dev/mapper/pve-root
resize2fs 1.47.0 (5-Feb-2023)
The filesystem is already 151454720 (4k) blocks long.  Nothing to do!

Code: 
root@proxmox:~# lsblk -f

  (etc...)

I think what I need is resize2fs then maybe e2fsck .. but it seems that's done.

Code: 
root@proxmox:~# resize2fs /dev/mapper/pve-root
resize2fs 1.47.0 (5-Feb-2023)
The filesystem is already 151454720 (4k) blocks long.  Nothing to do!


I've been at this for days. What am I missing?

Thanks so much!

I think I may have figured it out. I booted into gparted, went into terminal and looked at the structure via lvs.

I used the lvreduce -L 100G -r pve/root to reduce the size of the local volume to 100G
then
lvextend -l 100%FREE -r pve/data to expand the size of local-lvm to the max.

Then rebooted.

lvs looks much better now:

Code: 
root@proxmox:~# lvs
  LV                                    VG  Attr       LSize    Pool Origin        Data%  Meta%  Move Log Cpy%Sync Convert
  data                                  pve twi-aotz-- <815.62g                    38.78  3.69                           
  root                                  pve -wi-ao----  100.00g

Hopefully this helps someone else out.

Hello, I'm from Colombia also new to Proxmox, I'm trying to expand the LV to be able to make a backup of a machine and it's not enough, with this node I have of 512 gb, I haven't found that
