Extend local-lvm proxmox

[Vicemi]

I have recently changed the NVME of my proxmox server, before I had a 1tb NVME and now I have changed it for a 2tb, what happens is that I have cloned everything from the 1tb disk to the 2tb disk, but proxmox still recognizes the local-lvm as 1tb, and I want to expand it and put more storage.

[s.lendl]

I see that your underlying partition is already in the correct size (1.8T)

Now you can resize the filesystem.

You can view the state of the pysical volume (PV) with

pvs

You need to resize the PV with

pvresize /dev/nvme1n1p3

now the logical volume (LV) has free space to grow as shown with:

vgs

To resize the LV to the full size of the PV

lvextend -l "+100%FREE" /dev/pve/data

also interesting in this context:

pvdisplay
vgdisplay
lvdisplay

Have 1 command missed to extend the LVM: resize2fs /dev/<partitionname>

1. if you have plan to use disk space used by another LVM, first remove it on Proxmox
2. run: lvextend -l "+100%FREE" /dev/pve/<lvname> # your get lvname running command "lvs" - example: root
3. run: resize2fs /dev/<partitionname> # you get partitionname running "ldisk -l" - example: /dev/mapper/pve-root
