Proxmox - Resize pve-root

proxmox_resize_pve-root

# Check disk space before
df -h

    # Delete local-lvm storage in gui

    lvremove /dev/pve/data

    lvresize -l +100%FREE /dev/pve/root

    resize2fs /dev/mapper/pve-root

# Check disk space after
df -h

Warning! This will destroy all your VMs, check before you do it.

Não consegui resolver com segurança meu problema com o método acima, então, fiz o seguinte:

1. Com comando vgs verifiquei que pve ainda tinha espaço livre:
   root@pve2:~# vgs

 VG       #PV #LV #SN Attr   VSize    VFree
  pve        1   3   0 wz--n- <223.07g 7.30g

2. Confirmei a informação com o comando:
   # vgdisplay pve
Free PE / Size 1869 / 7.30 GiB

3. Depois, com o comando abaixo, me certifiquei do tamanho da minha LV
   # lvdisplay pve-root

Free PE / Size 1869 / 7.30 GiB

4. Depois redimensionei minha LV em mais 7Gigas
   lvextend -r -L +7G /dev/pve/root

5. Confirmei que ela havia sido redimensionada com o comando abaixo:
   lvdisplay /dev/pve/root

6. E para garantir, verifiquei com o comando abaixo:
   lvdisplay /dev/pve/root

Me inspirei no poste abaixo para essa solução, espero que ajude!

To recreate pve data using 100GB of space: lvcreate -L 100GB -n data pve

You can find how much space is free with vgdisplay (under "FREE PE / Size")

Note that you might need to decrease the size by a tiny bit from what is listed there, due to rounding. For example, on my server, vgdisplay showed 267.79 GB free, but I had to use 267.78 GB for lvcreate.

I found this document that helped me loads.
The main problem was that LV data took up all the space.
