Resizing Disk

[Binksy]

Hey

Made a slight error on installation in that all of the drive was not allocated correctly.

I need to change the local storage to be 100GB in total, and the remaining to be allocated to local-lvm

pve2 is a secondary drive

lvs

LV               VG   Attr       LSize   Pool Origin Data%  Meta%  Move Log Cpy%Sync Convert
  base-6100-disk-0 pve  Vri---tz-k  90.00g data

  pve2             pve2 twi-a-tz--  <1.07t             0.00   0.18

pvs

  PV             VG   Fmt  Attr PSize    PFree
  /dev/nvme0n1p3 pve  lvm2 a--  <199.00g  16.00g
  /dev/nvme1n1   pve2 lvm2 a--     1.09t 120.00m

vgs

  VG   #PV #LV #SN Attr   VSize    VFree
  pve    1   7   0 wz--n- <199.00g  16.00g
  pve2   1   1   0 wz--n-    1.09t 120.00m

So I am unable to resize using lvextend or other commands, as I think it's seeing the drive is partitioned fully, but that isn't the case. LVM is showing local has 62GB and local-lvm has 121GB

The drive is a 1TB drive, and would need it to be allocated as approx. 100GB to be for local storage and the remainder (900GB Approx) to go to LVM-Thin pool, but I can't seem to get that to work?

Just wondering what I am missing with this

TIA

There is really no easy way to reduce/shrink existing volume group, especially when you have lvs already allocated in them. You can find many discussions about it online, ie https://unix.stackexchange.com/questions/67702/how-to-reduce-volume-group-size-in-lvm
Your best bet is to :
a) migrate your VM disks from PVE to PVE2, you can use "move disk" option
b) remove lvm-thin pool (first from PVE, then manually from disk)
c) extend your root LV and filesystem as desired
d) recreate lvm-thin pool from remaining space
e) optionally: move VM disks back

good luck
