Scenario
I expanded the disk space, from a kvm in proxmox.
By mistake expand instead of 50 GB expand 500GB
Well, when I did the vps check with dmesg | grep vdb and with fdisk -l /dev/vdb | grep ^/dev I realized my mistake
Choose to stop the machine and do a disk shrink with
lvreduce -L -400G /dev/lvm/vm-109-disk-1
WARNING: Reducing active logical volume to 800.00 GiB.
THIS MAY DESTROY YOUR DATA (filesystem etc.)
Do you really want to reduce lvm/vm-109-disk-1? [y/n]: and
Size of logical volume lvm/vm-109-disk-1 changed from 1.22 TiB (320000 extents) to 800.00 GiB (204800 extents).
Logical volume lvm/vm-109-disk-1 successfully resized.
Now when I start the system and went to work as I usually do when I enlarge the disk, I found an inconsistency that does not allow me to fix the real space.
Usually to expand I do the following (1 is partition grow)
parted /dev/vdb
(parted) print
(parted) resizepart 1 100%
(parted) quit
Previus
pvresize /dev/vdb1
Physical volume "/dev/vdb1" changed
1 physical volume (s) resized or updated / 0 physical volume (s) not resized
But I see I don't change
pvscan
PV / dev / vda2 VG lvm lvm2 [<24.51 GiB / 0 free]
PV / dev / vdb1 VG lvm lvm2 [<600.00 GiB / 0 free]
If I try to use parted to see the state both in console and starting the vps with LiveParted I have the same error
GNU Parted 3.1

Vps is work perfectly but disk is unresizeable...
