Extending mountpoint on LXC

[Namudril]

Hello,
I'm running pve-manager/7.3-4/d69b70d4 with a Debian 11 based LXC.
I've created a new LVM storage with a 500G disk, then added a mount point to LXC 100 via GUI, size=200G
Now I want to extend mount point to 500G
What are my steps to do?

root@pve:~# pct config 100xc/100.conf
arch: amd64
cores: 3
features: nesting=1
hostname: plex
memory: 2048
mp0: storage:vm-100-disk-0,mp=/storage,backup=1,size=200G
net0: name=eth0,bridge=vmbr0,firewall=1,gw=192.168.1.1,hwaddr=36:5C:A1:B5:A6:B4,ip=192.168.1.15/24,type=veth
onboot: 1
ostype: debian
rootfs: local-lvm:vm-100-disk-0,size=8G
swap: 2048
unprivileged: 1

Hi,
you can select the mount point in the GUI and select Volume Action > Resize adding 300G there. Or you can do it via pct resize (see the man page for details).

Thanks! That works.
I've made a mistake at first, extending LVM f that storage, thus no space for MP extending left available.
I have made

lvreduce -L 200G LV-name

and then

Volume Action > Resize
