[Question] Resizing Proxmox local / local-lvm? (lemmy.ml)

I'm dangerously close to running out of space for my VMs on local-lvm, but noticed I have a lot of free space in my local storage where I only have a dozen ISOs stored.

Can anybody help me figure out how I'd go about shrinking the local storage so I can extend my local-lvm?

Create a new storage pool with bigger disk(s) and migrate your stuff

Much less of a headache.

You could also add a directory to your local-lvm storage and set that to be your iso store in datacenter-> storage

It’s really that much of a hassle to fiddle with the volume sizes?

[–] krolden@lemmy.ml 1 points 7 months ago (1 children)

Its definitely more of a hassle than adding another storage pool or creating a directory in local-lvm.

[–] brownmustardminion@lemmy.ml 1 points 7 months ago (1 children)

You suggested just adding the ISOs to local-lvm. Do you think it would be feasible to simply delete the local storage completely and then extend the local-lvm after, storing the ISOs there? I know extending volumes is much simpler than shrinking. And I imagine deleting completely is also easier than shrinking?

From the comment:

This is how I do it:

boot into gparted (make bootable usb https://gparted.org/liveusb.php)

open terminal

run lvdisplay to check the proxmox root and data lv name and path
sudo lvdisplay

resize the root lv (choose size, no curly brackets)
sudo lvreduce --resizefs -L {size}G /dev/pve/root

resize the data lv to use all available space
sudo lvresize -l +100%FREE /dev/pve/data

reboot into proxmox
pray

I do not suggest doing this. Just add another disk.
