#Changing local + local-lvm disk size during initial install

My quest to change the disk size during the inital Proxmox install is turning into a Herculean one.
I have one 500Gb disk in my homeserver. With a default setup that results in a +-100Gb local storage and the rest for local-lvm. That is not ideal, as the local backups have only limited space on local.
Ideally I would have about 200Gb for local and the rest for local-lvm.
Despite googling far and wide and testing various scenarios I connot figure out how to change this.

People have pointed me to Advance Settings, but I don't see anything that has the desired effect.
In the Target Harddisk screen I can change HDsize, swapsize, maxroot, minfree and maxvz.
These threads seemd appropriate: https://forum.proxmox.com/threads/question-about-minfree-maxroot-swapsize-and-ext3-ext4.19000/ + https://forum.proxmox.com/threads/proxmox-install-local-minimal-install.85695/ but alas.
Maybe I am not understanding it, or I am overlooking options?
I am not even sure if what I want is actually possible with just 1 harddisk.

If anyone can help me I'd be eternally grateful.

Question about minfree, maxroot, swapsize and ext3 / ext4

I have some doubts about this values?

What is the recommended values for:

maxroot = XX
This will be only used by the system root?
We will need some space in partition in the future?
Temporary lzop files for backups is stored here?

swapsize = XX
This really need to be the same value of our...

[SOLVED] - Proxmox install (local) minimal install

I usually use the ISO to install Proxmox but it's very wasteful of drive space where it will automatically allocate about 100 GB to the local storage. Is there a way to tell Proxmox not to use that much space or do you have to install the OS First and then add Proxmox?

If you have to install...

Did some more searching, and I'm starting to think what I want is not possible.
If I only have 1 HDD there is no way of configuring the local storage (w/backups and templates) to be larger than the default x percent of the total HDD size.

There is a way to repartition them but I wouldn't recommend it. I did it a few weeks ago because I don't even need local for anything, I backup to an external storage and for iso's I don't need that much space.
I don't really know the exact steps I took to get them resized because I tried different things until it worked 😄

So there is no standard way to do this during the setup? That's all I need to know. Thank you!
I'll see if I can find another ssd to add for a separate local storage.

Couldn't help myself and did some extra testing.
With these settings using a vm with a 50Gb HDD:

  • swapsize 1Gb
  • maxroot 10Gb
  • minfree empty
  • maxvz 10Gb
    I get this:
  • local storage of 10.46Gb
  • local-lvm storage of 8.59Gb
  • pve-root of 10Gb

Approximately 29Gb is unused and I have no idea how to make that work.

Would've expected local-lvm to be 10Gb and local about 39Gb. Or I have understood the various docs wrong.
