change size of pve-root partition while installation

[support_helpcorner]

i want to install proxmox on a 18 GB SSD

when i use "Default options" while installation, then the HD Space (root) is only 4.37 GiB, which is to small.

then i tried with "swapsize = 0, maxroot 10, minfree 0, maxvz =2, but still HP Space (root) still to small (4.5 GB).

what parameter do I have to enter, go get a HD Space (root) at a size of minimum 9 Gib?

hmm - quickly skimmed through the code - and yes there is a hardcoded limit of max(maxroot, hdsize/4) there ...
you can set the minfree higher - this would add another hdsize/8 (you can use lvextend for resizing the root lv and then resize the filesystem.

if that is still not enough - you can (as long as there's no data on it which you need) - remove the data thinpool, then extend your root-lv (and recreate a smaller thinpool if you wish)

as a last resort you can always install PVE on top of debian buster:

I hope this helps!
