[pve-devel] [PATCH pve-installer; pve-docs; pmg-docs; proxmox-backup/docs 0/4] Update min RAM and min disk size for pve

[Noel Ullreich]

Note that this patch series needs the patch
`tui: don't abort install if min ram requirement is not met`
(https://lists.proxmox.com/pipermail/pve-devel/2023-July/058057.html) to
apply.

This patch series does two things:
1) It raises the minimum usable RAM the installer checks for from 1 GiB to 2 GiB.

Up until now the installer checked whether the system (pve, pmg and pbs) had at
least 1 GiB of usable RAM or else it would display a warning. However,
the pmg and pbs docs specify a minimum of 2 GiB of usable RAM. Off-list,
Thomas recommended having a min of 2 GiB for all products:

"We could just update the docs to use 2 GiB as minimum as:
- for PVE one normally wants more RAM anyway, for running guests and
   all that
- for PBS it just makes sense to have a good amount available for page
   cache
   or ZFS ARC
- for PMG the clamav service alone eats almost a GiB, so 2 GiB aren't
   that
   unrealistic there either."

2) It updates the docs to specify the minimum disk size for a pve install.

As of now, the pve docs do not specify the minimum disk space needed for
a pve install. Extrapolating from the Debian min requirements 
(https://www.debian.org/releases/bookworm/amd64/ch03s04.en.html) the
docs recommend a minimum disk size of 16 GiB. Leaving all the default values
in the installer (i.e. not changing any lvm-thin/swap sizes), this gives
a root directory of 6.8 GiB.

[pve-devel] [PATCH pve-installer 1/1] raise the minimum ram requirements to 2 GiB

[Noel Ullreich]

Check that the system has at least 2 GiB of usable RAM.
The docs for the pmg and pbs (and with this patch series pve as well) already
specify 2 GiB as the minimum RAM needed.

this is using the wrong unit though, we use the SI based GB for
disk space, as most storage vendors do, GiB is fine for memory though.
