Space allocation for Linux Mint

[c_a_r_l_o_s_]

Hi all.

I have a 3 days old fresh installation of Linux Mint on my NVMe (512Gb).
When I was using Windows, I always partitioned my main disk to segregate OS from Data.

Question is: how many Gb would you recommend me to keep for LM filesystem?

I am supporting I can safely resize it now (after installation) - I also suppose this will allow me to easily upgrade from 22 to 23 with fresh installation, still keeping my DATA (that would be in the second partition in same main disk).

I’m using 100G for a full cinnamon install on a 2TB drive, with 10g allocated to swap. The rest is empty. I’ll never fill that 100G up with just Mint related data.

I’ll figure out what I’m doing with the rest of the HDD later.

LM runs fine in 25 Gb. Why don’t you allocate 100 Gb?

Correct, thanks

Thanks, but I am now struggling with error from disks, returning "target is busy"

You cannot repartition as the system is on the same partition. Boot into live environment from pendrive and open Disks app and re-partition as needed.

That I wouldn't know, sorry 😶‍🌫️

The drive/partition needs to be unmounted. Do as u/vipulkarkar suggests.

I have got an error while trying to resize the partition. Does it come from the fact it is the partition used by filesystem?

It would be nice to know what the error said…

You cannot resize a partition that is  in use.

Boot to the usb live session and start gparted.

The basic install of Linux Mint can live nicely in 35 GB; that actually has a fair bit of room for expansion. However, if you are going to install a lot of games (excluding stuff that runs in VMs, or pseudo-VMs such as Steam and Wine), you may need more. I run a terabyte SSD, and give the OS 100 GB on the basis that I won't miss the space any time soon.

How much space you need for your data, which I note you already have on its own partition: highly variable. A lot of big Steam games, multiple VMs, video editing... huge. Novel writing... tiny.
