Not using full disk space

Installing and Using OpenWrt
1

Hello,
I'm using OpenWrt on a Zyxel M1. Works fine so far.
But I noticed that I don't have much disk space available. I just looked up the specs and there should be 128MB of NAND flash in total.
When I check the status it says:
Disk space: 17.99 / 20.61 (87%)
Temp space: 1.04 / 122.23 (0%)

Why is the temp space so big and the disk space just 20 MB?
In the software section it says "free space: 12% (2.61 MiB).

I haven't really installed much but the general question is how to make more space available?

temp (tmp) is RAM.

flash space is based on stock fw layout, openwrt doesn't allocate 100% of the flash.

3

temp (tmp) is RAM.
But why is there a section for memory where it says "total available 244 MiB..."

Do you know how I can give OpenWrt more disk space?

you can build your own image, and replace (might be required) the boot loader....

or get a router with an USB port.
