/overlay on WR3000 is only 6MB

[hax]

Hello!

I just found out about this router and it has 16MB flash but when I execute df -h I am only getting 6.6MB can you please help me regain the missing 10MB?

root@OpenWrt:~# df -h
Filesystem                Size      Used Available Use% Mounted on
/dev/root                 4.5M      4.5M         0 100% /rom
tmpfs                   117.3M    220.0K    117.1M   0% /tmp
/dev/mtdblock8            6.6M    360.0K      6.2M   5% /overlay
overlayfs:/overlay        6.6M    360.0K      6.2M   5% /

Is the Openwrt firmware stored externally ?

You'll never get 16MB, read the flash size paragraph on top of https://openwrt.org/toh/start

cat /proc/mtd to understand where the rest went.

Right! Thanks for the reply. I should have looked better into TOH indeed.
I just did not pay attention to it. btw cat /proc/mtd results this:

mtd0: 00040000 00010000 "BL2"
mtd1: 00010000 00010000 "u-boot-env"
mtd2: 00010000 00010000 "Factory"
mtd3: 00010000 00010000 "bdinfo"
mtd4: 00080000 00010000 "FIP"
mtd5: 00f10000 00010000 "firmware"
mtd6: 00400000 00010000 "kernel"
mtd7: 00b10000 00010000 "rootfs"
mtd8: 00690000 00010000 "rootfs_data"

I think I understand the structure but I would be interested into modifying it to have more room for packages. Any idea?

Yes, it's doable, but it'll be your spare time project.
