Small storage on netgear wax206 but big /tmp

hello, I am using netgear wax 206, where do i made a mistake with such a small /overlay storage and such a big /tmp. I 've been planning to install adguardHome, but not enough space. Can I expand storage somehow?

Filesystem Size Used Available Use% Mounted on
/dev/root 4.0M 4.0M 0 100% /rom
tmpfs 245.0M 2.0M 242.9M 1% /tmp
/dev/ubi0_1 18.1M 14.9M 2.3M 87% /overlay
overlayfs:/overlay 18.1M 14.9M 2.3M 87% /
tmpfs 512.0K 0 512.0K 0% /dev

tmp is RAM, it goes away upon power off and reboot.


The device has no USB port.

It seems normal, actually.


It's a dual fw device, too.


Oh yea!

That explains a lot more absent space too.

so it is not possible to use adguardHome with such an advanced router netgear wax 206?

if it doesn't fit, it doesn't fit.
but it seems you've already filled /overlay with other packages, up to 87%.
