I bought this router which should have 128 MB of disk space.
Yet after installation of relevant release of OpenWRT I can only see 18MB:
% df -h
Filesystem Size Used Available Use% Mounted on
/dev/root 2.8M 2.8M 0 100% /rom
tmpfs 60.5M 1.1M 59.4M 2% /tmp
/dev/ubi0_1 18.3M 11.7M 5.6M 67% /overlay
overlayfs:/overlay 18.3M 11.7M 5.6M 67% /
tmpfs 512.0K 0 512.0K 0% /dev
Is this just a matter of configuration, a partition is too small (hard to check, somehow I do not have block command available that OpenWRT docs recommend to check for this)? If the disk is actually bigger, how to extend it?
