I have OpenWRT installed on eMMC. How do I use the full 8GB to have more storage for e.g. docker images?
Filesystem Size Used Available Use% Mounted on
/dev/root 84.0M 84.0M 0 100% /rom
tmpfs 1.9G 2.5M 1.9G 0% /tmp
/dev/fitrw 356.4M 53.2M 303.3M 15% /overlay
overlayfs:/overlay 356.4M 53.2M 303.3M 15% /
tmpfs 512.0K 0 512.0K 0% /dev
overlayfs:/overlay 356.4M 53.2M 303.3M 15% /opt/dockerI see there’s opt/docker but it has limited space. I see it says overlayfs. Is this persistent?
