/dev/root is full, how to make space

[Sebastien Thiry]

Hello,

I have an Omega2+ that works correctly but the /dev/root that is mounted in /rom is full, I have already do the factory reset but nothing change.

root@Omega-C3FD:/rom/lib/modules/4.4.46# df -h
Filesystem Size Used Available Use% Mounted on
/dev/root 5.5M 5.5M 0 100% /rom
tmpfs 61.4M 96.0K 61.3M 0% /tmp
/dev/mtdblock6 25.1M 2.7M 22.4M 11% /overlay
overlayfs:/overlay 25.1M 2.7M 22.4M 11% /
tmpfs 512.0K 0 512.0K 0% /dev

Someone can help me with this?

Thanks in advance

Here is a tutorial on how to expand Omega's storage with SD card or USB flash drive

I think /dev/rom is supposed to be "full". It's just the partition where read-only code is stored. You've got 22.4 MB free on /overlay, which is perfectly reasonable after a factory reset. Also matches this screenshot here.
