Question

Hello All,

My /dev/root partition is full:

Is it expected or indicating some problem?

Thanks,

Hi,

This filesystem is supposed to be used 100 %. Default WebUI files, configs, etc. are kept there, so the space is reserved

You can read up more here: https://www.kernel.org/doc/Documentation/filesystems/ramfs-rootfs-initramfs.txt

Rootfs is a special instance of ramfs (or tmpfs, if that's enabled), which is
always present in 2.6 systems.  You can't unmount rootfs for approximately the
same reason you can't kill the init process; rather than having special code
to check for and handle an empty list, it's smaller and simpler for the kernel
to just make sure certain lists can't become empty.

Most systems just mount another filesystem over rootfs and ignore it.  The
amount of space an empty instance of ramfs takes up is tiny.

Perfect. Thanks

Hi,

Do you run any custom scripts on your device ? Also what services are you using ?

Can this be a service/operation impacting (l mean partition usage)?
