Well, I will refer myself on a topic related to that :
https://docs.onion.io/omega2-docs/boot-from-external-storage.html
Filesystem Size Used Available Use% Mounted on
/dev/root 7.8M 7.8M 0 100% /rom
tmpfs 61.0M 236.0K 60.8M 0% /tmp
/dev/mmcblk0 29.3G 146.7M 27.7G 1% /overlay
overlayfs:/overlay 29.3G 146.7M 27.7G 1% /
tmpfs 512.0K 0 512.0K 0% /dev
/dev/mtdblock6 22.6M 22.0M 536.0K 98% /mnt/mtdblock6
If we do consider some element that differ from the tutorial, it work.
In my case, I loss my work...
Now I've got plenty of space.
Myself:Thank you for your help.
Myself:No problem
