No left space on /

Hi im new in the community,
i’m using home assistant for 2 years, i’m using HA OS
Now i have problem with disk space, i can’t resize the /dev/root mounted on / because partition is uknown and not partition table is installed (via gparted or fdisk)

Any idea to fix it?

Anyone has the same problem?

Thanks
