Hi
I have a 3TB USB disk /dev/sda1 with a single EXT4 Partition.
I want the filesystem to use the whole partition but the fs appears to be only about 11MB and showing 82% utilised
OpenWrt 19.07.7 r11306-c4a6851c72 / LuCI openwrt-19.07 branch git-21.086.32701-7456e2a
df mnt/
The filesystem has approx 10MB in use and is showing as 81% full

I have tried resize but this seems to say the fs it max size :-
root@OpenWrt:~# resize2fs /dev/sda1
resize2fs 1.44.5 (15-Dec-2018)
The filesystem is already 732557824 (4k) blocks long. Nothing to do!
I want the filesystem to use the whole partition?
I am new to openwrt/Linux, please can you point me in the right direction.
Thanks in advance.
